I want to do the rear disc conversion on my 98 Civic Hx. I will be getting a 94 Del Sol Si as a donor car for all the parts. I know I need to just swap out the complete rear trailing arms, e brake cable and brake lines. I am not sure on the master cylinder, booster and proportioning valve. I checked the Honda part numbers and found; 98 Hx and 99 Si use same proportioning valve and master cylinder. So then does that mean I dont need to swap the master and proportioning valve cause the Si has rear discs and uses the the same master and proportioning valve as the HX???

im pretty sure you dont have to just swap trailing arms..

when i did mine the doner car was a 95 interga i have a 95 civic dx all i used was the trailing arm assembly and the ebrake cable and brake lines and they work fine with my stock brake booster and proportioning valve actually i dont even think i used the brake lines i think i used my stock ones

Rear disc swap from the Del Sol is done and both cars and rolling and running. LOL you dont see many Del Sol Si's with rear drums, it still stops great though. For those interested I swapped over the complete rear trailing arm. You need to use the rear dics brake lines. The Del Sol E brake cable will not work, you need 94-01 Integra for 92-00 Civic Coupes. I did find that one brake on each of the teg brake cables would not quite fit on my Civic. No problem I just did removed the mount bracket from the cable. Then it fit and lined up perfect. My brakes feel a bit weak and they always have. I think I need a new master cylinder. Might as well get one for a 99-00 Si or a GSR
