Cockroach Individual M3 4/1 Drivers Window Replacement

[samthejam]

As promised, only did the front rotors for now. Rear rotors still good so want to get moneys worth out of those.

I daily drive with the PFC 08s so the brake dust is horrednous.

Had a wedding

Instead of honeymoon, decided to do headers. That was a debacle.

Has a really interesting exhaust note, definitely doesn't sound like the BW exhaust I have mostly heard.

[samthejam]

Ordered the Reddish subframe reinforcement and AKG 75D subframe bushings, so that is next. My suspicions of the car having a tune have been confirmed, cat deficiency always showed as not ready. No CEL yet after the headers. When we did the CSL shift setting and 105 DTC error disabled. We used Martyn's tool and Cat deficiency was greyed out. I saw this before on a friends car but it was for the burble setting, so someone has tampered with it and software won't let you touch that setting. So no idea what's on it but someone has cooked here before.

CPV valve is starting to leak but didn't have the tool or the part so that is ordered as well.

[George Hill]

congrats on the wedding!

[samthejam]

Thanks George!

Took Friday off work, after a friend offered he could help weld in the Subframe plates. I had to rent the shop space, but that's okay. Was able to align it there and everything. I also paid my friend for the labor of welding, cutting and grinding basically hot glueing the plates in and repairing any damage. Glad I did came out better than I would've. Picture of on my way there.

Onto the pictures.

After an hour or so

It was time to replace the subframe bushing with AKG 75D as well as replace the cracked right rear spring arm, I had been fully relying on the stainless steel reinforcement to hold it together. Even though I was at a BMW specialist they did not have a tool that was fairly easy to remove the subframe bushings. However I brought my RTAB tool because I thought I read that would work. It didn't, but I fiddlefucked with it and made it work.

Worked like an absolute treat with the torch. No impact just a regular 3/8th ratchet. Hammered the new AKGs into their new home.

Onto the spring arm and guibo. I sourced a brand used one.

Basically where it stopped for Friday, besides having the area cleaned and inspected. We found 3 areas that were cracked.

Came back Saturday morning and my friend was feeling a lot better and cranked it out.

Welded up the cracks, and note the gas tank is still in there. Those got covered with wet towels when welded. The Reddish plates were huge so we trimmed them a bit, as I did not want to mess with dropping the tank. I did show up with it with less than a gallon, but we worked around it.

I also found a Hotchkis swaybar laying around the shop, so put that on. Was very pleased about that.

I haven't been able to do my alignment myself on a machine in a long time, so that was a fucking treat.
Untitled by Kurvenkamph Motorsport, on Flickr

Forgot to take a pic but -3.5 camber in front, zero toe, didn't hit my camber number I wanted on RR for some reason. So it was -2.0 and -1.6, rear toe is just factory specs.

Car drives great, absolutely transformed can feel what the rear end is doing now and the front bar really helped with the softer spring rate I have up there.

Total time spent doing everything was 24 hours, two 12 hour days.

[jayjaya29]

Big 3 done!

[cornerbalanced]

Have you measured your ride height yet as it sits now? Sorry if I missed it.

Alignment spec is -3.5 front (no toe), -2 rear (factory toe)?

Love those SSRs!!

I keep forgetting to check this. I forget exactly what it is but I remember raising the rear because of this thread.

It is somewhere in this window but I am limited in what I can do since my fronts are at max height with this GC setup until I get taller springs but I like the height so probably won't change.

So got the strut towers finally welded, they have been cracked since I got the car as well as the Strut brace. My friend was able to tig it in the car with everything still assembled.

I signed up for an impromptu event at MSRH, my local track. Very familiar with this place, and aren't many consequences here for most places when you push so it's great to feel a car and test it out. I was really low on rear pads, so just wanted to get one test session in. They had some portable curb things to move the apex's which in a couple spots was terrible like into Gut Check and coming out of Keyhole were the most irritating ones.

