So the brakes on my 20yo CRX HF (yeah, an '88) are a bit worn out. Already had to replace the master cylinder, so I took the chance and put the integra/legend/prelude one in. But, my rotors and pads are getting old too, I was wondering if the SI front brakes, rotors (from like 9" HF to 9.5" SI) and calipers would be worth it. I've found remanufactured parts for dirt cheap and in looking up part numbers and prices, whats the difference between 88-89 SI and 90-91 SI front brakes? As far as I know everything is swappable but the 90-91 are more expensive and have different part numbers, but when looking at rotor sizes, both say 9.5". Also, part of this swap would be SS brake lines, and eventually rear discs, but the drums will do for now. Not a track car, just a gas-saving daily that I'd like to be able to stop well in. P.S. First post!
