Hello,

This is not a lexus specific question but I figured I'd post in here anyway as I am a new lexux owner.

I've been the owner of a 2006 lexus is250 for a month now. I'm 22, been driving for 2 years and this is my second car. I'm still new to everything that has to do with cars as I havce never done anything to my first car (the first practical and affordable car). I'm just now starting to look for wheel spacers to make my wheels flush with the fender. I've read that I could have to cut the studs if they are too long when I install spacers. My car came with 17 inch wheel DAI Mephisto. In the back of the wheel there are 5 extra holes. Are these holes made for the wheel hub studs that are too long? I don't want to buy spacers and end having to return them or change them if they do not work.

Thank you, here are 2 pictures of the front and the back of one of my wheel to show what I mean.

 

No, the smaller holes are NOT to be used. Also, any wheels spacers above 5mm in thickness I don't recommend using either, unless you have ARP extended wheel studs, which I'm pretty sure you don't have.

 

These pockets in between the lug holes are to save the weight. I run Eibach hubcentric spacers on stock 18" wheels, 15mm F and 25mm R. Stock wheels have extra wide pockets. Studs and nuts fit perfectly fine, no cutting or drilling when using factory wheels. Factory studs are 26mm long, so 25mm spacer sits flush with the factory studs.




25mm spacer






You don't need to cut stock studs if they're too long, in fact for the thinner spacers 15-20mm I suggest over sizing the wheel pockets like pic below...
Any machine or wheel repair shop should be able to do this. Honestly you could even do this with Drill Press if you have access to one.




How wide spacers do you need?

 

Thank you for the clarifications, I stil don't know how widw I need/want.

 

 

find out this gap:



then buy the spacer size accordingly.
you can buy bolt on spacers (as in primavera's post) if you require 15mm or more.
the wheels you have already contain the necessary voids for them to work if the studs protrude.

 

FYI, the narrowest point of the fender-to-tire gap is not at 12 o'clock on these cars; it is nearer 10 and 2 o'clock due to how the factory fender lip is designed.

 

25mm Front and 32mm on the Rear, that's what used on my SC430. The front sits almost flush and rear, a tad in. I like it. Should work for the IS, in fact thinking getting a set for the IS as well.

 

he has aftermarket wheels which throw a variable in there without knowing what the offset on them is.
also tire sizing is another factor and how low the car is.

32mm on the back on IS might be too much poke...

 

I don't even know what the offset on a wheel is..
After a quick good search I found out the offset on my set of wheels is 45

 

7.5" wide wheels with 45mm offset, you can easily go with 15mm front and 25mm rear bolt-on spacers. I suggest getting brand name - i.e. H&R, Eibach, ST Suspensions vs el cheapo no name eBay spacers.
