Going LeMons racing in a 6GC! Options

[slavie]

Hey ya'all!

A series of questionable decisions have led me to getting accepted to my first LeMons race coming up at Thompson, CT in August. Not much time left, lots to do.
If anybody is seriously interested, I'm still looking for the 4th driver. Hit me up.

The car came from 6gc community - I picked up Rymaster's 96 GT (his FS thread)
Car has an issue with the gearbox - makes really funny noises. I suspect something off with the diff. Drivetrain is already out of the car, gearbox separated, waiting for me to get wrenching on.

Cage installation is lined up for a week from now.
Need to completely redo the brakes - rebuild rears, replace fronts with dual-piston calipers, new rotors and pads.
Replace wheel bearings as a precaution.
Figure out what tires I'll use.
Finally, all the safety bs - kill switch is a must, and I'd like to plumb fire extinguisher and cool suit in if funds and time allows. If not, hand held extinguisher and sweaty balls will have to do.
Tons more crap I'm sure will come up.

Interior is getting completely gutted, so feel free to inquire if you need parts (I'll be posting a FS thread, will put the link in here). Any money I make back on selling parts I can use towards "performance mods", and I'm looking to get some decent lowering springs (no thanks to noname crap). If you have a set of such springs collecting dust - talk to me.

If you've done LeMons before and have suggestions, fire away.
