2001 GTS Alignment

[martyb]

While my car was in the air for the winter cleaning, I noticed the inside edge of each front tire wearing badly. I looked at the alignment specs that the last owner had, left front has -1.9 camber, right front has -2.0, seems pretty aggressive for the street. I know the last owner did a few track days with the viper club, but I do not track the car at all. My question is, can I just knock the camber down to -.75 on each side, or do I need to get the entire car realigned?

Thanks all, springs almost here in Chicago

Baz had some numbers from his alignment. I used them. I can post them tonight if someone doesn't have them. Id do them all personally since things change.

that is an aggresive street alignmant as that pretty much what I run. You could take it down to -1 or so. What were the backs @?

 

[martyb]

left rear -.9, right rear -1.0

this is an area I could learn more in, I'm pretty good with aliments, no matter what I take my cars in once a year even with limited added driving miles and have it put back to factory spec, I would like to learn what is acceptable "out of spec alignments" for different driving applications. I will be reading that link

I won't get into the toe which should be pretty much neutral, the camber I had my 2000 Viper set at for everyday driving and track applications (street/track) was -1.3 in the front and -0.9 in the rear, it was a happy compromise.

My car will never be driven in an auto cross or track event, mostly a highway car. Just wondering if I can leave the rears alone and knock out 1 degree of camber on the front end or align the entire car?

I'd put the fronts @ -1 and the rears @ -.75

 

[SoCal Rebell]

I'd put the fronts @ -1 and the rears @ -.75

I went up to -1.9 F and -1.3 R when I started tracking more, the car was still streetable but was very "darty", it took a while to get used to it. -1 F & -.75 R is probably close to stock settings.

Had similar Qs before, here are the OEM specs and what I will go with for "aggressive street driving" (without eating through my PS2s within about 10k miles)

Service manual for a 2002: [pm=plusminus]
CAMBER...............front -0,20° pm 0,20°.............rear -0,50° pm 0,20°
CASTER................front +6,0° pm 0,50°.............rear +1,0° pm 0,50°
cross caster (maximum side-to-side differential) 0,50° front and rear
TOE (per wheel)...front +0,05° pm 0,04°...........rear +0,10° pm 0,04°
toe maximum side-to-side differential 0,04° front and rear


Conclusion (good for me)
Front:
Caster: +6 deg (stock)
Camber: - 1 deg
Toe-in: 0.04 deg (per wheel)
Rear
Caster: +1 deg (stock)
Camber -3/4 deg
Toe-in: 0.07 deg (per wheel)
