Sledgehammer bang shifting hard out of 1st gear
Whenever I wind the car out in 1st and shift second hard, something in the rear bangs like I just got hit with a sledgehammer or got rear-ended. The car has a lot of slop off and on the gas in the drivetrain. Other than that, I don't have any problems driving the car. No trans syncro issues, and I replaced a leaking RR shock with 4 new Tokico's. What could it be? Did I blow the rear differential mounts?

Same Noise
I have the same noise, when I shift. Sounds like a huge clunk.
Is there and after market PPF that would be stronger? Can you weld or strengthen the stock one?

Not a backfire, just a feeling like I was just rear-ended. I get a little bit of popping from the exhaust, but that is only at low rpm.
If it is the PPF, I'll probably get the MazdaSpeed one from:

Does anyone have it cheaper?

Yeh, I contacted him. His price was much cheaper. Just wish I'd have time to get under this thing and figure out what it is. I already know the toe links are bad, but I doubt this is the problem.

I can't figure out what is wrong with this thing. The only thing I can find is that the toe links are bad and there is a lot of play in the ring-and-pinion. I see that I have a sub frame connector(pipe) from the rear subframe to just fore the u-joint. Is there supposed to be a matching one on the right side? Looks to have the same bolt holes for it.

Just curious if you ever found the problem. I have the exact same symptoms and was searching for answers. Haven't crawled under the car yet to look for anything since I haven't had the car long and don't even know what to look for!
If it turns out to be the diff mounts, should they be replaced with stock ones? I know there's tougher ones out there, and even heard of solid ones, but it seems like Mazda made them soft for a reason. Is it to protect things like the gears and u-joints, or just to smooth out rough shifts, or they were cheaper, or what?
Thanks for any advice...

what kind of clutch do you have?
since the first day i got a racing clutch (3 puck) in my FD, the same noise started. almost everytime i shift, CLUNK!!! it will sound like its comming from LSD area.
as fellow members mentioned already, it could be your PPF. just check visually.
just FYI, i regret that ive got 3-puck clutch. it is just too harsh too drive on the street. (not impossible though ) im planning to replace it with ACT SS clutch when i get my tranny rebuilt.

Actually my clutch is worn out and just started slipping (plan on fixing in the next week or so). As far as I know, it's stock.
I've been trying to do research on what clutch to get. I'm about to settle on the SR ACT street/strip/Al flywheel combo. Sound reasonable for a daily driver? I'm used to a light flywheel, but I don't want the clutch to be TOO binary.
How do you check the PPF? I'll search around for that now.....
