My Wayne Due C5 frame is cracked

[streetk14]

I just noticed this today, and I'm glad I did.

I was quite happy to get the car back on the road (after having it down for a supercharger project), and took it for a little drive this weekend. I noticed the frontend had a little shimmy and didn't quite feel "right".

When I got home, I glanced at the right front tire and noticed that it appeared to have a bunch of negitive camber. So, I opened the hood to take a look at the upper control arm bolts. I was surprised to find the whole upper control arm mount nearly broken off the frame rail. I'm not sure how or why this happened. I have not been doing any hard cornering in the car lately, and have not hit anything.

I just upped the power of my motor a good amount, and it is putting down 505 hp and 470 tq to the rear wheels on the dyno. The torque curve is impressive and I'm sure it's putting some strain on the chassis, but I wouldn't think it would cause the frame to break like this. I have been doing a lot of full-throttle blasts lately, but don't know if that has any relation to my problem. The only other thing I can think of is that maybe there was a bad weld that slowly got bigger until it finally let go.

Most likely, I'm going to get a new, bare subframe from Art Morrison (AME) to replace this one. Most of my C5 parts will swap over, so the cost shouldn't be too bad. I'd like to talk to Wayne about having it repaired, but I'm not sure if he can be reached these days. What do you guys think?
