So I have an 83 cutlass . Ls powered , supercharged. I put the wilwood 6 piston brake kit on the front. 4 piston kit on the back . Swapped prop valve for a 4wheel disc . Car stops good, but it seems most of the braking is in the front . It’s really noticeable at the track . Car traps 130 . Slowing down seems like only the front is working . Will an adjustable prop valve fix this ? Or should I just swap out the master at the same time ? Thanks

Did you use the stock master cylinder for rear drums with this install? If so I would get the suggested MC from Wilwood. When you install that you can dial in your bias with the proportioning valve. I have the same type of kit you have on my 86 Chevrolet C10 and my 76 Chevrolet Laguna S3. This is how my Laguna's set up looks. You have a fast car so you need some strong brakes. Good luck.
