275's on a dart sport

No 13.25 is inner to outer. I edited the post to clarify this.
The folded lip would technically be subtracted from the gross, but my 50 series sidewall bulges don't get up that high. And while the 325 treads are inside the wells, actually, the sidewall bulges are not.IIRC the 325s are 13.25wide on the largest part of the bulge, and the tubs are also 13.25. So, having clearanced the inside to 3/8 inch,the sidewalls are that same 3/8 inch outside the body. But those bulges were initially 5 inches below the lips so it was not an issue. Since the sidewall is 6.4 inches high, the tread was up inside the tub by 1.4 inches. It has since been lowered quite a bit, cuz I don't run those anymore. On the street those 325s had no more take-off power than the 295s, and the 295BFGs cost a fraction of 325DRs, so I am "saving them" for if I ever want to track it again.
At one time I was running the K at 5.5inches off the deck, and a 1/2 inch rake on the rockers. But that did not sit well with city driving, even with 1.03s and the 1.125 bar and HD shocks. So I jacked it up incrementally until I stopped whacking the skid plate I fabricated to protect my oilpan. IIRC it ended up at a tic under 6, and the rockers are now level.And I can now get air over speed bumps.heehee. Yeah, I'm a Dukes of Hazzard kindof guy.
