Hi, I was wondering if a set of gsR front calipers would fit my '93 Si of if I'd have to change the rotors as well. I pretty much got the whole suspension arm, but I got slotted rotors now, and I wouldn't wanna swap those out. I want to use the gsR calipers, but I wanna know if I can use the same rotors. thnx, l8r

 

Yes

 

I have a set of front power slot gsr rotor and stock calipers with porterfield R4S pads in my garage that want to get rid of. Let me know if you are interested. I'm in NY so you can come pick them up if you want.

 

you have to change the knuckles along with the rotors and calipers.

Knuckle swap from a Teg is about $150.

 

oh, I already have the knuckle, rotors and caliper, I just wanted to know if it was necessary to do the whole knuckle, or can just the calipers be used w/ my rotors.

 

swap the whole knuckle, bleed the brakes, get an alignment.

Best $150 upgrade I ever made!
