So you think spending a couple grand on an SS to make it a 15 second car is a sound decision...LOL
The fact is a JRSC is a viable option for the SS. It takes over 2 seconds off the 1/4 mile time. The 13.8 SS was just basic bolt ons with 555r tires. I don't really see how a road course would be a problem for a JRSC SS. The supercharger should make it quite a force out there.
If you look around you can find a used JRSC setup for around $2k, add $600 for install and you have a very good source of power. Not every auto tranny gives out, there are a bunch on PO.com that have been running for almost 2 years with a JRSC. One of them has been at 9psi for a year now.
