Hi guys
I have searched and searched for an answer to my problem, I cannot find a correct answer so here is my problem
I have a 93 civic si hb with an itr motor it is a track only car, after switching from my B16a to the itr I found that my regular integra front brakes were not stopping the car, safely. So I upgraded the front brakes to legend twin pot with prelude re drilled rotors and hawk blues, and a 1" m/c with a manual brake booster (the slim one). The rear brakes are stock 93 civic si calipers with hawk hps pads. When I brake really late in a fast corner from 200+km I cannot get the car slowed safely it un weights and spins sending me off the track. the previous regular integra setup allowed me to brake late and not spin.

So my question is should I

a. change the rear brake setup to a rsx/ep3 setup? (or something similar legend)

b. change the prop valve? is an integra prop valve different than a civic? is and itr prop valve different than a reg integra?

c. install a adjustable prop valve? with or without upgrading the rear brake setup?

I hope I have provided enough info.

 

sounds like your rear brakes are bitting hard, try oem pads in the rear. since your car is a si it should already have the proper prop valve but i could be wrong
