With a 14-inch rotor and 6-piston calipers, this BBK will not fit under the 17x9 RPF1. This is the largest BBK on the site.07miata wrote:Brian, looks like this kit is finally available?

Re: 17x9 +49 clear BBK?
The regular 12.88 inch will easily fit most 17x9 thanks to very narrow six piston caliper on this kit.
Only the most radical track NC will need or want the 14 inch (we plan to run it on our NC LIGHT track toy).

Re: 17x9 +49 clear BBK?
It's a $265 upgrade for Thermlock pistons....and unless you have dedicated race car with 500+ hp I can't see the need. But if you are stuffing in a turbo V8 or otherwise doing that kind of build just ask us when you order and we can make the adjustment to the order and send a receipt by email. Yes, the easy rear setup for balance is RX8. The kit includes pads in their own little Wilwood pads box.... so that will give you the part number for future pad orders.07miata wrote:Brian, looks like this kit is finally available?

Some quick questions:
1. the description mentions this:
-For more aggressive race applications, calipers can be fitted with our exclusive Thermlock pistons which provide the most effective thermal barrier for minimizing heat transfer from the brake pads to the caliper body, seals, and fluid.
how do we order this kit with the piston option above?
2. are the stock RX8 rear calipers the best option for balancing out the rears?
3. does the kit explain what pad size to order in the future, if we want to use PorterField or Hawk or some other compound?
Thanks!

Re: 17x9 +49 clear BBK?
Brian,
What RX-8 parts do we need for the rear? OEM calipers and some RX-8 compatible rotors from your shop, I'd guess. Anything else?
The new kit should be a big interest to SR autocrossers, especially those running the RPF1s. I hope to place my order in the spring or summer.

The RX8 rear is a super easy install, you just need the calipers/pads and hats/rotors

Re: 17x9 +49 clear BBK?
Out of curiosity, what is the thickness of the spacer that comes with the 6 piston Wilwood kit, and would it require longer studs at all?
Re: 17x9 +49 clear BBK?
Thin little 3mm spacer that does not require longer studs.91 IMPULSE RS wrote:Out of curiosity, what is the thickness of the spacer that comes with the 6 piston Wilwood kit, and would it require longer studs at all?

Just to make sure, will the 12.88 kit clear the 17x9+45 RPF1 without the spacer? I can't run even the 3-mm spacer with 255 tires.Brian wrote:The regular 12.88 inch will easily fit most 17x9 thanks to very narrow six piston caliper on this kit.

Re: 17x9 +49 clear BBK?
Nope..
This Narrow 6 piston is about as narrow as multi-piston calipers get but the Enkei 17x9 RPF1 45mm wheel still needs 3mm spacer to fit with this kit.
I also checked our other problem child, the 45mm RPF1 18x9.5 and it clears by about 3mm....making it our only brake kit that will fit without spacers with that wheel.
