I am using the Trail gear kit, and am down to the brakes. What calipers do you use with the trail gear kit? I was thinking that you used the IFS, but the rotor is too far away from the backing plate for the calipers to go on. I think that I need to use the IFS rotors? THey are deaper. What do you have to say?

 

Might want to call or message TG directly...

... but my similar Marlin kit used the included LC rotors and the IFS calipers. Did your TG kit come with rotors? Would it be possible you used the IFS hubs or perhaps have your wheel spacers in the wrong position?

Maybe a few pics will give some clues.

 

I used waggy vented rotors
