I'm looking into getting a set of seats for my EK but I need to make sure they will be legal for SFWD/Turbo 4. I am a fan of the VIS CF racing seats but from what I heard they are not 'approved' but can be used by encorperating a back brace to the roll bar behind the seats. I will be driving this car from time to time on the street so I would prefer to get these over the regular kirkey's... I've sat in the VIS ones and they are actually comfortable.

So as the rules state:

"The driver’s seat of any car in competition must be constructed, braced, mounted, and upholstered to provide full back and shoulder support. The driver’s seat must be supported on the bottom and back by the frame or crossmember. Except as noted in SFI Specifications, seats must be bolted with four bolts (and nuts and washers) on the bottom and one bolt in the rear into crossbar; all bolts must go into frame or crossbraces. Ball-lock pins for seat attachment prohibited in all classes.
All seats must be upholstered, or as noted under Class or SFI Requirements.
Properly braced, framed, supported, and constructed seats of aluminum, fiberglass, carbon fiber, or double-layer poly (accessory seats) permitted. Single-layer fiberglass seats must have steel tubeframework, 1/2-inch minimum O.D., for support. Aftermarket aluminum seats must have reinforced head rest. Magnesium seats prohibited."

Anybody have any more info reguarding this or other options as far as seats go or a contact e-mail I can reach one of the tech's at?
