If I were to get aftermarket 19"x8.5" rims, what offset should I be looking at? 43?

Would it be different offset for the rear?

 

19x8.5 should work just fine in the front with a +43. you can get a bit more agressive if you want. another member on the board runs a 10.5 with a +43 in the rear using a 275/30 rear tire. from what i have gathered most conservative offset wheels from the GS and Supras will work on the 2g IS.

 

I have a AWD, I'm not looking to go for a staggered look. Although it could be done, there is no point. Will 8.5 in the rear with 43 offset work?

 

AWD should same offset and wide of the wheel all around
for the RWD
should be able to fit +25~+30 offset
with stock 1/4 penel
but if you want more lip you will need some fender roll or over fender/ custom wide body to make it fit
i think RWD should be able to fit 9 (F)/ 10 (R) with right offset

 

unless you're going with a narrow wheel, i dont think 25-30 will work. the 350z,G35, SC430 take 25-30 offsets and the GS and supra wont. with AWD 19x8.5" and +43 will work fine. post some pics up when you get the wheels put on.

 

I agree. The IS350 at the Volk booth in SEMA had 20x9.5 +37 offset. I'm thinking that for the rear, you need at least +36 on a 9.5" wide wheel.

 

wow, +37 and 9.5... these cars can take some agressive fitments.

 

well.... i dont plan to put wheels on my car
since my S14 already got me into alot of trouble
the offset i just kind think from the S14
cuz normally on the wheel site , they always want ppl to put on big offset wheels
like for my S14 work wheel said +35/+40/+37
but i put on 17x8 +9 (F) 17x9 +7 (R)

 

here is how i have done it with my S14




i know its IS forums , so now im going to put on my IS

 

I have 19x8.5 +38 offset in the front on my IS350 and the tire rubs sometimes when I am turning. My tires are 245/35.

 

4WD doesnt have to be the same width all around, you just have to utilize a package with the proper specifications. We recently did a AWD car with 22x9 and 22x10.5 with no issues.

Also offset doesnt affect AWD, rolling diameter does.

If you need help with wheels, just let us know!

What do you have in the rear?

 

that's what i thought too, that's how they do staggered on cars like s4 or so

i just don't understand why in one of the review with lexus designers, they asked if they can put the 18" staggered on the awd and they said explicitly *no*. i am still wondering, coz' when i get my ls600h (if that happens), i want to put on staggered...

 

for Awd its better if it all the same size all the around , cuz the engine is giving the power to all 4 of the wheels
of cuz you can do the RWD set up, but the its just wont run as smooth as RWD / rwd set up

you can play the tick on the tire
but it just not going to work that well, like putting S14 wheels offset on a Skyline GTR

 

I have 275/35 +45 offset in the rear. The back fits perfectly, no rubbing.
