First off, welcome to the Isf & this forum.

In answer to your questions on coilovers for the Isf, you do not want to use Is350 coilovers on the Isf under any circumstances, even if they have heavier rate springs installed.

Judging from your location, I'd guess it's likely you are fortunate enough to be able drive at high speeds on smooth, lightly trafficked roadways. Accordingly, I'd get rid of the Hks you currently have and look into one of the options available from Club Lexus vendors such as the Ohlins from Fig's or the Penske's from RR Racing with in 18 kg/mm front and 16 kg/mm rear spring rates. Both of these vendors are extremely helpful with determining what will work best for you and maximizing your driving enjoyment.

I think you may have a different issue. Perhaps the wheels without spacers are too inset and thus rub on the interior wheel well. Or the coilovers are old or incorrect and for IS350..? I am lower than you with HKS and don’t rub. Same tire size too
