does any of you know if these wheel size will fit a 01 ls 430
18×9.5 with an offset of positive 36
19×12 with an offset of positive 50

 

The first wheel should fit fine depending on your tire size.

The second one won't fit without a ton of fender work.

 

thanks for reply

 

x2 on the fender work...but it'd look incredible once done!

 

not looking for more the fender rolling, thankyou

 

Actually you'll be okay with a 12" +50mm, as it will sit 5mm further inward than my 10.5 +26mm rear setup with just shaved fenders.
Those 9.5 +36mm will be fine on the fronts also with room to spare(depending on ride height and amount of camber).

If anything, you'll run into clearance issues on the inside(rim/tire to suspension), as there will be 43mm less clearance than my rear setup. Might fit, might not on the inside as I haven't measured my inner clearance to give an educated answer.
