Hi guys, im thinking of getting these wheels for the F but dont know what offset to go with, without rolling fender. These wheels are available in 20" only with width from 8.5-12 i believe. Im lowered on KWV3. Ravspec has a set in 20X9.5/10.5 listed to fit the IS250/GS350/LS430 but they said the fitment is too aggressive due to offset. Im hoping some one here running TE37 or anyone that has offset knowledge for our car can help me figure out. Thanks in advance guys

I'm not a wheel expert, but you may want to get your speedometer calibrated if you're going with bigger wheels.

Speedometer won't be affected if you choose the correct size tires for those 20". Around 26" dia and you are good.

Back on the offsets topic, 9.5 +23 or greater is ideal for the front. 10.5 +35 or greater is ideal for the rear. It's very hard to find 10.5 +35 now a day, mostly custom stuffs

Thanks MK4Sup_isF, i thought so too regarding wheel diameter and will follow your guideline for offset. Merry Christmas
