Actually we are working on a plate that extends from the swingarm brace, the 1/8" peice of ss inside the tunnel to the brake caliper, instead of the pins threading is like the OEM design from wilwood we are going to machine our own pins out of stainless and tig weld them to the plate, that way the pins are just resting in the holes in the side panel and get their strength from the inner plate.
Fortunately the design has very little side force or leverage on the pins as the caliper is mounted on both sides of the panel. Therefore the main concern is keeping the pins in place.
All the support for that caliper is on those two 1/8 '' treads going through the panel. It needs support on the outboard side of those pins.
I do note that since Frozen Moto( 7 yrs) you have never said you made a mistake.
This caliper is one of them. Wilwood pins and design are not at fault.
The bushings breaking in the rear strut is not the temperatures fault.
The idler wheel placement is not the track manufactures fault (the track was built to your specs)
The fit kits that did not fit
Ski saddle that bends
The ski is not your fault but you should have caught it.
Everyone screws up but just man up and admit your mistakes people will accept that. Fix the problems properly. So far most of your quick fixes(that I have dealt with) are not going to last.
