Posted September 6, 20213 yr comment_628156 Anyone have to shave down the caliper fins? I have 15x7 konig rewind and the fin on those calipers are rubbing. I have 1989 Toyota 4Runner v6 calipers nugeon 9701550A (97-01550A) and 9701550B (97-01550B) Link to comment https://www.classiczcars.com/forums/topic/65796-toyota-brake-upgrade-clearance/ Share on other sites More sharing options...
September 6, 20213 yr comment_628170 Yup, just grind off what you need to, it won't hurt the caliper any. Link to comment https://www.classiczcars.com/forums/topic/65796-toyota-brake-upgrade-clearance/#findComment-628170 Share on other sites More sharing options...
September 6, 20213 yr comment_628177 Good advice above.I had to do that to fit my 14” rims and took off a full 5mm off the fins. The way I figure it is that those callipers were designed to stop a two tonne truck and my Z will never stress them enough to need the fins.

September 7, 20213 yr comment_628191 Yes, the Rewinds don't come close to fitting over the S12 + W calipers. They only need to be ground down at the inner corner, the rest of the fins can stay in place. I also needed to install longer studs to get proper thread engagement on the Rewinds. Make sure you have enough threads engaged.

September 7, 20213 yr Author comment_628206 Thank you that worked I took a flap disk to it and now I got rim clearance. Now my other clearance issue is the rotor to caliper. It’s equally tight on both sides should I file the caliper down slightly to get a little wiggle room. It even rubs a tiny bit on the caliper.

September 7, 20213 yr comment_628207 Sure, a couple of millimeters won't hurt anything. Link to comment https://www.classiczcars.com/forums/topic/65796-toyota-brake-upgrade-clearance/#findComment-628207 Share on other sites More sharing options...

Are those calipers for solid rotors, or vented rotors? I think there are two versions, aren’t there? It doesn’t look like you have the brake pads in there.

September 14, 20213 yr comment_628503 I was wondering the same thing Racer. My Toyota calipers have way more rotor (Z31 vented) clearance than he's showing there. Are those calipers S12/W ?
