Okay, I'm back to bother everyone again....
I was under the impression that five-lug axles (at a minimum) were mandatory across the board in LSR. But as I was checking out Speedweek '03 and '04 photos of my Pinto brethren on the SCTA website (car numbers 1972 and 7001, I think), I noticed that both cars had five lugs in the back but the stock four-lug pattern up front. I assumed that they didn't just sneak past tech, so I went back to the rulebook. The relevant part of the wheel section reads as follows:
"Vehicles with tires having a diameter of 29" or greater, or with wheels over 17" in diameter must use a wheel manufactured for racing or reinforced as below. Wheels must be attached with at least 5 studs with a minimum diameter of 1/2" and 1" lug nuts."
So have I been mistakenly applying the 5-stud rule across the board, when it actually just applies to 29" or larger tires and/or 18" or larger wheels? And can I assume that if I'm running 15" wheels and 25" or 26" tires, that I can theoretically use four-lug axles up front? (I'm already swapping to 5-lug Granada axles in the rear.)
Thanks--
