Default Wheel Alignment analysis


I bought my 28500 mile 2007, base C6 a couple months ago.
It came with some reciepts including this wheel alignment sheet from when after the E-Force supercharger was installed. The installer added what looks like 3/16 shims between the engine cradle and the frame per Edelbrock's installation instructions. See pic



I have never driven a Corvette until I got mine and have driven it only about 100 miles so far. I have no idea how a Corvette is suppose to feel on the road. The car came with brand new tires and show no visable wear.
My DD is a 2017 Ford Explorer-big difference, no comparison.
The car tracks straight with little to no pull either way.
When weaving lane to lane in & out of lanes it feels like a go cart with no play between left & right. Im thinking it should not be so tight.
Maybe you alignment techs would assess the alignment specs, see what you think?

Thanks Much

The alignment looks good for the street. The Corvette should feel like a gokart.

Yes, it was aligned for street driving.
Thanks for the assessment.

Caster is spread a little, and both F&R camber are spread pretty far side-to-side. The way they are set would tend to make the car drift left. At least they got the rear toe even, so no thrust angle pushing the car to one side.
F&R Toe looks reasonable, and caster is good anywhere within those numbers... it has a little spread, nothing dramatic. I might set it spread around .3* that direction, to help a little with any road crown.
Middle of the camber spec is around -.5* F&R. Depending on your driving style, that might be a good value. I'd like to see them more even, but I doubt you'll have issues.

In my opinion, a go kart is fast handling, loose, and twitchy. They are corner carving machines. So you say it handles like a go kart but then you say it’s tight? To me, tight mean understeering in race lingo.

For reference here’s my alignment. It’s still a street driven autocross car so I didn’t go crazy with more toe out to help it steer quicker.

The front camber should be even and not positive. The caster split is ok on a street driven vehicle the way they have it. The right side should have a greater number to compensate for road crown.

Looks *pretty* good, but far from a targeted street spec. I'm attaching Pfadt's alignment guide for C5/C6, here's the snippet of DD Street. Mostly I see that you're rear toe, camber, are OK for all street, but not enough even for mild performance.
