Back in the days, I did produce a few rotors that were better than the competition. But as shipping them was too problematic, I stopped.

6 piston radial calipers at the front and 4 pistons lug mounted at the rear. Both calipers using extra thick 0.8"/20mm brake pads. This is more brake than even the good old euro e28 M5 which had 286hp and was heavier than the e30.Brake harder. Go faster. No shit.

I’m running the Wilwood kit Silver Mine Motors offers. I only have the front at the moment, the rear setup is on hold for a couple of weeks on their end I guess they’re behind on the caliper brackets. 290mm diameter 22mm thick rotors 4 piston wilwood calipers, braided lines and brackets. I also have the condor plates for brake cooling ducts. Pretty solid for ~$700

Here's another data point:
Enkei RPF1
15x8 et 28, 75mm hub bore
Would need a 20mm spacer to clear 300x32 kit. Ouch. Guess that rules that out, I don't think I want a +8 effective offset.
Going to keep hunting for a 15x8 4x100 wheel with high offset. I would really rather not make custom wheels.'90 325is + S52

Is there a good rear kit these days to complement the massive 4 piston wilwood/corrado front setup? I run a 25mm master cylinder (ATE) and currently running rear calipers from a nissan 300zx and rear discs from a toyota ma60 celica supra. Dunno if my rebuilt calipers are just not great, or if I really goofed on the bias math, but the rears just don't seem to bite as hard as they should. There're many miles of driving on the setup including a handful of autocross and track days and rear discs still show cross hatching! I have a wilwood bias valve fully opened and ABS still plumbed in.
Caliper sizes
Front: x4 piston 1.380"
Rear: x2 opposing piston 1.5"
MC size
25mm front/rear
Edit: ran all the parameters through a brake bias calculator and came up with a good number... (https://www.tceperformanceproducts.com/bias-calculator/) so I am not sure if at this point the actual braking performance of the car is hindered by some mechanical aspect (poor rebuilt rear calipers, bias valve, corroded ABS), or it's actually working properly and I am expecting too much, or I don't know how to use a bias calculator and my actual bias is screwed
Leg input in pounds: 60 Master cylinder diameter: 0.98" (25mm) Front line PSI (un boosted): 525.724 Front caliper pist dia 1: 1.38" Front caliper pist dia 2: 1.38" Front caliper pist dia 3: 0 Front caliper pist dia 4: 0 Total front piston area *: 2.991" Front pad Cf: 0.4 Front rotor diameter: 11.02" (280mm) Front pad radial hieght **: 2.21" Front Rotor Torque In.lbs.: 2772 Rear line PSI (un boosted): 525.7 Rear caliper pist dia 1: 1.5" Rear caliper pist dia 2: 0 Rear caliper pist dia 3: 0 Total rear piston area*: 1.767" Rear pad Cf: 0.4 Rear rotor diameter: 10.46" Rear pad radial height: 1.25" Rear rotor torque In. lbs.: 1711 Percentage of front Bias: 61% Last edited by Sh3rpak!ng; 10-20-2020, 10:35 AM.

Fits also with 15" wheels:
If someone needs, I have CAD files of the adapters here: https://drive.google.com/drive/folde...Hq?usp=sharing

I bled my Wilwood RPI calipers and slotted Wilwood rotors and new Wilwood pads they are 4 piston calipers anodized in purple, can't find any like it with a google image search. It is definitely worth posting a picture of.
The calipers have about a 2mm gap from the inside of my 16", 4x100, Azev rims, no spacers
Shocks are bilisteins, springs are IE, yet to install my new sway bars front and rear adjustable, rear shock mounts are aluminum,
She's at the alignment shop now, on standby waiting for someone to miss their appointment.
Im searching around for alignment specs at the moment.
Can someone please shoot me a link to some proper alignment specs for my setup, button willow this weekend?
