Getting some suspension work done soon including camber plates, and there doesn't seem to be much info here or in the G80 forum about alignment settings. This is a weekend fun car, so I'm not too worried about how it drives on long highway drives or anything, it can be a little aggressive but I don't want a track alignment either. I'm thinking -3F/-2R, zero toe front, and a smidge of toe out in the rear. Does that sound about right?

That should be plenty for fun road use. If you track the car you’ll want a bit more camber

You’d want toe in for rear not out btw

Toe-out in the rear can make the car very responsive, but also impart a feeling of instability in many cases, accentuating tramlining. It is rare to have rear toe-out outside of an aggressive track alignment.

Go-kart alignment not always best alignment. Can be fun though!

I chewed up a high dollar set of tires in a short time running a track alignment on the street. Squirrelly doesn’t even begin to describe it. Holy turn-in though. Addictive. Extremely boring once you go back to a proper street alignment.

In doing more digging, slight toe in in the rear seems to be what most people do. Is that a better choice for a street car?

Yep. Under compression your suspension tends to toe out Some cars more than others

You want zero toe front and a slight toe-in in the rear for stability.

How much toe in in the rear? .1 degree or so?

Do you think you can generate sufficient lateral forces for the tires you can consistently use -3 front camber? That much negative camber will impact tramlining and braking performance downward.

[tylerdurdem]

Consistently? No, but this is a weekend fun car that is pushed on most trips, so while road manners certainly aren't of no concern to me, they're less of a concern for me than for people who are dailying their cars.

You misunderstand me, I think. What I meant with 'consistently' is will you be able to generate sufficient lateral forces during most cornering on street tires (assuming) for the -3 camber to give you its benefits? Sufficient lateral forces on street tires equals to somewhere in the range of 1.0 to 1.1 g sustained through cornering. If you do not generate that high of sustained lateral forces through the corners, then you won't be able to use most of what the tire is there to offer you, meaning you will actually have less grip because of too much negative camber.

Anyways, the whole point I am trying to make is don't just set the alignment to something because the Internet tells you to do, observe your own driving a bit, take few measurements and then set it. There is a g-meter on your dash, look at your tire pressures after a hard drive, observe how your tires are wearing, and then figure it out. In my own experience on the G80, I have -2.2 on the fronts and -1.9 in the rear and for street driving that is even too much. On track I get by with those, but can use -2.5 in the front and -2.1 in the rear. I am not able to generate sufficient lateral forces to use anything beyond those numbers with my driving, at least not yet.

Good info, thanks.

That is too much camber for the street, you won’t see any real benefit. An aggressive street alignment would be around -2.0. Zero toe or toe out on the front will make the car more eager to turn, but won’t be as stable in a straight line. You always want toe in on the rear.
