Default Alignment Specs

Guys, getting Michelin Pilot Sports installed this week on my '01 vert and am also going to haved the front end aligned at the same time. Currently the car drives well but is wearing the outside of the left front severely. Was curious as to your opinions on the factory alignment specs. This is my daily driver, my main concern is not so much with performance as it is with tire wear and overall drivability. Does anybody have any first hand knowledge or experience as to the best setting(s) to optimize the aforementioned?

Are the factory alignment specs sufficient for what I'm looking for?

TIA

Thisis a link to a site that many of us use for the performance settings..
but you will note that they also have daily dirver alignment specs as well...
They have not updated them for the last 2 C5 years, but they are the same...

Get a four wheel alignment. It is worth the extra money in handling and tire wear.

If you want the max performance I would suggest going with just a tad (0.02") toe-in both front and back, then about -1.2 degrees camber in the back and -1.4 in the front. you wil get just a little bit of inside wear with these settings, but not so much that the tires will prematurely wear out. The greater camber in the front will also allow for a bit better turn-in...

FWIW I am running -2.1 camber front and -1.4 camber rear with 0 toe in or out. I wear pretty fast on the inside up front - faster than I like, and plan to reduce down to -1.4 next time I do tires. In the back with -1.4 the tires wear just slightly to the inside, and I see chords on the inside right about the time I hit wear bars on the outside. I also want to add just a tad of toe-in to help the car track down the highway...

Front Camber = -.75
Front Toe = 0
Front Caster = 7.9

Rear Camber = -.75
Rear Toe = -.01

This is what I am running and it handles like it's on rails. I do have Pfadts coilovers and C6Z sways, though. Also will give you minimal tire wear. On the street you will not notice anything from more camber except more tire wear. If you are going to hit the track then dial in more camber. BTW, camber helps traction in the turn. Toe in is what affects turn in. Toe's compromise is stability at speed vs quick turn in.

The left front can be affected by road crown also. If you live and drive on roads with a large crown then you should put some more camber in the front left.

Randy
PS If you are on the gas at all, please put some toe-in in the rear 1/8 inch total

Good call on the MPS's Vette Girl You won't regret it for daily driving duties...

IMO, a far superior wet traction tire than the stockers...

Thanks for your specs. I'll probably go with 0 camber since it is a daily driver.

You can go 0 but I would say go -0.5 on the camber, it won't cause any adverse tire wear and will keep a good contact patch under cornering conditions. also do the 4 wheel alignment, it's definately worth the few extra dollars...
