The front set up will be the problem the rear should work for now.

 

I'm running a 20x9+12 with no pull just shaved and rolled and I only rub slightly while turning but that is because I'm tucking 1/3 of my front tire all that is needed is to shave the fender and maybe grind some of the front bumper bracket down and you ll be fine.

 

for the better i hope!!

 

if i do lower it i will get the rca blocks for the front. to me it seems the gs450h sits lower than the other gs's. maybe it is because of the weight of the batteries in the rear?? i dunno...

 

20x9 +36 245x20x35
20x10.5 +42 275x20x30

Rubbing front and rear.

After shaving all four fenders corner no Rubbing issues. =)

 

wow rubbing with those offsets? how low are you?

 

to be honest, i don't know what some other people say, but what lexus gs3 stated, even at stock height, if you hit bad enough of a dip, you will rub. when you lower the car, you shorten the suspension travel that's all, meaning it rubs more. at stock height, if you hit a dip and suspension compresses, it's pretty much doing similar action as "lowering" the car. so if a setup rubs when lowered, having it at stock height won't make it not rub, just less.
