[simon_c]

5 mods I've loved:

• Supersprint sport exhaust
• Evolve eventuri intake
• E60 shifter + new shift cup/bushings
• ZHP shift knob + new shift boot
• Rewrapped leather steering wheel with increased thickness

Mods I didn't love:

• Blacked out kidney grills/side grills
• Tint (esp trying to take it off)
• The front lip that the original owner put on
• Aftermarket air filter (didn't do anything on a stock intake)

I bought a second m3 on Friday, driving home currently and have done about 1000 miles so far. It’s mostly stock except for some lowering springs, and I can tell that some parts of the car are original and worn out (it’s an 05 with about 100k on it).

From this drive, I’m really missing these things:

1. 3.85 ratio rebuilt diff.
2. 17” wheels and 275s
3. RTD Shifter
4. My ground control coil overs.
5. Headers and Tune.

Things I will be leaving stock/replacing with new genuine parts:

1. Cooling System
2. Chrome grills
3. New multifunction steering wheel in leather (new car is a ZCP with worn out alcantara.
4. Swapping the nav for a business cd and bluebus
5. I won’t be doing an accidental diffuser delete like I did on my previous m3

For the most part, i liked most of the mods i put in the car. But here are some I loved and some I liked less.

Loved
1. KW clubsport
2. Apex EC-7 18" square setup
3. Schrick 280/272 cams
4. Supersprint exhaust (SSV1, section 1 w/ euro cats, resonated section 2 and sport muffler)
5. ZCP steering rack

Bonus - regular maintenance.

Liked a little less
1. CSL airbox with map and working snorkel. Glorious sound, but added stress from emission compliance.
2. 996 bbk conversion. Works well but needs a 20mm with my zcp wheels upfront.
3. Manual swap. I always enjoy a good manual, but I do miss the SMG on the track and the quick downshifts.
4. CSL kingpin. Not sure if i felt a big difference.

Not much has been done throughout the years I've originally owned the car & I've only recently bought it, so kinda feeling like I'm listing all the mods. lol

Loved:
Autotechnik Halos
Megan Racing prototype exhaust
Front bumper QD pins
Apex FL-5 18x10 square set up
KW V2s


Not so Loved:
Avant 4 - for the money I was expecting a better plug+play
Hawk Pads - in-between owner had to replace during the height of the pandemic and it was the only thing he could get his hands on
Seibon CSL boot lid - loved at first since it came with the car, but over time it crapped out and buckled. Will be saving up for the new Karb lid
BC camber plates - hate that you have to drop the front suspensions to adjust them. will be switching to turners or vorshlag in the future
Driver - Always complains and nit-picks, too cautious, always spends too damn much on the car

I wanted to go OEM bumper and diffuser but just couldn't for that price. Ended up going Miles End for both. Just waiting to get them painted and installed. Picked up an OEM trunk though to replace my karbonius one. Excited for that.

My M3 has 6K miles. Easy to justify dumping another $7.5K in genuine BMW parts. Fikses are $11.5K USD w/ PS4Ss. Pre-tariff is the justification. lol

Enjoy the OEM CSL trunk. Only way to fly.

I drove with an Eisenmann Race Section 3 for about a year and absolutely loved the note when over 4K RPM. Some lower RPM drone but the backbox was magical (if you enjoy rasp and the highly metallic sound of the engine amplified by the exhaust on downshifts).

I was debating between the Race and Sport, but took a flyer on the sport as I cannot stand drone. I heard the noise difference isn't too drastic between the two? I really appreciate your input.

I had the luxury of hearing both the sport and race on completely stock exhaust systems and the race exhaust as easily louder and more enjoyable. The sport is muffled and IMO starts to sound like the Dinan Section 3 which is quieter but still audible. Depends on whether or not you want that really loud note when you’re stepping on it. Riding along any center divider on the freeway and going through 7K RPM or downshifting between 3rd and 2nd had everyone turning to look at what kind of machine was coming through… just too good. I’ll put it back on one day, but for now I’m working through a valved titanium exhaust that I’m tuning to open/close at various RPM ranges for each gear.

Not into that. Sport it is.

Haha, true that.

To each his own! Enjoy.

The sport left me wanting a little more sound, I've since deleted all of the resonators and still want a tad more. Another disappointment with the Eisenman is the equal length tips, why are they not staggered? I love the styling, went with the 76mm which are perfectly sized for the opening. Fortunately, I picked it up used and it'll stay for the time being. I know I'll have to rework the resonator situation when I get headers, OEM euro with the sect 1 cats may be ok.
