Has anyone tried to fit these under 15x9 +36 TRM C3M?

Needs 5mm spacer and then it's gravy.

That Stoptech caliper looks oh so sexy!

I'll second that.
I just need a car worthy and the spare pocket change.
Is there ever going to be a chance of an e-brake option on the rear?

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.

I've used a 1/4 turn ball valve with pretty good success as a parking brake

oh, that's sexy

Front install completed. Four wheel kit installed, but this one is with the 11" rotor.. Now all I need is to reinstall the motor so I can actually use the brakes.

Nice pic of tiny 11" rotors. This is race prepped section where 11.75" rotors have proven to be the best for track usage. Now back to V8R/Stoptech awesome sauce.

Lol. Tough room.

Lmao, I was waiting for it

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.

Fixed my previous posts' images that had gone down.

Pics of the rear V8R/Stoptech STR21 kit to compliment the front:

Maybe I'm wrong but my math is usually pretty good, wouldn't the difference in radius be closer to 9.5mm

Wouldn't it be more like 9.525mm? :giggle:

You are right - corrected in my post, but still not enough to impact brake torque or thermal mass significantly.
