Rear Disc brake
« on: November 18, 2016 - 03:52:44 PM »
Anyone has experience with the rear disc brake kit from Mancini Racing? It looks different from the one offers by Dr. Diff which is still out of stock (for a long time).

The smaller Dr Diff kit is out of stock but the larger one isn't.

The bigger rear brake is recommended to match the 13" front. I plan to upgrade to the 11.9" front brake only. Seems that no one has done 13" front with the 17" YO Rallye wheel.

I'm patiently waiting for the Dr Diff 10.75 rear disc setup... so that i can still have the option of running 15" + 16" rims.
Autocross/road racers go in deeper... and come out harder!

Wilwood has a few 15"/16" rear disc options. I got good pricing on my front/rear Wilwoods from MCBParts.com this week, a few hundred off overall vs Summit.

Do you have the wheels to measure from?

I have Cass' 11.7" rear kit, would recommend.

These measurements are the front 17" by 8" YO Rallye wheel. Not exact but looks like around 14.75" at the hub and gradually increased to 15.5". Can someone check if Dr. Diff 13" Cobra front kit will fit?

The Dr Diff 10.75 rear disc setup is on back-order for a very long time ...

May be discontinued. I may go with the larger rear if the 13" front works out.
