sexy struts. very nice setup. are the discs solid or vented?
funny how aussies seem to call 4 pot calipers 4 spots? do you guys call a four cylinder engine a four spot too?

In america we call them four-piston

wow, thats insane you better watch out not to roll your car...frontways like a sumersault . you must have deep pockets

im surprised that you stuck with the same stud pattern, why?

Building it as a vintage road race car. That's why I couldn't use a 4 pot caliper. (These are only $90 bucks apiece though!) I'm using American racing Libra wheels, 13x7's.

wow!!!! that a nice bit of hardware! have you ot these in the car and tested them yet? how well do the pull you up?

Haven't tried em yet! Rob Walker, who has one of the fastest road race 1200's around, told me that the stock 1200 calipers with good pads stops his race car easily. These as stiffer, with a much bigger diameter disc for better lever action so they should work great without adding any unsprung weight! We'll see though when I get that car on the track!

UPDATE! I finally got these struts on the car! Wow is all I can say! The pedal is rock hard and the car stops ridiculously fast! I haven't done any measured stops yet but the feel is outstanding. Plus the huge holes in the disc make this great electric motor hum while hard braking! The 250 LB. springs were way too stiff for street, maybe alright for the track. I dropped down to 175 for now which is working great!

mmmm yeah 250lb springs would knock your molers out after about 6 miles on the 405. Rob Walker would know 1200's for sure since he's been racing the them for about 35 years. I guess I never quite got the right pads in the stock calipers as they always seemed a tad weak.

Tom.

to my surprise and what will surprise many others is that willwood calipers are not expensive for what they are

man these look sweet as.... ive got Baz from datsport.com making me up some custom R31 struts and disks for my 1200... they should do a good job of stopping

YEP! Only $90. American for the Dynapro single each!

Are four spot calipers availabe too suit the caliper mounting and that disc? Can you give us part numbers? Just finished my coilovers and need a solution for brakes. I'd like too try a setup like yours but run 4 spots if possible. Also want to stay under 13" wheels.

looks sexy but i have to wonder what the area of the pad is compared to the area of those big holes. when the hole is at the centre of the pad you would be reducing the contact area by 50% it appears???

They're 47mm inside, 50mm outside. It pretty much slip fit over the 1200 tube. Haven't run it yet so I can't comment on the spring rate...
