My buddy has a stock 2002 IS300 sportcross and was thinking that a 18x9 +35 rim would make it flush, I tried searching but found little info on the subject. He will be getting coils soon so height wouldn't be much of a problem.

Any help would be nice

Thanks,
Ravi

Will need to modify fenders. Front should be solid (with some camber)....rears should be closer to like a 9.5"+35 for flushness with at least a 2" drop all around.

+36 is going to have you roll the fender a lot. Just keep that in mind. My setup is
18x9.5 Front +12
18x10.5 Rear +15

You may only need to roll the fenders as long as you run a stretched tire like a 215/40 front and 225/40 rear.

there needs to be more information than just saying that he wants 18x9 +35. What kind of tire spec is he going to be running on? Does he like meaty tires or stretch tires? Does he mind rolling and pulling the fenders? Does he want spacers or no spacers? All these questions will need to be considered, because if he is going with 18x9 all around. His fronts will poke and his rears will be tucked.

Stretch tires: Staggered setup will make it look flush in the front and rear. For instance, 18x9+35fr 18x10+35rr will be a good combo for a flush setup all around. He will need to roll his front fender tabs and roll/pull his rear a little to accomodate stretch tires.

Meaty tires: He shouldnt do 18x9 in the front, because he will wrinkle his front fenders. Unless he rolls/pulls his fenders.

This is my old setup on AirSus
just a fender roll in the rear and you wont rub on 18x9 +35 tires: 235/35. I had fr18x8 +35 tires: 215/35
I dont know what height I was at. Camber and toe were still within stock specs when I had my alignment done at this height.
Rear only

Not to thread jack but I'm the process of getting new rims for my ride. When I purchased the vehicle the previous had put rims with the incorrect offset meaning there had to be a spacer put on to clear the caliper. I'm looking at a set of 17x7.5 or maybe 17x8 but I'm unsure what offset is safe, because I don't want to use the wheel spacers.

^^^^do you have pictures of your wheels and calipers? There could be a reason why he used spacers, and offset isnt the main issue, but it is part of it.

Pics will help a bunch

Will do once I get home from work. When I did a brake job I removed the spacers and once I put he rim back on the car, the caliper was pressed up against the rim. This prevented the car from moving. I had to put the spacers back on so I could drive my car. The main reason why I want to get rid of the spacer is for tire service. Tire shops won't touch your vehicle if it spacers.

Ok I just threw a number that I thought might be decent after some research, I know he wants a meaty set-up because he wants to be boosted later on. Also, it looks like its better to run a staggered set-up. I know he wants to roll his fenders but I think he wants to later on, and I rather him not run spacers if need be.

Thanks for all the help,
Ravi

here is what happen when i didnt have the spacer on the hub





if you look at the spoke you can see where it was bent from sitting on the caliper while i was attempting to move my car. so whatever offset these rims are, its just to high for the vehicle to require a spacer. i just dont know the range i can go with on this vehicle. my current rims are 17x7 i believe, i would like to stick with 17's because my tires are fairly new

Thats a bummer
This could be many reasons for the wheel to hit the calipers. My first theory is that the wheels were meant for a different car with smaller calipers. If that is the case, then it isnt the offset that is causing the problem, but more of the disk factor. Its the center of the inside part of the wheel. The flat area where it fits flush on the rotor and the lugnuts attach the wheel to the car. Spacers are needed to clear our calipers. There is a way to figure out what offset the wheels are and what disk depth you have to figure out what is causing the rub. And I can not answer that for you

2nd theory, go buy new wheels that will fit your car.

The stock wheels are 17x7, (this is by memory), +55 offset all around on sedans.

I agree with the second theory! I just need to know what range to look for, before I buy the rims of choice ill email the seller to find out if spacers are required. Another reason why I need rims is because 3 out the 4 rims are bent. Not sure how it happen but I need to replace them. Thank you for your support if anything else ill send you a PM when I find something I like. I'm trying to get away from spacers, I hope I don't have this same problem when I get a GS
