hey guys, i keep seeing all this talk about y tebo runs the rb5 axle.. he also runs aka wheels. these wheels like the proline wheels have a deeper hex molded into them. so if you run the rb6 front axle with these rims they rub the spindles carrier a little bit. i just dremel the wheel tio make it work with the 6 front axle, if yo measure the rb5 axle with the hex it is in fact the same measurement as the rb 6 one, so really its not changing anything on the car except know he he can run his sponsors rims with zero issues.
