Ok, Is there another size "up" in the Cooper line that's available? What is your rim width?I drive mine year round, but do drive it less in the winter and lousy weather. I drive it at the same speeds or faster than most of today's cars on the interstate and toll roads etc. It's not a Sunday driver to the ice cream parlor. I drive it the same way I drive our 97 Cobra. I also drive on road trips of a few hundred miles or more, occasionally longer.
I have a 302/306 with aluminum heads that makes about 350 hp mated to a T5 with a Versailles 9 inch with 3.50 traction lock.
Just thinking, if you run the "black" side, then, one of them foreign tire names will work? LOL!
BTW, I'm running 225x60x15 BFGs on 7" rims. Kelsey Hayes disc/drum combo. Car is lowered 1.5-2". Shelby drop, front/rear bars, 4 leaf reverse eye leafs, progressive rate front springs etc. I take no offense to your comment referencing "garbage" as suspension tuning and too many other variables can impact how one arrives at that term. Keep us posted as to your result, it's helpful.
