View Full Version : Rear quarter buckling?

10-20-2013, 12:41 PM
The car is an s13 hatch with coilovers, toe arms, 17x9.75 wheels, and rucas. That's all thats done suspension wise. The car is pretty low, the toe arms were hitting the subframe cup things the the bolts go through, but the arms bent the cups enough that it doesn't make noise any more. Yea i should get some angled arms, i know. But the thing is i thought it was the toe arms hitting the subframe which was making the noise making the noise but i've come to find out that it's actually the quarter panels flexing and buckling. I can actually see them doing it if i look in the mirrors. Has anyone else experienced this before? It does it over bumps and stuff but not all the time. It's usually small bumps that cause it. Strangely on big dips and slopes at gas stations that cause the body to flex it actually doesn't do it. I know my subframe bushings are also on the way out too, but i cant see that causing something like this. I have no idea even where to start.

Is your tire hitting your rear quarter panel?

Don't be a fucking idiot. Raise your car, and properly repair the mounting points you damaged.

You can't troubleshoot something, when you still have all sorts of things wrong.

If your tire's not hitting it, you've fucked some shit up BAD, if you have any load on the quarter panel. Or maybe, along with (and in line with) lowering your car so much you broke shit, you rolled the fenders, and now they pop.

"it's okay, now the mounting points are fatigued and going to rip off the chassis, but they're not making noise!"

I'm guessing if this is not your first 240, the others ended up parted out or totaled, but you still think you "like" or "love" these cars. Like how you'd love a paper doll... something to put new clothes on, rip up, and throw away.

not that I can see or hear, but I will pull it off and check to be sure.

mechanicalmoron, you can feel free to fuck off. I really do not need your shit. Ive seen your other posts.

Update. Tire is not hitting anything. The quarters have a somewhat aggressive pull, i'm thinking it may have kinked up the metal, for lack of better term. Like put tension on the metal and it's just buckling under stress. Do you think if I stripped the paint down and heated up the panel with a torch to maybe harden it or get it to take the shape better it would help? Or maybe weld a reinforcement on the interior side of the panel? I don't even know how to go about fixing this, that's all i can think of short of cutting it out and welding it back in without tension on it. It wouldn't bother me so much but i want to get the car painted and i feel like it can never get a smooth finish with the panel buckling all the time.

It's because of the pull. You'll need over fenders if you want a smooth finish now.

Yes it's definitely from the pull. It has tension on it now. I was thinking to either try and heat it up and hopefully it will harden or cut it and weld it back together. But i'll probably just get overs like you said

I put coils on and slightly rolled my fenders and a decent size right above the body line indented it when I turned right up a drive way. I can use a plunger and itl come back out lol but itl pop back in on a right turn up an incline (chassis flex)

Jam a basketball behind your quarter and inflate it. That will remove the crease. Otherwise your going to have to cut loose from the inner wheel well. Then pull the dent and re weld it back in a more normal position. You in no way can "harden" the sheet metal on your car. you can't heat treat or temper the entire chassis. That's ridiculous.
