Hmmm. A standard 8J X300 wheel is et33, so you only 'need' a 2mm spacer to get these in the right place. Probably not what you wanted to hear! TBH they look like they're a higher offset than that, but if you're sure that's what the stamp says... You did look at your actual wheels, not just that pic? They may well have made more than one version!

225/60 r16 is 676mm, 225/55 r16 is 654mm. Both standard fitment on different X300 variations AFAIK.

235/35 r19 is 647mm - so you can go bigger than that with no probs if you get the offset right first.
245/40 r19 is 679mm
245/35 r19 is 654mm

 

Got the numbers from behind the spokes on mine. But something doesnt add up cause there is 1" 1/2 , distance. Im not convinced ill like the 32mm spacers or that they will fit without some wheel rub on the fenders. So 25mm would be best imo. Too bad I cant go to a local shop and try various spacers.

 

so after a very long wait due to the spacers getting lost in the mail they finally arrived. here are some before and after pics. i am not yet liking the looks i think i went too thick with the spacers at 1.25"

 

the hub caps.


i used this image. just resized to proper fit.

 

Much better looking IMO

 

and springs finally arrived. now need to find a nice walkthrough on installing this without mayor setbacks. im guessing its possible to install them using a regular jack stand?
