25mm H&R spacers. It is actually nicely flushed against the fender. It is just the angle of the picture that was taken which doesn't fully show how flush the wheels/tires are sitting at. Mind you, that i did mention i am running 17's which is 225/45/17, 17x8. 18's rear are 255/40/18, 18x8.5. The pic was only giving a reference to OP that roughly 20mm - 25mm will do it. I will take better pics when weather clears up to show a better angle . But as you can see, i marked an arrow pointing at where the tire is sitting, which is pretty flushed against the fender. I am not going for any "hella" flush or crazy offsets as it is just a normal winter setup.




EDIT:
Maybe this picture will give you a better idea About 2.5" drop in the rear by the way.

 

Hey guys so what size Wheel Spacers Are needed to make the Factory 18's FLUSH on a lowered 08' IS250?

Do I need 10mm Front, 15mm Rears or something else?

A link to the spacers would be great! Thanks guys!

 

read page one 15mm front and 20mm rear. Check ebay for the V2 direct bolt ons.

 

Sorry about that, I read the thread multiple times actually but couldn't come to the conclusion as to which spacers were for the 18's, as the posts are kinda confusing...

 

20mm front, 25 rear, ichiba v2

 

Mister T did a nice photoshoot of before/after with oem 18s

I read a thread today where spacers are bad.

 

Your welcome!!! After I saw these pics, I was going to get spacers for sure, which is why I had this thread on my favourites.

However, after I read this I decided against it!!! Anyone putting in spacers should read this first:

That looks like it could be from being over-torqued. With the V1 spacers, that would be much less likely of NOT happening. With the V2 spacers, the spacer is taking all the weight of the wheel whereas with V1, the spacer is just compressed between the wheel and the rotor and the weight rests on the extended lugs, as if it were stock.

 

Not sure if anyone's still posting to this but I've installed 15mm front/ 25mm rear on my OEM 18s and ide say they sit flush.

 

Oh man that looks awesome can I please see some side shots?

 

Hmmmmmm. I kinda wouldn't mind spacers either. Lol.

 

If that was true then all German cars would have paint peeling off on those body panels. Pretty much all of their cars have flush or nearly flush look straight from the factory.
I have yet to see Mercedes, Audi, Porsche with scratched paint around the wheel wells and fenders.
If somebody takes nice Lexus off-roading into the mud and sand the chances are the car is not the only problem they have.

 

If you want a flush look, why not buy wheels with aggressive offsets. Leave oem 100% oem otherwise go non-oem.

 

Wheels admittedly look better when they don't appear sunken in. I have isp modes and don't hate the look of them. So spacers would accomplish the goal of decreasing that unwanted look. So I'm sure there are people who also have this line if thinking. My setup doesn't overly offend me but also think that ot would look better if they sat closer to the fender. With that being said ; I plan in ordering wheels from evasive motorsports in the next 4 months(ish) so spacers would not be the most appropriate option for me nor really the most cost effective since they're not the cheapest things out there. Maybe if I had them when I first bought the car three years ago. But to each their own honestly. Wow thats long.....
