RTThe RT option opens the center of the wheel allowing easier access to the lugs and removing approximately 1 lb per wheel. There is no provision for a center cap with the RT option, and the RT option is not compatible with the Centerlock option.
$0 No Cost Option per wheel
Center LockThe Center Lock option is required when using a uni-lug hub. Examples are the factory Porsche center lock, and many other racing applications. This option cannot be combined with the RT option. $0 No Cost Option per wheel
Knurled Bead SeatThe Knurled Bead Seat option increases friction in the contact areas where the wheel meets the tire, and limits tire slippage under heavy braking and acceleration. This option is highly recommended for track use.
Included at no charge
UltraliteThe Ultralite option is an additional machining process that removes material from low-stress areas on the extremities of the wheel. This option allows us to produce a more deep/narrow spoke and ultimately a stronger wheel. It removes approximately .75 lbs per wheel and has a dynamic effect on rotating mass. This option is available on all-wheel models.
$250 per wheel
ProThe Pro option is an additional machining process that removes material from low-stress areas of the wheel, specifically, it I-Beams the spokes. This option removes approximately 1 lb per wheel and is only available on the F5 and F10. This option can be combined with the Ultralite option.
