VW - The car comes with 15/18T pinion gears. After testing newer gears that are taller than the stock gears, I'm pretty sure you want to gear down instead of up with a high-revving on-road motor, or at least run with the stock gears. You don't HAVE to keep a 3T split between first and second gears. You can cheat 1T on the clutch and get away with it.
Utah, I'm working on a set-up sheet for the car so it will be easier to share this information. drop the upper links on the shock towers front and rear, and with the TRW105 shocks I'm running the optional silver springs in the front and black in the rear, with 1200 shock oil in the front and 1000 in the rear. The diffs are 30K front and 3k rear. I also run anti-roll bars but the thickness depends on the bite.
Vision - yes, a brushless version will also be available. I'll post up some rear shots a little later.
66 - I imagine it would work, but I've never tried it so I can't say for sure.
