Need - Get as much mechanical grip as possible F&R, using better a better chassis, suspension and tires.
Restriction - Physical size constraints, 285s on 20s in the front are already very close to the suspension and fender. (ZL1 1LE has narrower springs, wider finders & shorter rims.)

I can tell going from 15 LE to 18 SS 1 LE.. The SS 1LE at Autoclub Speedway Roval after the tires were heated it produced more understeer than desired with mode set on full track. I dont know if the 285s upfront causing it with ELSD keeping my rear in check but the 15 1LE was more tolarable in understeer on the square setup.
Im thinking to promote less understeer on the 18 SS 1LE is to do more late braking. Thus having better weight on the front until mid turn and gas a bit harder before understeer is pushing me out to the corner exit. In essence having the rear turn with throttle steering working in my favor.
If that does not work then change to a square setup with wheel spacers up front running 305s on track wheels. Also adding a front splitter extension and dive planes for more downforce...
Too me it seems the rear is planted and not the issue.. the 285s/305s non square is.. but if that changes during my experiment add the wicker bill. I will accept more drag on straight line speed.
Note: the 285s on 11s is a bit of a sidewall issue with me on exposure of the edge of the rim and streching for most tires. I can add rock guards to deflect most of rocks hitting the side of my car with the 305 square setup with wheel spacers added for clearance of front struts. Then agian leave everything as is and adjust my driving knowing the limits the car has or likes.
