Just got a SC300 and looking to put air supension on it with wheels(see specs below) and fenders rolled and pulled. Looking to get that flush look.
front- 20 X 9 +15
rear- 20 X 11 +15
1) My question is what size tires should I run to clear fenders?
2) Also, what others parts do you replace or upgrade when you are on bags since the car is on its nuts when parked?
3) Thinking about UAS on kyb gr2's or k-sport air ride? Or would you recommend something else?

I can only help with question #1. I'd run a 225/35/20 (smallest 20" tire they make) on the front and a 255/35/20 on the rear.
Like Kohinoor said the SC section or vipstylecars.com is your best bet for the rest.

You ll likely be close to an inch over spec with a 225/35-20 a 225/30 would be closer to factory overall diameter(atleast on my car) but you will definitely need a stretch. Best thing to do is install suspension first then calculate what you need for offsets followed with a nicely stretched, small tire. Or bite of someone elses fitment and stance if you can get their honest specs. Good luck!
