Aligned after new tire install. Kept pulling right, back on the rack for adjustments, still pulled. Checked with me in the car. Still didn't feel right, he was thinking radial pull could be the only thing left and swapped sides. He did suggest upgrading the control arm bushings for better tire wear etc which has been well talked about here. Above is the print out. I am currently all stock suspension. Any thoughts would be appreciated! Want to get the most out of the tread as we all know tires aren't cheap. Thanks again!

 

I’ve had tires that caused a pull. I got new tires and the pull went away.

 

Front and rear Toe are not in check,
-Front try to be around 0.00-0.02 out
-Rear 0.10-0.12 in
even both sides

 

Front toe is bizarre. The numbers should either be both positive or both negative. Never one pointing out and one pointing in which is what you have on your sheet, and it doesn't surprise me at all it wants to go right with the left wheel toed in 1mm and the right wheel toed out almost 1mm. Positive angles are toed in, negative angles are toed out. Unless you really know what you are doing, toe should be between 0.00 and 0.04 degrees on both sides.

Left/right front camber is jacked because the subframe isn't properly centered, and caster is also off because the subframe isn't centered.

Rear toe is also bad and should be symmetrical, as mentioned above, Should be +010 - +0.12 degrees. Thrust angle should be as near zero as possible, and even though it's better, it's still not very good.

 

This might help too… once you get the front subframe centered as @lobuxracer mentioned

Appreciate the advice, I knew something was off. Going to have it re done at another shop.
Might have Lexus look at it as unfortunately I think I have the valley plate leak. Fortunately it is covered under Lexus certified warranty
never had an issue with coolant level. but when washing and detailing, noticed that the level was below the low line. filled to the full line while engine cold. after +- 300 miles was back down to below the low line. Car is garage kept and no visible signs on the floor or firewall. So based on all the info sounds like its valley plate.

 

I have an issue with the caster being off as well on my car when I got an alignment? Does any company make alignment solid collars for the subframe? I know some other cars I have owned companies make these that basically takes the guesswork out of aligning the subframe. They do transmit a little more vibration though so not an option for everyone if they even are available.

 

Spoon and some company called Magic collars.

 

Be sure your subframe is properly positioned before you change anything else. Both camber and caster are affected by subframe position. Wheelbase left to right is also problematic if the subframe isn't right.

Every chassis tuning book I've read tells you to first square the car. If the axles aren't parallel and centered on the car (assuming the car will turn both left and right), then nothing else is going to be consistent. Sprint cars are different because the axles need to be parallel, but not on chassis center to help the car turn left. Our cars need to be centered.
