V8R Stoptech 11.75" BBK
#46
I ran my first race with the new V8R 11.75 STR42's last month. I finally have the pedal I had always dreamed of in my Miata. I could not be happier with the setup! When combined with a 1" master and sport rears the modulation was perfect. Pad life is looking good too. I got about 5 sessions on the setup and still have a ton of pad left. Pad thickness is similar to Dynapro radial.
The new rears look great!

Oh yeah, I should probably post some pics
V8R/Stoptech STR21 rear caliper. Race only setup (no e-brake). Fits over Sport rotor, or in my case, V8R's 2pc rotors that are made to match factory Sport rotor dimensions.
Pads are PFC 11's to match the fronts.

Some wheels won't fit the 11.75 without spacers so it's good to have the smaller option. And I certainly couldn't say 11.75 are proven over 11" when an optimized system is always the smallest possible setup that will work for the hardest conditions it will see. You want smaller and lighter whenever possible, agree? I know guys that change calipers and/or rotors on all four wheels because of a particular track where a larger rotor/caliper is not needed for thermal management.
9mm larger radial difference is noise level for thermal capacity and brake torque (if ring weights are the same) so it must come down to vane design & cooling efficiency if there is ANY difference between these two options.
