I saw his pics bot I needed a little more detail Was hoping someone might have some.. I didnt look under the backside of poison dart on the tour..Wish I had now.. Also it has been reported to me that the Heidts IRS may fail at certain power levels. Some that have done these believe the corvette irs is a better choice.
I think I might have a few more of the Dart, and of Delaney's Cuda. The Cuda has ALOT more reinforcing than the Dart does. I don't think the Dart is actually running yet, but I know Matt has literally beat the life out of that Cuda trying to break it, and nothing happened..
I'll try to find those pics tonight when I get home.
Here's the perfect shot. The rear of the Dart before it was painted. The other pic is from Matts car - notice instead of a straight crossmember for hte forward struts, he used an X-brace across the frame connectors.
If it was me, I'd probably do a straight crossbar. I think it'd be plenty strong enough. Although I can't argue with Matt's method - he goes out of his way to make car bodies completely rigid before they get painted - unbelievable amounts of hidden metal work.
