I recently snapped my frame in half and had to buy a new one. It snapped in first gear, how should i limit this from happening again?

 

What were you doing when you broke it? I assume launching the car? Weak/broken motor and diff mounts can cause too much slop in the drivetrain and cause other components such as the ppf to break. Poly mounts and trans brace help. Also, when replacing the ppf make sure it is properly aligned and torqued in the correct sequence. Can't tell you how many people don't do this. You can also reinforce the ppf by welding some square steel stock in key areas. I have done this many times.

 

Great info! I'm putting mine back on sometime soon and didn't even think about this. Does the FSM cover the appropriate torquing sequence?

 

Banzai Racing Transmission Crossmember and Diff Brace, healthy motor mounts (stock or Poly) same for the diff mounts. This is the setup I have in my 750rwhp 20B rolling on 335s, have not broke or cracked a PPF yet.

Yes the FSM gives you the proper sequence.
