My other option is to go with larger and stickier tires. Like 295 tires (rear only) like the Hankook Z214 or Kumho 710) and use up as many point that I can and stay in TTB...

BTW: If I re-install my stock springs, I can run both classes by just changing wheels/tire combos....I have a set of 4x 17x10 and 4x 17x9.5 wheels...This is a very good option so that I can run in the class that benefits me the most on a given weekend.

TIRES:
1) DOT-approved R-compound tires with a UTQG treadwear rating of 40 or less (ex. BFG R1, Hankook Z214,
Hoosier R6 & A6, Kumho V710, etc.—note: G.A. Cup Hoosiers OK) +10
2) DOT-approved R-compound tires with a UTQG treadwear rating of 50 to 130 (ex. Kumho V700,
Michelin Pilot Sport Cup, Nitto NT01, Pirelli PZero Corsa, Toyo R888, Yokahama A048, etc.—
note: see exception below in 3)) +7
3) Toyo RA-1 and Nitto NT555RII +5
4) Non-DOT-approved racing slicks +30 (of an origin—re-caps and re-treads are not permitted)
5) The following tire sizes will be used as the base tire size for each Base Class for all vehicles regardless of their OEM tire
size(s). All vehicles in a given base class may use this tire size (or smaller) without a points assessment:
TTA: 295 mm, TTB: 265mm, TTC: 255mm, TTD: 245mm, TTE: 235mm, TTF: 215mm, TTG: 195mm, TTH: 175mm
Increased tire width beyond that listed above (using the largest increase of front or rear if using split sizes) will be
assessed as follows:
Equal to or greater than: 10mm +1, 20mm +4, 30mm +7, 40mm +10, 50mm +13, 60mm +16, 70mm +19,
80mm +22, 90mm +25, 100mm +28, 110mm +31, 120mm +34, etc.
