Help me choose a BBK

OP I have a Silvermine kit. It is very impressive for the money. 6 pot front 4 pot rear. I used the stock booster and installed an adjustable bias valve. The braking power is incredible. For comparison to your goals my car makes 300 wheel hp. This kit provides more than enough braking power for my setup. The install is fairly straightforward however you do have to trim the factory splash shields both front and rear. They also fit behind a 15 inch wheel. Best of luck in your decision.

I'm pretty amazed to see the 6-piston fit so cleaning inside 15" wheels. Are you running spacers?

(I probably don't need 6-piston for my S52-swap, but...). Was the adjustable bias valve from Wilwood also?

The bias valve comes with the kit and is also made by wilwood. Get the 6 piston fronts. You wont regret it. I can hang myself in my seatbelt should I decide. There are spacers behind the wheels. Et 12 front and rear.

I know it's not your kit, but do you think the 6-piston will fit behind 15" Ronal LS wheels? With what size spacers?

I'm trying not to bite off replacing the rear calipers too, so wondering if the 4-piston will be enough. I don't super-thrash the car, but I feel like the S52 is giving the current setup more than it likes (at least with my driving...). I have all the stuff to rebuild a full-ATE setup (new pistons, etc) and new rotors/pads, but the cost of the 4-piston setup is close enough that I could rebuild the ATE stuff, give it a nice coat of paint and sell if tor a few bucks to help defray the cost of the Silvermine setup a bit...

if its a street car 6 piston is not needed and no tangible benefit
