Limitations of Factory Eccentrics when Lowering

[GQM]

hey Fellas,

Was looking for a little input on the limitations, if any, with factory eccentrics when you lower the car. I installed MSS height adjustable lowering springs with Verus Camber hats. There was negative camber gain to about -2.5' in the rear and I am wondering if I will be able to bring this back down to -1' to -1.5' with factory adjustments or will I need aftermarket arms. Same goes for caster as I feel like I lost some caster at the front axle with the suspension. For FR cars I always prefer around -3' F and -1 to -1.5' R as a balanced setup that rotates easily and predictably if you feel like hooning about but can still be driven neat and tidy as well. Basically you pick your angle. I don't care about setting fastest times as that is not why I bought the Supra. I just don't want to go to my buddy's shop 1 state over and get it on his alignment rack only to find out I won't be able to hit my numbers with the factory adjustments.

Any help in advance is greatly appreciated!

Cheers,
Quinn

if i remember correctly, max camber is -1.9 rear with a stock configuration. i don't think you'll reach the -1.5 you desire

Do you mean minimum camber? Is that with stock height or lowered?

yeah sure, minimum

both stock and on lowering springs, i was told the same, -1.9

Gotcha, that's lame. So the follow question is, do you know which of the aftermarket offerings can bring rear camber down below the factory setting?

I read it lol. Didn't see anyone vouching for the Eibach, only the Verkline. Are you running them?

Reached -2.0 rear no questions asked, lowered on H&R springs

That's too much negative rear camber. The question is how much negative camber can you take out with factory eccentrics, not add.

lmao. yeah buddy. you can reach -2.7 on stock configuration. that’s not the topic here

no sir. but if we’re talking about the same thread, razorlab was complimenting the design when compared to SPL. i think for a street car, you should be more than fine with eibach’s offering rather than verkline’s. but up to you!

i like my alignment so not interested hehe

I could also vouch for Eibach if that helps. We use their anti-roll-bar kits a lot on our cars and for customers, because they have TUV, which is a BIG thing in Germany. Other parts from Eibach don't have it, so we can't use it. Most people who ordering a full track-pack still want Verkline, because it's the best you can get.

But after all, nothing wrong with Eibach at all - and like I said before: it always depends on what your plans are in the future.

OEM specs according to service manual:

Front
Camber: -1.75* +/- 0.50*
Toe: 0.12" +/- 0.09"
Caster: 7.58* +/- 0.50*

Rear
Camber: -2.00* +/- 0.42*
Toe: 0.10" +/- 0.09"

Issue is, they rarely arrive with the alignment being correct.

I use the BG Racing alignment kit with a pair of QuickTrick turn plates

That being said, I do have a few bookmarks saved from our resident track rats.
