Any SC400s with 18x10?

Forced air induction. Cute. It was the unsprung weight that kept me away from real steamroller sizes, 41 offset, that's beautiful, lookin' forward to a pic. As far as the 'blow back' , didn't know if you were trying to be clever again, but anyway my car was fitted by the dealer with discrete little splash guards, they have been 100% effective at stopping that problem, though it's not as if this thing blazes the tyres apart. That reminds me, Art, go look at the suspension threads, I just posted a little thing about the fun I had last night with this luxury car, handles much better than I would've thought when you really push it.

Red93sc400,
Thanks for checking that out. After you get them on, let us know if there happen to be any fitment issues. Being that they're from Tire Rack, I doubt that will happen.

Hey, post a nice pic of those discrete little splash guards. Are they a Lexus item? Let me know ok? I think I may be needed em. I will check the suspension threads. Were you out in that cold??!! Sheesh.
I was watchin' our guys devistate the world in Half Pipe Snowboarding. Gotta love it. A ragged dude from NJ came in second and another dude from VT came in first. The other bronze was from a guy out west in Colorado I think. Just awsome.

Here you go, Art. This pic is with my chrome oe 7-spoke/ 225-55-16 winter stock, but they protect just as well with the 18's, plus as I said, they're unobtrusive. The dealer fitted these, as well as a Bene Vento deflector, gold pkg, wheel locks (replaced w/ Gorilla spline-drive), Lexus cel, and tint.

Hey Lexluthor:
Those are not too bad at all. I may just have to look into a set of those. We, here in the Northeast, have to take such drastic measures... like adding side spray profilactics to our cars. The guys down south and in the far west are saying to themselves....
What the F?&^ are dee's two guys doin'
Hey, ya's gotta do,,, what ya's gatta do...
(translated... drive a mile on our sloppy roads and youll put rubbers on your car too.

What's the smallest width that you can safely put 275's on? Is a 9 inch rim okay?
Also, watch low offsets on the front. Factory offset is like 49 or 50. If you drop the offset too much you end up moving the steering axis outward which plays havoc with your alignment and directional stability... The car will wander all over the road, follow ruts, and behave horribly on crowned or worn asphalt. I know first hand of this problem. If you have the option of a wider wheel with the correct offset, I'd go that route...

What offset is too low? The guys at Mackin Industries gave me an 18x8 offset +37 for the front. 18x9 offset +38 for the rear. Please tell me that's okay...

You want the section width of the tire to be a little larger than the rim width for best protection against curb rash. A wider wheel rim will also support the tire better which improves handling.

You can follow the wheel guide here:
www.datapathusa.com/scott/wheels.html
This guide was intended for the Supra but is close or identical to fitments for the SC300. All the geometries should be the same. Wheel well clearance is similar if not identical. I did not make the guide... It was created by a member on the Supraforums board.
As Clint mentioned for 10" wheels, on the rear you want an offset around the high 40s... 45-50 would be ideal.
For the fronts, the further away from 49 offset, the worse your steering accuracy will be... Simple as that. I did some homework after incorrectly putting on 40 offset 8" wheels on the front of my car. It pulls all over the road. On flat, new roads, there is no difference, but when you have a crowned or worn surface, and when you move the steering axis outward, you end up putting a yawing torque on the wheel. This will manifest itself like torque steer in a fwd vehicle, only it will happen most of the time on worn pavement and be especially noticable on braking on worn pavement. As a comparison, I swapped out 49 offset 8" wheels and the tendancy to torque the wheel out of your hands went away.
Using the guide, the ultimate goal should be to fill the wheel well completely, while still maintaining near stock offset with no rubbing. To do that you'll need around a 9" wheel in front and a 10" or so in back.
