I did a search already with no results. I have a chance to get some 18x7.5 LE37 for a good price. But would the offset of 40 work all the way around? Please help me out.

 

i know this doesn't help, but i must ask....

why are you going with such a small width?

the small width combined with the high offset will result in a weird stance.

just my 2 YEN

 

Well the rims are being sold locally. It's on a IS300 right now. I can always get wider in the back later but I need to know will it fit for now. Thanks in advance.

 

assuming you currently have the 18x8 performance wheels:
Your new wheel will have the following chracteristics:
The clearance from stut housing to the inside of the wheel will be 4mm LESS
The outside edge of the wheel will RETRACT in towards the body by 16mm

For $40 a pair, you can get these from www.summitracing.com :
TRD-7069, they are a 1" spacer. the spacer bolts to your hubs, and the wheels bolt to the spacer. 1"= ~25 millimeters, for an effective +15 offset, or
Your new wheel will have the following chracteristics:
The clearance from stut housing to the inside of the wheel will be 21mm MORE
The outside edge of the wheel will EXTEND an extra 9mm

SUMMARY: It will be fine with a spacer, but not without.

 

oh yeah, I have these spacers for my drag wheels.

 

So I guess in the front it would clear. Then I would probably just need spacers for the rear? .....Seems like to much trouble do you guys think it's worth it?
