Anyone using a wilwood manual master cylinder

Ok the wilwood is coming off and going a different route. Car has MBM discs from Mancini on the front. The new 8 3/4 rear has GM metric discs on it . On Monday I am talking to Mancini and dr diff. Most likely go with dr diff pedal ratio was figured last night and is 6 to 1

where the rear disk also from MBM ?

what did MBM suggest for a master.

When going rear disk you need to have a proven matched setup with your front brakes and prices master cylinder setup.

worth extra money to go with dr diff. For the time, effort and parts you’ve thrown at this Dr Diff would put you met ahead.

btw, did you buy that disk rear end from FL or NY ?
