Poor fit and function
After using the style from smileys, this one was a disappointment and a disaster. Smileys braket is 1/4 steel. It was bend in an accident and i tried this one. Well, it is made from much lighter steel and poorly shaped. Hard to install, pads take modification to fit and caliper is hard to get on and off. After 6 laps it failed under hard braking on a tacky track. Replaced with the smiley's style and now it works flawless. Lots of great products to get from speedway. This isn't one of them.

Will this bracket work with your #91031046 E-brake metric caliper? I am planning to set up one of your # 91048323 GN rear axles for street use.

Hi I really like the look of this bracket I want to use it on my ford 8.8 axle to fit disc in the rear since my explorer disc set up won't fit. Do you think it can fit a 3.25 axle tube? And can it be used with an 11.25 rotor?
