2011 Lexus is350 AWD stock.
I have had quite a bad experience getting squared wheels to fit.
They all hit the front brake caliper.
1 set from Fitment Industries and 2 sets from Carid.
The most recent, pic included 18x8 40 offset, will be ok with spacers in the front. They will be close to flush with 10mm. The other wheels I could have used spacers also but then they would have poked out.
Was sent non hub centric spacers from Carid. They sent 5mm and they still hit, so I doubled them up and 10mm works perfect.
Discount tire where I am buying the tires won't put non hub centric on I and understand as no one recommends using them.
I am getting ready to order hub centric spacers that will need extended lugs.
It looks like the back will need a little wider spacer to have the same flush fitment. Seems like the back wheels sit in more than the front stock.
I am ordering spacers now and wanted to see what width others have used to be even front and back? What the difference has been? Thanks

 

Before buying new wheels you need to ask the seller. What's the disk space.

Example below:

18x8 ET40 with 20mm spacer per side will be close to flush on the back. You can use bolt on spacers with studs pressed in.
If 10mm clears the front caliper then go for it...(you need spacers with extended studs in this case).

I already have the wheels. This is addressing the spacers.

 

Thank you. I might buy 15mm and 20mm for the back and send back what I don't need.
