Freshlex adding spacer dont change your rolling diameter the tires do

 

Is it safe to use 15mm spacers in the rear?

 

Oh, so if im using the same tire on all 4's im okay with adding any king of spacer?

thank you for the insight

 

15mm spacer just "pushes" your wheel out 15mm. Don't need to buy new wheels. Kinda like adding washers...your bolt/screw sticks out further.
Should be safe for daily driving. It's debatable when tracking your car.

 

255 technically is closer to rolling diameter than 265, but im not sure if that is stretching?

 

yes, your rolling diameters will still be the same

I was really nervous about putting these on until I found this thread. Thank you. I think my car looks awesome and does yours.

 

Nicecar nice stock drop. But I becareful running 255-40 as your rear wheel be running slower than your fronts. Just a heads up 255-35 you be alot safer.

 

agreed you want keep it as close as possible the system doesn't there is any slip as in different rolling diameters. you can safely do staggered awd but you have to make sure you do the research and keep everything close within a close %

 

Thanks guys, I really appreciate the feed back. I wasn't exactly sure how to figure the %. I did measure the tires and there is a 5/8" difference in hight.

 

I JUST bought an 06' is250. I have no clue if AWD or RWD. How do you find that?
Also, I purchased a set of 09' lobster style wheels on ebay and they are all 18 x 8...not staggered.
Will I have any issue's at the dealership with them putting them on? Will it mess up my computer?

 

AWD should have the emblem on the back, get underneath and look, call Lexus and ask?

 

Yea, calling would be easy. Sucks that it's Sunday and Beverly Hills Service is closed on Sundays.

Was hoping to find info online. I don't see an AWD emblem though...so I'm assuming it's RWD.

 

Don't know why I haven't posted in this thread but here goes.
