    Sigh, still waiting for 15x9 jongbloed wheels info (cad drawings ) to become available before ordering one of your sport kits . Money set aside specifically for the kit :)

      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.
      Thanks so much for clarifying. I can't remember why I thought that or where I thought I had come across that info. I will very likely be ordering from you once I decide exactly what I want.

            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.

              e38 brembo brake saddles that are made narrower for 22mm brake disc, mini countryman 294mm brake discs with 2mm spacer behind and enlarged center hole. And then custom adapter for the e38 saddles:






              Fits also with 15" wheels:

                part number 34311156643 from ATE

                i had a 25mm/23mm before but I don’t know the par number

                  For what it’s worth I’ve tried both , 300x22 and 300x32 against my TRM 15x8 and 300x32 needs a bigger spacer than I want to run. 300x22 is close, clears with 5mm .
                  Out of curiosity (I have the same wheels), what size spacer did the 300x32 need to clear?

                    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.

                          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
