RacingBrake needs your input asap re caliper/wheel clearance
warren is in the late stages of finalizing a front/rear brake upgrade (see FD... new brake options thread) for the FD which will use the OEM calipers, E brake and will greatly improve braking performance.
he needs your input as to aftermarket wheels and caliper clearance versus the OEM wheel.............
please post your experience as to any clearance issues w aftermarket wheels and calipers.
if you have been following this thread you may remember that after developing the RX8 one of the owners ran into a clearance problem w a set of Enkies. Warren made a deeper hub and changed the caliper mounting bracket to accomodate the wheel.
here's a recount and picture:

ideally, it would be great to sidestep the problem so please do post any info you might have on this matter.
thanks,
howard coleman

I know that if the disc size goes beyond a certain point that I will have problems with caliper clearance with my 17" FM-5 Fikse wheels. It's been the stumbling block that has prevented me from getting a BBK kit such as Stoptech or Brembo. With the stock calipers, I can try and measure to see how far the caliper can go before clearance becomes an issue; the Fikse wheels' thick spoke curves a bit inward just at the rim junction, which will probably be the biggest clearance problem.

how about estimating the clearance you have between the inner wheel and caliper and referencing it to the approx tightest spot on the caliper.

I say build the best possible kit and if manipulating the hat and bracket don't cause a problem then keep it off the wheel. Those who really care to have the best brake kit will buy the wheel that fits it.
With that said the most popular road race wheel for the FD is the classic CCW 18" wheel with a 50mm plus offset and you could run into problems with a fat caliper so I would start there. CCW would have all the measurements needed.

^^ Agreed. Soliciting input from folks to get estimated clearance #s based upon their current wheel of choice seems to me to be a fruitless endeavor. Too many different wheels and very imprecise measurements.

Everytime i've tested the stock brakes- or rather whatever i have on the car since i bought it this way: Stock caliper, cross drilled slotted rotor, unknown pads. -i've been pleasantly surprised. Poor surface traction, emergency/panic, etc.
I can't imagine having better brakes on stock size tires.

When I had Fikse's, I downloaded their template, and it JUST barely scraped the inside of the wheel. Whatever dimention the ST template is, is the dimention of the Fikse wheel. I seem to remember 42 mm being something... or 24 mm maybe?

With that said, I don't see a big compromise in performance from using a deeper hat for better wheel compatibility. A slight increase in weight that allows the kit to work with most any wheel is a good move for my needs.
But I am a cheapskate...
