Default Corner weighting vs. Regular alignment

Hey Guys,

So I'm going to be bringing in my 03 vert in for an alignment as I recently put new tires on her. Talked to a shop and they mentioned both a basic alignment and a corner weighting alignment. She definitely is a fair weather car and am wondering if corner weighting alignment would be overkill for a leisurely cruiser.

Thanks,

Les

is this a high end shop that does race cars? very unusual for a normal shop to have a set of corner scales

what specs were you going to set the car to?

The shop is Blackdog Speed Shop a very highly thought of shop (in the Great Lakes Forum). They do performance street, competition/track and regular drivers. The shop manager was very quick to respond to my email.
I've never had my vette aligned so I don't know squat about the specs?

I'm a bit curious how this works. Given the way the C5 springs work, I don't see any way to adjust corner weight independent of ride height the way you can with coil-overs.

it's not as easy and you have a limited ability to do so. what happens...as i found out, with leaf springs is when you raise or lower one corner, it impacts the other 3 with the primary impact being the wheel on the other side of the spring

if you dont track the car corner weight is probably overkill

a good street alignment i like is

front: camber -.9deg, toe .02deg in each side
rear: camber -.7 deg, toe .05deg in each side

caster set to factory which is around 7deg, to do a road crown caster set one side will be half a degree more than the other-ish, forgot which side you favor but they will know

Corner weighing just makes sure equal weight is distributed to each tire. Only really needed for the guy looking to get the very most consistency in racing. For the daily person not needed

You want caster to be .30 to .50 higher on the right to offset road crown

Won't it tend to drift left on level roads like freeways?
(Thankfully the roads aren't crowned here. )

seaboard states where roads are crowned to the right for water evacuation we give the caster spread. Midstates not necessarily needed.

I know (or at least vaguely remember) what you mean: I lived in Orlando when dinosaurs walked the earth, Disney World was a swamp, and McCoy was an Air Force base.

If you don't track your car... you may not be very happy with the way the cars stance will look after corner weighting.

Just saying...
