Will our stock brake booster be sufficient for an upgraded set up ( say.... 6 piston calipers)???

I'm sorry to say, but I don't know your name. Can you give me that as well?

Also, do you want the PS rack for a gear change evaluation as well?

Todd

The brake booster will be more than sufficient, I have to look into the capacity of the SVX master cylinder though. However I imagine it's just fine for what's needed as it works with the WRX/STi units very well.


If you'd like to ship that as well and don't mind me tearing it apart with the intent that it "may" not go back together that would help a good deal in this matter. The caliper bracket will be very easy for me to get what I need from it and ship it right back to you. Your assistance with this is greatly appreciated :)

Adam,
I think Todd needs your last name to put on the shipping address;):lol:

So would you be making just an adaptor and selling that alone or would you assemble an entire BBK for us? Also, what about the rears brakes?

Duuur me......I'm tired :)

Wilwood = just adapter.
Brembo = adapter and/or kit if wanted.

Rears would all depend on what type of rotors I can find to work with the e-brake setup on your car. Rotor thickness and offset play a big role in that area back there with compatibility with the Brembo calipers

Another interesting wrinkle at the rear is the dual nature of the rear brakes, with the drum type parking brake inside the "hat"

Check the wilwood 4 pot rear upgrades for the Sti's they use a parking brake drum design just like our cars.

Exactly, however the rotor thickness the Wilwood calipers use compared to what the Porsche brembo's use is quite different.

All of the cars I've ever made rear Porsche Brembo setups for have had the OEM e-brake setups removed in favor of a small clamp style e-brake caliper installed in conjunction with the main caliper. Ends up lighter in most cases anyway...

I have also heard that our rear calipers have more than enough clamping force.... But its not force I am looking at it is surface area, I cannot remember if the pads and/or rotor was larger. Reason i looked into this is my last track day I experienced some serious fade due to the shear weight of the car.

I have been asking around on NASIOC about BBK manufactuerers and am getting a consensus that StopTech is probably the better all around choice... Any opinions on that?

Corvette?
 

I believe as far back as 1979 that the Corvette used a similar parking brake setup with vented rear rotors. Might be worth a look-see. :)

great stuff guys !!!

im intrested in the brake upgrade as well, let me know the final price and where to source the calipers

With all of this work one thing has been neglected..... What about the 6 piston Willwood set up that Dayle has? Has he already developed a bracket to make the calipers work?
