Wheel spacers in Auto-X?
OK, I was looking at another non-racing related thread and came accross these.....
http://riggedup.ecrater.com/category.php?cid=193985
I was wondering if using them on my Auto-X car would help me by widening my stance. I have always thought that a wider car would handle better (too many old Pontiac commercials? ). Looking at the design, they seem to be safe. I know there would be no clearance issues in the front. Maybe some clearance issues when turning in the front? Upsides? Downsides? Just seems intriguing.

A good alignment specifically for autocross, proper suspension components, race tires with proper air pressure would do a lot more than just moving the wheels outboard thru the use of adapters (those are not spacers).
As you mentioned, you would probably encounter some tire/fender/frame rubbing on hard corners if the car has any bodsy roll. But that depends on the tire width, height and what the existing offset of your current wheels are.
Depending on the sanctioning organization, adapters may put you in a different class or they may not be allowed at all.

Wider track width helps but you will change the scrub radius and will also make the car wider if they extend past the fenders (you have to drive a wider line in slaloms and offsets). I have used it to reduce understeer in stock class (front track width increase) but not on a corvette.

I run a 1/4" spacer for brake clearance in the front. The problem with the ones you show is they are not hub centric. There should be a shoulder that keeps the rim true to the hub at all times. With no centering shoulder the bolts and lugs have to take the load.

Pardon my ignorance, but what is hub centric? Can you show me a pic / graphic of something that IS and something that ISN'T? That way I can understand?

Don't have any pictures, but hub-centric basically centers the wheel up on the center "pilot" flange on the axle hub. Lug-centric wheels have tight fitting lugs (usually straight shoulder) that center the wheel on the axle hub.
The lug-centric wheels depend on the clamping pressure of properly torqued lugs to a clean hub/wheel face to stay in position.
HTH, and have a good one,
