Hey I'm looking at a rear disc swap for my car from a 94 Acura Integra GSR with ABS. I know I dont have ABS but apparently it will still work...however.
Here are the problems I forsee
1. Mechanical Proportioning(not valve) Will the rear discs be bigger than my front and *** drag
2. Need a new brake master cylinder or new seal...or bore mine
3. B rake booster or literal 4040 proportioning valve.

Can anyone tell me more about this? I've found many posts about these rear disc swaps but none that show the literal proportion of rotor size from front to back. Any help would be great. Thanks for the time

 

When I did the rear conversion on my 92 hatch, I left the prop valve, master cylinder, and brake booster stock. Braked just fine. The rear discs are .1" smaller than the stock front.
