Final update related to the install. I finished the install last night and autocrossed today.
I used my 15" wheels and Radial T/A's knowing they would be terrible, getting any sort of traction was a joke. I need to upgrade to real tires soon. On my first run I got red flagged for part of my exhaust falling off, on the second run one of my heater hoses developed a tear. I fixed the hose between the morning and afternoon runs. The good news is I wasnt the slowest person. I ran a 56.3 on my final run, improving 3 seconds over my next fastest run. FTD was 44.3 by a Miata. An average fast car on good tires ran about a 48. I'm confident with good tires and an LSD rearend I can almost be competitive, albeit still on the slower side because of the long wheelbase and weight.
