Big HP FD Power plant frame Question?
 

WHo has a Mazda speed PPF and does it work? I broke my stock one when the car was still stock and I don't believe the Mazdaspeed one is gonna work when the car is done. I want to make over 600hp and I will do some drag racing and road racing. Is there another fix? Beside the Mazdaspeed PPF?

Why not gusset a stock one? That is what we do with TII rear subframes. It is cheap, perfect fitment, and strog. Plus since you broke one, you know its weakness already. Carl
