Sounds like you've already disregarded a lot of good options/already on very decent rubber. May I be controversial and suggest maybe driving style needs adapting? My suggestion if you're set on tyres is to go wider. My kit has 232lbft (200 from 1750rpm) and with my lowly Toyo Proxes, will spin the wheels in 1st for sure, but in the corners and 2nd its all very controllable to allow me to drive briskly (its a public highway after all ;) lol) Comes down to how you use the loud pedal, its not a switch is it?
