What fitment would you recommend for the 19” T1-S on a GS350 AWD?

I am having difficulty getting any info from Work.

Front:
19 x 8.5 +40(38) – r-disk
-- assuming high disk due to big caliper

Rear:
19 x 8.5 +35(60) – standard a-disk
Or
19 x 8.5 +30(72) – o-disk
Or
19 x 8.5 +38(64) – o-disk
Or
19 x 8.5 +25(70) – standard a-disk

I will be dropped on DF210’s. There are too many options for the rear. I was able to get help on the front wheel because I was informed to play it safe and go with the high disk option. The rears are another guess…

Any suggestions on how to choose a rear wheel based on the offset and disk options from work?

 

Anyone? Is it because I am going with an 8.5 wheel in the rear that nobody seems to know how to spec this? Every wheel manufacturer has staggered specs for the GS350, so all their catalogues have offset recommendations for a 9.5" wheel in the rear. Nothing specific for 19x8.5.

Should I post this in the wheel and tire section? Any clublexus wheel sponsors want to help? I just see so many rear wheel offset options and need help so I don’t order the wrong wheel.

Rear:

19 x 8.5 +30(72) – o-disk
Or
19 x 8.5 +38(64) – o-disk

--- dropped on DF210's

 

Ok, I have figured this out myself - with an on-line calculator.

I went to Wald and saw what the rear wheel recommendation was for a RWD. The catalogue said 19x9.5 +43

If I compare that to a 19x8.5 +30, this wheel will have 26mm more clearance (the inside of the wheel to the strut housing), and have exactly the same outer position. So the 19x8.5 +30(72) will be good to go, even with an aggressive drop.

I'm ok now. Thanks for listening / or allowing me to talk to myself
