OEM Wheel Alignment and handling upgrades

[Muzzie]

Does anyone know the RHD OEM Wheel alignment measurements? It may be the weather, but the rear end feels a bit twitchy. I was considering upgrading the strut brace, chassis brace and roll bars. Has anyone in the UK done these upgrades and what was the result?

You mean what is the alignment supposed to be, or what is it in reality? These cars (and most BMWs from what I gather) are very poorly aligned from the factory, and getting it re-aligned to factory specs will do wonders for the feel even if you’ve made no suspension modifications.

Yes, I took the car to a garage to check the alignment and it was running 0 deg camber front and rear. This didn't seem correct, but I was told this was within Toyota's spec. I'm no expert, so I didn't want to mess around and end up in a ditch. I just need a good road setup. I can't find any info for a right-hand drive car.

Hi Paul.
You might find this interesting,

I have a similar issue and not just in the wet.
I also have been concidering getting the alignment checked by a specailist

It would be interesting to see if all supras are set up like in the video, for me it's a quality control issue either from factory or dealer...

I had an alignment done at A Reeve performance here in the UK after seeing quite a few people with bad factory alignment on Facebook. I don't have the measurements to hand but it's sorted out the rear end squirming a lot under hard acceleration

I had an alignment done to the same spec as what was done by Manthey/Raeder Motorsport in the video. It’s transformed the car’s handling. My factory alignment was absolutely wonky, and it seems that whatever system my local garage uses, it doesn’t have the factory alignment specs for the Supra yet.

Here is mine…

Same here, none of my local garages has the factory alignment specs for the Supra yet. The Toyota dealership emailed me this

-1°50' +/- 25' (-1.83° +/- 0.42°) *7 -2°00' +/- 25' (-2.00° +/- 0.42°) *8

0°14' +/- 12' (0.23° +/- 0.20°) *9 0°14' +/- 4' (0.23° +/- 0.07°) *10

2.7 +/- 2.4 (0.1063 +/- 0.0945) *9 2.7 +/- 0.8 (0.1063 +/- 0.0315) *10

As I'm not a car mechanic, it didn't make much sense. I assume the OEM setting is:

-1°50' camber on the front, -2°00' on the rear and 0°14' toe-in front and rear. I'm I correct?

I've had the car four-wheel aligned, and I'm confused. Two local garages have told me not to deviate from the Toyota spec and that the front camber can't be adjusted. However, the front camber on my car is amber on the alignment reading, so I'm unsure if this would affect the handling?

I have tried to increase the toe-in on the rear, and the car was undrivable. So I've changed it back to the stock setting, and I'm back to square one.

My issue is that if I give the car some throttle in a straight line, the car wants to turn on its AR$£ and spit me out!! I know the roads in the UK aren't the best this time of year, but I have to be careful as the car is unpredictable. Any thought?

Also, I've been thinking of upgrading the strut bars, rolls bar and lowering springs, will any of these help with straight-line traction?

So what are the settings in the video again? He didn't advertise any.

Hi Abdul.
I think the set up information you are after is at 9 minutes 16 seconds into the video.
