My rear calipers keep locking up, I have repl them twice now. Does anyone know if the 2g rear caliper will fit on the 1g in the rear?

What is the 20g record? I've put together a 20g auto car with a high compression motor from Boostin Performance and is tuned on E85 by Devin. Looking to go 10.5 any thoughts?

Hey guy I put a 2g auto trans in my 1g and welded the center diff. I got the Kiggy kit to adapt the the 2g to the 1g and i have everything align right. When I put it all together put the vehicle on the ground and the car wont roll at all!!! When all was apart everything was moving as it should...
