QUOTE(wndsrfr @ Jul 15 2015, 07:02 PM)  OK, Here's my Wilwood conversion & I love it. Initial installation was with Stoptech rotors & I used washers to center the caliper, worked fine. Check out the difference in the pad sizes vs. "A" calipers--massive! However, with those rotors I found that the Wilwoods pads don't sweep the entire disc, leaving about 1/2 inch around the inside next to the hub. They developed radial cracks immediately from the uneven thermal stress leaving me a bit uncomfortable about staying with those stock dimension rotors. So...Installed Wilwood's rotors using the hat sold by Rebel Racing & fabricated a 3/8 inch aluminum bracket to center the pads on the rotor disc radially and axially. Saved a bit more weight and better yet, the replacement rotors are like $30 from Summit Racing--can't beat that. BTW, Here's my Porterfield R4 pads after 3 DE events totalling about 700 miles on track and maybe another 300 miles street driving. The outers have worn more than the inners and when they're pulled there's a noticeable fromt to back taper. Doesn't affect the braking at all--frankly, I'm still overbraking nearly everywhere--just breathing on these monsters takes a lot of momentum out of a 2000 pound car! Be careful about jumping on 6 piston units that you size everything properly front to rear and to suit the ratio with the M/C....My setup is using Wilwood 120-11131 with 1.62 inch pistons to go with "M" calipers on the rear and 23mm M/C. High hard pedal & could probably work better with 19mm M/C....ymmv. Impressive! Did you have the adapters CNC'ed or how exactly did you make the rotor adapters? Very very trick setup! |

I will now agree with Mike, started as a small idea, thanks to Scott, grew with the beginning of the thread, and now has been driven deep into center field by John's impressive installation.
Sometimes I wonder why I get onto this forum, time to earmark funds in the budget! |

I made the caliper adapters by old school measuring twice, cutting once & drilling with my lame old bench top drill press. Should really do a slicker job some day.
The rotor "hats" that mount the rotors to the hubs came from Rebel Racing & hardened bolts & stamped lock nuts from McmasterCarr. Bought a box of 100 each since they are single use in my book. |
