Marty,
I'm not sure on VTA fronts vs. the D compound X patterns...Maybe Kevin has something to add.

There will be a concours...prepare your dioramas now!!

Some things to remember for the USGT class

Wings you may use an ABS plastic molded wing like Tamiya and Hpi sell, or you may use the lexan wing that comes on the car but wing height is restricted to 10mm height for LEXAN WINGS ONLY. The molded wings are not restricted.

ESC You may use any of the USVTA listed escs or an esc in ROAR approved spec mode

Motor Any ROAR 21.5 motor

Bodies No current ROAR T2 sedan bodies, and for that matter, no Stratuses, Alfas, Accords, etc., that have fallen off the list. GT, DTM, LeMans 2 door type bodies please--scale look being most important. 4 doors are ok too if they are not "race" sedan bodies. No trucks!