Car is super easy to drive though, the new Hotchkis bar was a nice addition. It is at the softest setting right now, might want to stiffen it but the balance of the car is very good. Overall it is too soft so on the 265 Rs4s now it is okay but if I start running fresher Hoosier takeoffs or even RE71RS I am a bit concerned itll be a bit soft. But anyways car was boogie'ing. Annihlated my PB here I did in the E28 on Hoosiers.

Untitled by Kurvenkamph Motorsport, on Flickr

Here is a lab of the PB:

Unfortunately after that PB car bit me and the thermostat went into the water pump. So the car has been running extremely cold, which has been tough to daily drive with since it's finally getting moderately chilly here in Texas. I had a used thermostat on standby, but was debating on going the Anri 70C or motorsports thermostat. Red light of death luckily never came on caught it quick and was able to coast/ limp car into pits.

I had a friend drive me back home to grab the thermostat, as I suspected that was bad since the top hose was hot and bottom room temp. I thought the thermostat froze shut. I brought my spare used water pump as well just in case. Glad I did.

I also was lucky enough to have this which I had on hand just for emergency's.

https://nam3forum.com/forums/forum/classifieds/member-services-rentals-products/4125-m3-s54-cooling-system-hi-temp-o-ring-kits

Was able to get the car all patched up with the brand used parts and new orings and it left under its own power.

Systems check the following day.

So if you notice all the parts that were removed are absolutely covered in RTV (I hate RTV). Well one connection was not and I think this thermostat has been out for a long time. So when we were assembling everything, the water pump pipe stayed with the thermostat housing. We found out it cannot be assembled like this. So we got the pipe out which took quite a bit of time as it had never been seperated.

Now it's hard to say since my thermostat came out in many pieces. However my hypothesis is the monkey who was in here before and replaced the water pump (2010 date code) as well as the thermostat did not know that pipe needed to be be in the block/head first. He jammed it all together somehow, and this bunged up the thermostat. Since I got the car it had a coolant temp implausible code and then I deleted that DTC. My guess is, it has been like this for a long time but anyways all correct now.



There will be a HPDE next weekend I'll be instructing at will test car more. Then it will go on a long roadtrip and get a day of beating on at Road Atlanta the following weekend.

[samthejam]

Alright so another update.

Very big update, not in terms of building the car but moreso in sharing the adventures the car has been on.

So the last update was me at MSRH, and that's where this will post will start off but it is the following weekend. It was miserable out, but a good low stress way to test the car out before heading to Road Atlanta.

MSRH is horrific in the wet, there is a 10-15 mph difference between the wet line and the dry line for corner speed. It is an ice skating ring. So there were many sideways moments, but I have done many laps here so I am comfortable in the wet.

I almost got bit here...

https://youtube.com/shorts/JCqtRzrYvLA?si=hvRimtCbGoDnNVDp

It was just cold and wet but I got a lot of laps in. Car looked like it was ready for the big trip. I put some Direzzas on it since they were on closeout and for peace of mind of new tires for the whole trip. Rear pads were paper so bought some new PFC 08s for that. Also aligned it again. This time I did stock toe for the front, I don't really like the feeling of zero toe, but the main reason was to give the tires best fighting chance for all the highway miles.

Anyways onto the Roadtrip. Cannonball to Atlanta, in one shot from Houston. Weren't any issues.

Went to the Aquarium and explored downtown Georgia for a bit. jayjaya29 was nice enough to let me stay at his home and use his workshop to do a bit of trackprep. These 265 Direzzas are significantly wider than the RS4s so we needed to do some fender hammering, as the damage from previous owner wasn't giving it enough clearance.

I knew the car would blow sound at AMP, but I was able to get a couple laps. It was miserable and raining. 107db, is what I got blackflagged for.

Fall ‘24 Update by Kurvenkamph Motorsport, on Flickr

That evening I did the SAP delete and did a P/S flush as the system was pretty angry.

Fall ‘24 Update by Kurvenkamph Motorsport, on Flickr

Then it was time for Road Atlanta. It did dry up after Lunch, but the morning sessions weren't wet. Morning sessions were trouble free.
Fall ‘24 Update by Kurvenkamph Motorsport, on Flickr

Didn't bother recording with Go Pro. My wife was able to get some external videos.

