I am looking at a wrecked 93 Del Sol Si that is local to me that has all the Rear suspenion still intact. I wanted to know if those rear brakes will bolt up to the 88 CRX and I also wanted to know if the Master Cylinder, Brake Booster and Proptioning Valve would be good to get as well. I searched but could not find an exzact answer. Thanks for all the help.

 

RTA = Good
Brake MC + Booster = Why, aren't they ABS?
Proportioning valve = Again, isn't it for ABS?

 

get the trailing arms, then find a ef si mc and prop valve

 

If the Del Sol has a booster with a 230v or 260v tag on it then pick it and the master cylinder also. It is a great upgrade.
