Toyota brake upgrade clearance

[AZDatsun]

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)

Yup, just grind off what you need to, it won't hurt the caliper any.

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.

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.

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.

Sure, a couple of millimeters won't hurt anything.

Nice work!![emoji106][emoji106]

No back plate?

Not really needed.  I don't run them on my race car.

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.

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 ?

Mine don't have a lot of clearance, but it's more than zero.

[AZDatsun]

Yes they are stamped s12w on them 
 

I purchased the following from rock auto.  Are these the right rotors?
