Default Help: Broke ANOTHER rear spring

So, I broke the stock rear spring on my '01 Coupe. The car's got just over 32k miles on it, but I figured, what the heck, it could happen... right?

Well, within 24 hours, and less than 50 miles later, the new rear spring broke in the exact same spot. I'm not hitting holes, or driving aggressively. Nothing looks to be out of whack, other than the spring just broke, again.

My only thoughts are that my dumped exhaust is superheating the suspension and causing it to crack, but it's only doing it on the passenger side. Anyone else heard of this, or got anything I can check?

I believe you answered your own question.

Where is the dump/cutouts?

A member of my old car club here in Houston owned a World Challenge team for a while. They originally had the exhaust dumping in front of the rear axle. They had the same problem with the rear springs failing. That is the source of your problem.

Your springs are made out of fiberglass and the heat is causing them to get brittle and break.

Solution change exhaust or buy coil-overs.

Car's basically just running an open Corsa X-pipe.

I had it dumped further back before but all the added weight caused one of the exhaust hanger springs to break.

So I inspected the original stock spring and it showed signs of cracking on the driver side as well. It looks like my exhaust is angled a tad more to the passenger side, which is just enough that it heats the hanger/bushing on the driver side, but lands directly on the spring on the passenger side.

So, anyone got a rear spring for sale?
