Im just dreaming of a 4.0, so allow me;
For 90% track and 10% street:
As you spec it but I would black out the interior, uncluding black seat belts. Add white roll bar and black 6 points. Leave A/C in, or it will be 100% track. You can always take it out. No leather. Too hard to clean after spinning and does NOT belong in a Trackrat's Trakcar, plus you already have a blinged out baller GT2RS ;-)
For my daily driver it would be:
Delete and add nothing.
White, silver wheels, all black inside.
But please drive and beat the living daylights out of it for max depreciation, I'll take it when you sell it in any combo you order it as long as I can put the A/C back in.
Will you leave this stock? What are you doing with that old beat up blue thing?
