A member from Chevelles.com asked sc&c and got this response:
[quote]"The `69 gets it`s stance from a combination of our Street Comp Stage 2-Plus package and Hotchkis springs. In that pic it still has a stock swaybar in front and no rear bar. I`m told he was doing close to 90mph in that pic. It`s got 245-45-17 in the front and 315-35-17 in the rear. AFAIK all he did was measure the backspacing (if memory serves he used 5" BS) very carefully and roll the rear fender lip. He`s since upgraded the swaybars and shocks etc. If you have any other questions I`ll do my best to answer em."[/qoute]
No, there is no way we were doing 90 in that picture. My Corvette is about equal to his Chevelle and I was getting 80 in the back straight. I'm the one in the passenger seat and the driver is one of my good friends. I'll tell him about this thread so you will get your answers.
Featured it? No, I don't think so. I would have known about that. It might have gotten in there for being at one of these autocrosses, but not featured.
17x11 rear 6.75" backspacing
17x9.5 front 5.5" backspacing
275-40-17 front tires
315-35-17 rear tires
Stock rear wheel-wells with the fender rolled just a little.
To fit the 275 in the front you have to have tubular upper control arms. He has the SC&C upper control arms and is waiting for their lower control arms to come out.
He does have the SC&C Street Comp Stage 2-Plus package, Hotchkis springs, KYB gas-a-just, but still has stock front sway bar and no rear swaybar. No further suspension mods have been done since that picture.
He said that he got his backspacing info from Chevelles.com
He said he'd stop by here later so if you have any more questions about it, please, go ahead and ask.
