will i have a fitment issue with these Status Knights on my 2001 gs300???

20x8.5 for front 5x 4.5 blk/mach
20x10 for rear 5x 4.5 blk/mach

No.

You will not.

Thanks... came across a good deal and wanted to know if i should pursue it

If you run 305/65/20's with a 0 Offset wheel you will. Tire size and WHEEL offset matter.

Lookey here: Wheel Fitment Guide 2GS/IS-01-05/SC430 Wheel Fitment Guide 2GS/IS-01-05/SC430

thanks... I did see this thread, but alas, i know minimal about tire sizes Hence my question

LOL the blind leading the blind. Not if they are lower than +20 offset :P

im running the same setup with no rubbing issues at all and i'm pretty low.....

yeah... thats my inspiration!

^^^ thank u sir...is your Gs black too?

You are? From the photos it looks like you're running the same size all the way around??? I thought the 10" wide rears have a way bigger lip??

^^^^that picture that u posted is a 22" wheel...the lip on the 20s isnt that big

oh my bad... man the website can be a little misleading

Offset plays a role on lips also.

yeap... black on black.

No i actually looked up the rims and the offsets for a 5x114.3 pcd and for the GS/toyota
