20's are on...O-Z & Yokohama
Got the wheels & tires slapped on today.
Wheels: O-Z Palladio ST, 20x8 +32mm
Tires: Yokohama Parada SpecX, 255/45-20
Rear clearance, as advised by CK6Speed, is very tight. The tire is just under the lower spring perch...whew!
Initial thoughts.... I'm really happy with the look. I thought 20's would be too big, but given the wheel style and finish I think they look right for the vehicle. Ride quality is a bit more harsh, but not overly so. Braking and acceleration suffer a bit. Acceleration more noticeably so, but braking too. Part of my commute is a stop at the bottom of a really steep hill...definitely more effort/distance required. I don't think this is huge, but it's certainly worth keeping in mind.
When considering 20's most vendors recommend 245/45's. I wanted a bit more sidewall, both for ride comfort as well as the look. The diameter is a theoretical 0.8" taller than stock. I haven't measured actual vs. indicated speed as yet, but the speedo/tach ratio is barely changed. With stock tires 2k RPM equated to just a hair under 70mph. Now the same RPM has the speedo spot-on @ 70.
Just starting to enjoy the honeymoon but thus far I'm really happy. I dig the look and none of the adverse effects are showstoppers.

Can't wait to see how it looks when you get the rest of your little projects done. Should come together real nice. How was the rear inner fender liner fitment? It should be pretty close.

Ha! Thanks for all your advice and for sharing your experience...definitely appreciated.
No worries with the fitment within the wheel wells - just that tightness under the spring perch (roughly 1/4" or so of tire actually fits underneath it...kind of a trip). I definitely don't know if I could be as courageous as you and run 255/50's, but that's okay. The 255/45's don't look too skinny...at least to my eyes.

. Lexus should add those as part of the lineup as well. Great job

Nice, real nice. 20's are the way to go.

Look great also close that fender gap a little more. 
The loss of torque is due to larger diameter and perhaps heavier rim/tire combo, but you gain more actual miles driven under warranty and resale value by having a slower odometer.
My recommendation is get BBK as soon as possible, it will improve the look better . Bigger rims tend to make stock brakes look small, BBK will get the brake performance back to where it was before plus more.

You're right on the torque loss, although I'm inclined to emphasize unsprung weight over the realistically marginal increase in rolling circumference.
I'm not sure I'll go BBK with this rig, but I do agree that the stock brakes look tiny inside there. I'll keep my eyes and ears open but it's not really on the radar screen right now.

What kind of Yoko's do you have? I love my Yokohama's on my TL.
