hmm need to check the exact specs, I messed with the alignment a good bit because I tried the Verus camber plates and they were so loud I removed them the next day and in turn had to redo the alignment. car actually drove the best after it was lowered without an alignment; once I got it aligned I tried to "fix" the stuff I thought would help but it only made it worse; after messing with it a few more times just kind of gave up. Came to the conclusion that while I love this car and it is amazing, the chassis just isn't the best for a really precise direct steering and suspension feel. I am going to get it realigned in a few weeks again probably as one of my favorite local shops is finally getting a machine and I really trust his input.

I think you’ll be mega happy when you do. Text my cell or PM me if you need a good reputable shop on your coast.

Maybe reduce the rear camber to -2.0 to -1.9 and maybe 0 out front toe. On my car with springs camber plates and sway bars I have my Front -2.2 and rear -2.0

I was gonna mention the same for the front toe. Typically one shouldn't want to run toe in up front. 0* or even a hair of toe out if OP is also enjoying some twisty roads.

I wanted my car to handle corners and have more direct steering after tracking it stock. I installed Verus camber plates and HKS springs with Eibach sway bars with AFE endlinks and have an alignment after break in of the new suspension. The shop did my alignment did a great job. My car now handles awesome and steering is alot more direct and precise. I am enjoying this car alot more now then when it was stock. I had noise with the camber plates once the suspension settled the noise became less and less and actually not noticeable at all. My goal was to concentrate on suspension before doing any power upgrades.

Always suspension, brakes and aero before power.

im still running toyota tuning and really dont see a need for more power yet. Well you can always have more power but its really not needed these can cars can be set up to get very quick lap times with stock power

It may be a radial defect in one of the tiers. This happened to me with brand-new tiers. An easy way to test is to rotate the fronts and do a pull; if it pulls to the "other" side, then you know the tiers are the problem, and you need Toyota to get you new fronts--or possible rears.

also wanna check the same size spacers are installed between left and right side, if you did something like 13F 15R, it might get mixed up

Thanks for the suggestions everyone, I contacted other customers who went to the "race" shop I went to and some of them have had problems after with loose suspension parts.. In addition to all this, my suspension rattles over bumps. I think there are parts that are loose below the car.

Hopefully I can have it inspected before it goes into storage this weekend.

Did you ever find a solution to this pulling under accel issue? My 23 MT exhibits this although not as bad as what you’ve described.

I ended up sorting it out with an alignment, although the first alignment was technically good.

currently looking to sort out the lane wandering issue. I’ll be installing traction arms, diff case brace, and some other parts in the spring to work that out.

If the first alignment was good, what did you change with the subsequent alignments to fix the issue?

the city I live in has the worst roads in North America, only drunk people drive straight. After driving over a few large dips at speed and hitting some bumps (that are an entire lane wide) When I examined the issue the alignment had changed to this:

.15-.20 toe in on both rears will have that car going straight on WOT.

That sucks man! Can they lock it down? And are you able to avoid most pot holes or go another route when taking the Supra out?

Interesting. I had the same issue. The suspension was stock and it pulled with the stock tires and wheels, but it felt way way worse with the TE37 + 305/35/ZR18 RRRs in the back.

That and the bumpy/bouncy feel above 120 mph. Something is off with the stock suspension. I don't feel any of that in any other car, not the M4 not the 911.
