Actully I remember him solving the crank walk issue on his, since that was one of the issues he dealt with and is common for those cars. I forget all the stuff, but it didn't pan out to be a realible race car/daily driver. His Camaro proved to be much better in this catagory, and much better faster too. I think he got a better car in the end, but thats my opinion. I would of started with an LSX car to begin with because of the cash flow he had availible.
I guess if you want an all out race car, a DSM could be an option (just like any all out race car, you will be wrenching on them). But honestly why would a choose that when there are plenty better options in the RWD V8 catagory. Thats me though.
He had fun with his DSM and he had the best of the best parts availible at the time. I seriously doubt he'd ever do another one though. To each there own.
