4runner calipers on 6thgen, caliper up grade Options

[99gt3sge]

I wanted to ask if anyone has successfully mounted these calipers, i read it on one of the threads but i didn't find out if they finished it. i bought a set of calipers and lined them to my knuckle but the bolt holes don't line up 100% it looks like i would have to drill the hole a bit more and thread the knuckle. aside from that the 4runner calipers wont accept a rotor over 21mm according to the specs. i want to know if any one actually mounted those on a 6thgen or it's just speculation. i have already tried a vw rotor but no dice. i'm going to try a 04 sti rotor which is 5/100 and it looks it will sit the rotor further back in and might work with the caliper. i want to know if it's necessary to trim the caliper mounting points.

There is also a reasonable size difference between the two calipers. It seems that the frs rotors could fit. Its a matter of how hard it is to do so. WRX rotors from 2005 could also work


Answered my own question. The above calipers are for the 16" Wheeled 4Runner (2.7L LE and 3.4L V6)

As you can perhaps see they are somewhat smaller in size, and the tabs are definitely shorter on the 15" version. of the calipers. Side by side, I couldn't see any noticeable diference in the caliper piston diameter.

All I've left to try is actually testing both rotor and caliper on the car to confirm fitment.

I'm not trying to reinvent the wheel, but 4runner calipers are much more abundant and much less expensive than GT4 calipers, regardless of the extra weight and necessary modification to fit. It's DIY alternative to a big brake kit vs using GT-4 calipers.
