Brake upgrade for HPDE

[Bimmerman535i]

I have the 4 wheel 332x32 Stoptech kit, with the RaceMax floating hardware (addresses pad knockback).

Zero complaints. I don't have to think about brakes anymore. I don't run ducting but I don't need to with my local tracks, plus I'm quite skilled at rubbing holes in the hoses.

I went back and forth on this for awhile and just decided on the M Performance Brembo kit from Turner Motorsport. It'll be a bit before I get them installed and get any feedback but I felt it was a decent step up from OEM 330Ci fronts and without the associated costs of a complete aftermarket BBK and possible proprietary consumables. Sticking with OEM M3 rear setup and plan to balance the F/R braking with pad selection. If it matters I'll be on 200TW RS4s and expect to make about 425rwhp. Under 3000 pounds without driver.

Nice setup overall. I'm sure it will be enjoyable.

Got a link for that?

My take on the kit offered by Wilwood. The rotors are great. They are heavy and will accept huge heat bursts, and have a ton of cooling vanes to evacuate that heat. The rest is junk. Hats are fixed and not floating. Calipers are the narrow model which only accept the thinner 16mm brake pad. Also, it is painted (not anodized or zinc bathed) and paint traps heat and dirt. And looking at the number of shims that come with the radial mounts, it is most like a generic mount that fits many chassis.
Is the StopTech kit better? Not necessarely as the calipers most likely have aluminum pistons, where stainless or titanium is needed to act as thermal barriers between the hot brake pads and the brake fluid.
As for the ECS kit, you're not really improving much.

I would listen to this guy. He knows brakes.

I suggest looking at Essex's AP Racing BBKs
And change the rear sliding caliper to a fixed one on OEM rotors.

Which rear fixed caliper would you recommend?

I apologize in advance for the self promotion, but it seems I am the only source for such kit on the e36 and e46 chassis (Fixed four piston calipers on OEM ear discs).

You'll need Wilwood part # 120-13234 as well as Massive's radial mounts kit.
The Wilwood calipers have the exact same piston area as the OEM sliding caliper. Meaning your brake bias stays as original
It is even possible to fit 328mm e46 M3 rear discs (e36 M3's rotors are 312mm) by adding 6mm thick stepped shims between the radial mount and the caliper.

Benefits are as follows
- A stiffer caliper with no play.
- Slightly stiffer brake pedal
- Better modulation
- 30 to 40% cheaper brake pads for the exact same compound from the same manufacturer.
- Depending on your front BBK, you could even run the same pad shape/compound on both axles.

Or if you want to keep 16" rims
