I think I need to replace my PPF. I get the humping on the back when I take off on first, the car vibrate bad when I floor it, and the shifter moves around a bit but no shifting issues. I'm was wondering since the PPF is not really cheap if I could get a tranny and diff brace and this will fix the problem. I know adding this stuff will shake the feelings off my teeth but I don't really mind. Other thing I think it could be is the diff mounts and the guy that I got the car from said it could be the trailing arms. I haven't got the time to get under the car yet to investigate. I already got a new diff mounts but I'm waiting on a new fuel filter to do that while there.

 

could you take your PPF to a good welder have them fix it?

 

I would get under the car and find the crack. Take the PPF off and get a competent exhaust shop to weld the crack up. Its not hard to fix them. Thre crack will get worse no matter how much you brace it.

 

I didn't think about that. I guess I look to see if that's the problem. Thanx

 

Just get rid of it.....

 

^ then what?

 

and be fast..........

 

I've seen PPF's in the classifieds for $100-$150. I got mine used from a member here for $120 shipped.

Well I took a look under the car and the ppf and the diff. mount seem to be fine to me. I will post some pics off the diif mounts.The other thing I can think of is the engine/tranny mounts.

 

any opinions?

Get a Mazdaspeed PPF. I just ordered one through Bulletproof Automotive.

Well the problem is not the PPF. That's what I though at first. And diff. mount look ok to me. I also notice something weird. When I go WOT on 1st and 2nd I get some minor vibration from the tunnel and I also get the feeling like my tranny is moving around, so that's why I'm shooting for engine mounts but still I don't see why it would make the humping noice.

 

found out what it is came out to be the diff mounts. I took a pry bar and it move around pretty easy/ I can actually move it with my hand.
