You have a couple of choices: 225/70R15 (27.40 OD) or 255/60R15 (27.10 OD). BF Goodrich TA

The Radial T/A molds an all-season tread compound into a symmetric independent block pattern featuring unique tread block phasing and variable groove angle geometry to provide low noise, predictable performance and year-round traction. The tire's internal structure includes twin steel belts (50-series sizes add BFGoodrich's ETEC [Equal TEnsion Containment] System of spirally wound nylon) that stabilize the tread. BFGoodrich's g-Wedge technology makes this the best performing Radial T/A ever by featuring the high modulus sidewall stabilizers found in many of BFGoodrich's higher performance radials (g-Wedge sidewall stabilizers increase torsional rigidity to enhance lateral stability and steering response, while delivering a smooth, comfortable ride).

The Radial T/A is BFGoodrich's Performance All-Season tire developed for the drivers of muscle cars, kit cars, street rods and light trucks looking for wide, low profile, white-lettered performance tires. Today's Radial T/A tires are designed to combine classic looks and size range with modern manufacturing methods and year-round traction, even in light snow.

The real problem is that the manufacturers don't really make much anymore for 15". That's the reason I went to 17" on the front and 18" on the rear. If you change the wheel size you will have a great selection.

in the stock class that I run in I can only run a size available to that model/year specific car at the time. So I'm stuck with 15" Thus my problem

I used a stock 1 1/8" front bar and 9/16" rear bar and got pretty close to neutral steering w/ just a tad bit of oversteer when I used to autocross.

I'm allowed to upgrade 1 sway bar dso I thought if I went to a larger rear sway bar that might help plant my front a little better

Both bars that I used were part of the Gymkhana pkg.  Putting a rear bar on or increasing the rear bar diameter will reduce understeer/increase oversteer.

Check into the new BFG G Force TA. It is designed for performance cars. Not sure if it will solve your issues but may be the right answer. They were just released late this spring and may be hard to find. If you decide to use them and cant find any in the size you need let me know as I work for a tire dealer that handles BFG.
Warning though, as previously stated, 15" tires are getting harder to find! The manufacturers dont care about our muscle cars. They are interested in sales and the 17'sand 18's have taken over the manufacturing lines.
