I noticed nobody brought up aftermarket wheels such as slotted mags, Cragars, Eagle Alloys, and such. They don't touch the hub center at all! So how do you explain that. I can see what you say about the lugs carrying the load and the flex and all that, but fro cripes sake man, it's only 1/2 an inch not 4 inches! A 1/2 of an inch isn't squat. Matter of fact, most your aftermarket wheels that require shank type lug nuts have at least a 1/2 thicker mounting face (esenitally like adding a 1/2 spacer in the same respect) so how is that any different?? Look at E-t and Crager wheels! They dont ride on the hub and the only contact between the lug and wheel is a 1/4 thinck washer! And... how much weight you gonna carry on those hubs??? The rear weight of that car alone is barely enought to even worry about unless you plan on towing a trailer or hauling barkdust with your II. Gimmie a break, you guys are killing me with this stuff. We turned circles with 15" wheels and 245/75/15 tires on our race cars week after week and i NEVER had any problems, nor did anyone else. Wheels fallling off... bah... a bunch of crap... guy probably didn't torque 'em right or forgot 1/2 the lug nuts. Now anyone with ANY common sence that NEEDED to run a spacer on his/her slicks, I'd say buy you some new wheels. Because in drag racing you're 'shocking' the whole drivetrain at every takeoff from the tree. Runnig spacers with slicks is pretty much a no-no. Too much instant stress to the rear wheels on launches could make them a weak point. Bottom line is, if you NEED to run spacers, and you're really that paranoid about them, get a slip-on set specifically machined for your bolt pattern, use ARP wheel studs and nuts and check the torque on them often and I doubt you'll EVER have any problems with running spacers. Oh- BTW, IIRC the wheel spacers I was running were, I think,Competition Engineering units that were purchased at my local speed shop, circa '95-'96. Can't remember for sure, been a while since I ran circle track.
