Has anyone tried these alignment specs on a SC300? Is it good or bad?

Those settings work great, tons better than the stock reccomendations, but to keep the toe-in closer to zero without ever going into toe-out would be even better. Those big tires tend to drag, slow you down, also will help with wear.
For highway driving, the camber could be less also; these cars have great suspensions.

Personally my alignment is done at the following:

Front:
Camber: -.5*
Caster: =3.0*
Toe: 0.00*

Rear:
Camber: -1.1*
Toe: .2*

Thats for "neutral" tire wear, though I must add that I do NOT drive aggressively and if I did the values would be very close to those in the link. My reason for posting this is to bring attention to the fact that your alignment needs to be adjusted for driving style. If I drove agressively I'd get outside tire wear, thus the need for more camber, if I had more camber I still drove like a sissy, then I'd get the inside camber wear that everybody thinks is a "good" thing, but is really a sign of an improper alignment.

mine are very close to the specs given on that page, but I added a little more neg camber... -1.3 front, -1.75 rear...

handles nicely, and tire wear is very acceptable...

no complains here...

My sc300 will be on supra TT wheels + Tires (245 front & 275 rear) if it makes a difference .

Is there anyway certain alignment settings can cure "bump steer" on a lexus sc300 (stock suspension) with mkiv Supra Twin Turbo wheels (17in wheels with front 245 tire and rear 275 width tire)? I had my car laser aligned to stock sc300 specs and I still get some "bump steer."

Current Alignment:


What do you more experienced folks with supra TT wheels recommend I change in Alignment settings?

im running the same wheel and tire set up on my SC. im replacing the control arm bushings in the next week or two, along with an allignment... since i just put tires on. ill be aligning it at work. my rear is about perfect for tire wear... if the old tires are still there tomorrow, ill snap a pic. i drive the hell out of my car from time to time, and the rears had very even wear. ill check the specs when i do it, but it will be 2 or 3 weeks.

Wow, you have positive camber up front?

I realize it's within specs, but definitely highly not recommended...

I would start there, get the fronts to about -.5 degrees.... That should be a lot more drivable... I also like alot more caster... My caster is maxed out on stock adjustment at 3.5... Since my first post in this thread, I've went a lot more aggressive, and every little bit of negative camber you can get helps the handling immensely... (so long as it's balanced front and rear)

try to add ballast too on the driver seat, I weigh 160 so I put weight ballast that much on the driver seat, and about 1/2 full gas tank. This way the alignment is more accurate.
