Dumb Question Thread - No Flaming Allowed

What would I be sacrificing running the hawks? ..initial bite? I didn't read any bad reviews, so i'm curious.

I also am not looking for completely dustless... just less than the texar pads.

I ran the Ferodo Ds2500's last weekend at the track despite what I have read here. I loved them compared to the OEM pads. Less dust, better modulation and no fade for me compared to the OEM pads at the same track a couple of weeks before.

Typically, HPS gives a bit more fade resistance than the stock pad but might generate less initial bite and more noise. Also, as a rule of thumb, you can expect rotor wear to be on the fast side with a Hawk compound than with many/most comparables. It all varies by application though and I'm not familiar with this one.

I also had a decent experience with DS2500 on track. It was noisy on the street, though. And holy hell does it wear quickly on track.

The HPS pad has less initial bite than stock and the HP+ pad is noisy. In my experience, non-OE pad compounds also can leave pad imprints on the rotor that are really hard to get off if you wash your car and park it immediately after.

At the end of the day you just have to try several different pads to see what works for you. I love ferodos (1.11s) on my other car, good feel and gentle on rotors, but they do give me a long pedal after about 1/2 pad life even on that car. 2500s gave me a miserably long pedal tracking the M3 right away... Hated them - and they dusted more than the textars on the street. You have the answer with the PFC-08s for track work. I leave my 08s on the car during track season, but also put less than 1k non-track miles on the car during that timeframe. They eat rotors but the bite (even when cold on the street) and pedal feel is phenomenal.

What is this part? I was at the track and this flew into the passenger footwell on hard braking.

Isofix mount under the rear seat bench.

That's exactly right.

What deadening is that??

[Casa de Mesa]

S3diment , they are a couple of a yoga mats from Walmart cut to fit. They are temporary until I replace the solid differential bushings I stupidly installed. They are light enough to not make a weight impact really, but cutdown on the diff whine from the solid bushings. Works pretty good. Not spectacular, but get rid of enough to of the high pitch whine that drives me nuts.

When pulling the motor and you already have the intake
manifold off…

Does it make more sense to pull the harness with the motor or without?

Or said another way, should I disconnect all the sensors from the motor or pull the main harness disconnect from the DME?

From memory there isn't an easy way to bulk disconnect the main harness from the dme. Leave the harness box peice all in place and disconnected everything from the motor is how I did it.

When doing rod bearings, do you perform the triple turn torque sequence to check clearance with plastigauge, undo bolts, apply assembly lube, then repeat the entire fastening sequence for final assembly?

Also, should the rod bolts have assembly lube on them the entire process?

I disconnected the main motor harness at the DME and left it attached to the motor. However, I removed the O2 sensor and camshaft sensor wiring from the top of the motor. Should be able to lay these on top of the DME if memory serves me correct.

Look at the pics in my build thread for reference, both for removal and install. You'll see the main harness attached to the motor for both. However, in some regards this is personal preference as to which path you choose.

Yeah fair enough. I guess it depends on the extent that you are disassembling everything else. In my case I was pulling the motor to rebuild and everything else was going to be more or less undisturbed so it made more sense to disconnect each connector. Helped when putting everything back together as well.
