13.3
- Any tires that fit the OEM wheels and fenders are OK.

Bridgestone RE-71R 285/35r19 square on OEM Rays 19x9 front 19x10 rear rims is your best bet here. You can get a set of those for $600 on the forum if you're patient.

13.5
- Shock absorbers.... No idea... Help?

Basically Koni Yellows are your most reasonable choice here. Won't break the bank completely, adjustable, quality shocks. Can't change the springs though.

13.7
- I can use 1 aftermarket bar. Any bushing material is permitted.

Hotchkis front sway bar, OEM rear bar. Again something you can usually pick up cheap on the forum.

And yes you can use a cat-back exhaust. Not much else for power mods or that'll bump you up a class. STR sucks for the Z because you're limited to 255 tire size which is nothing for such a heavy car.

Won't the change in width from Base to Sport wheels knock me out of BS?
