Nice job Alex. I’ll have to go for a “boosted” ride sometime. 
The suspension up front is what kills that car’s launch. Most of the hardcore modders on SHOForum don’t want the car to go to far away from having a road/track setup.
IIRC, Mike Kopstain (also should be known to the GTP’ers here) was working on a setup for the SHO control arms to bite harder on launch and transfer the weight more effectively. Too bad he never finished it.
