hey i have a 99 civic 4 door and was thinking of doing the gsr rear brake swap on it, and i wonder if peple have done this and tell me about your results. also how much will it cost.

 

Please search...
There are hundreds upon hundreds of threads on this same topic: heres just one out of the 300+ results I got from a quick search

It will cost you about $200+

oh, and all rear discs are the same - gsr isnt special at all (even in the front theyre the same as ls/gs)

 

I've done it, it cost me over $300 since I live in Hawaii. I had to buy new ebrake cables, rotors, and pads.

 

check the FAQ at the top as well. Tons of info there. And... well, bling bling... Rear drums do the job.
