SCCA has already announced that 5-pt belts will NOT pass tech efective Feb 05.
So why choose an 'already obsolete' system?
If you "call Curt" you will learn a lot, but he is very honorable and respectful to his VCA VENDORS who helped him develop this product. Cusrt will only sell at MSRP/Racer prices. Archer or PartsRack Please? You will save a lot.
P.S. If you drive an open-wheel lay-back chassis, indeed select Sabelt or Shroth or Willans. Especially if they are sponsored and you dont pay for them! But in a Viper? TEAMTECH! They have saved lives: Ask Tommy Archer
