The owners dad is also a porsche mechanic and built the custom exhaust. The fuel pump was relocated to the front of that car due to temp. issues, also that is what that little red switch is for on the right of the steering wheel. I want to tighten up the suspension (new bushings, adjustable shocks and springs and anti-roll bars). I think it has minilites on it (6-spoke wheels that look very similiar) and I am not sure what tire combo (something else I want to address, what is the max tire size that I can fit on there w/o modifying the body fenders (something I am considering now). The engine is as far as I want to take it for now, focusing on the stuff that will really make it a momentum car (autocross is my goal). Engine is like polished aluminum, it looks beautiful. The owner told me if I want to do any work on it he is glad to set a date and go work on it over a couple beers (porsche mechanic of 15 years).

Body mods (have a rear lip spoiler but I want a race airdam for the front
SS brake lines and some cross-drilled rotors and new pads
New Tires/Wheels (maybe on the wheels)
New Shocks/Springs/Struts/anti-roll bars/ball joints (koni for the shocks)
Coilovers available?
Fiberglass fenders
Chassis Stiffeners (Light Roll cage/bar to put in the cabin and strust to put on the shock mounts)
Anyway to easily lighten it? (fiberglass or CF hood)


I am just curious were the hell people get parts for these things, I can't find them anywere. The online store here is out of commision for now.