This event was sold out, so there was a lot of traffic. When it did dry out, I came over turn 3 pretty hard. My instrument cluster did not like this and started acting up all day. Would come in and out, and during one session the tach started touching the oil temp needle so I had to start short shifting. Despite this, I was able to set a new PB, however I was not able to meet my goal of a 1:39.99 here. I had multiple instances where it was showing up on predictable but ran into traffic or cluster would spazz out and distract me.

Fall ‘24 Update by Kurvenkamph Motorsport, on Flickr
Fall ‘24 Update by Kurvenkamph Motorsport, on Flickr

By the end of the day the cluster was struggling. Braking would make it cut out and only work with dimmer at lowest setting. We still had to go to Charleston to see my wifes family I needed to fix it, but I delayed this by a day to give myself time to sort out the cluster. I put out a WTB for a cluster just in case but took it apart at Jay's that night.

I really didn't think it was fixable but luckily was something simple. Please click the Flickr link to see what it was but basically one of the Capacitors had come off the board with the pad.

Fall ‘24 Update by Kurvenkamph Motorsport, on Flickr

Jay was able to repair it for me and cluster was alive again. Also tightened up the shock nut.

Following day, Faustino and I did an impomptu run to Tail of the Dragon. My plan was to head to Charleston that night so we would just go to the Tail do one run and come back.

Ended up working out perfectly. We had no traffic. Cars didn't really give any trouble, besides mine the power steering had basically no assist at idle after second run.

One of my favorite pics of the car so far.

Fall ‘24 Update by Kurvenkamph Motorsport, on Flickr


We ended up heading to Charleston at 3am since I was beat. Needed some sleep. We did Atlanta to Charleston, in one shot. I was on fumes when we got there, and first time ever filling up with 91 in my life. I've always had access to 93.

Tried to do another halfass resevoir flush to bandaid it along but at this point needed a new pump.

I was having a brake shudder that was pretty bad felt like a rear rotor. I felt it on way back from Charleston. Not sure what caused it but sure enough. I believe just the Metallurgy of these cheap drilled and slotted rotors. Unfortunately I put another used set on because my friends parts car had them. We traded them some stuff for it.

I need to fix the cracked wheel so I can have 4 matching wheels.

Also was able to find some NOS PFC 83s for it. Yes you read that right 83, can't imagine how long those have been sitting on the shelf. Threw those in on NYE. Yes I am running the pad clip.

[samthejam]

The total mileage for 2024 was 14,448 miles.

I also didn't realize that this color was so rare. So I should probably look into making it shiny for 2025.



Current Projects for 2025:

- 6 Speed Swap
- Passenger Recaro Profi
- Roll Bar and Harness
- 4 Matching SSRs
- Look into getting Hood Painted
- CSL Front Bumper
- Drive that bitch

[samthejam]

Had another DE. Car did well, blew my expectations out the water in terms of the pace it could do. The high bite front pads were fantastic, huge confidence boost. The 08s work on my E28 but they were terrible for me on this car. I am a big PFC fan, but they just didn't work for me on this car. When these 83s run out, hopefully the 11s will fill the void. I believe DTC-70s would work as well but not a fan of Hawk Pads.

A bunch of 47s with passenger and was able to squeeze out a 1:46.67.

Yeah my cross country adventures can be a bit bold.

Here is my welding my E28 strut housing to get back home after the used Hooisers sheared it at Barber.

[M3Garand]

Great build

[samthejam]

I got the SSR welded up. I'm not happy with how it got repaired at all but, what're you gonna do.

I also found out my rack had endplay and was binding. So I found a yellow tag from the yard pulled it and installed it, did that Saturday. Sunday I jumped on a deal from Dallas, some AST 4150 installed and aligned the car. Not too happy with them yet but old GCs were very worn out. However the car has now lost how easy it is to get in and drive. So idk what Im going to do yet.
