Even with a 2"/3" drop, and running 14" wheels with low-ish profile autocross tires, my S10 is going to be pretty far outside the 1:1 height to track width rule.  I think about the only way I can get it within the rules is to use some bolt on wheel spacers, probably in the 2-3" range, and probably add a bit of weight.  Being as this is the challenge, and the truck is unlikely to see any autocross use outside of it, I kind of need to go cheap.  Will something like these likely be safe to use:  Ebay spacers?

I know they are allowed in general, but am still a bit nervous.  I don't want to be the guy who gets disqualified for losing a wheel, or worse, getting someone hurt. The car will probably be somewhat traction limited compared to some, as I'll be running likely 205 width or narrower tires on something that weighs around 3000 lbs.

I autocrossed a grand marquis a few times one season running 1.5" and 2" ebay adapters. I made sure they were hubcentric.  Was running 245 width cooper zeon street tires. Did not have any issues.

I put 3" spacers on a SRW class B motorhome.  Never had a problem.  Then put them all around on my Ranger.  Again no problem.  You should be fine, other things are far more likely to fail then a solid chunk of steel with lugs through it.

It's more or less just some aluminum and hardware- if you trust the aluminum, can you order without studs/nuts and add your own more legit hardware?

If I remember right, on an S10, hubcentric is only for locating the wheel while putting it on.  The wheels use angled lug nut seats, so all the loading is through the clamping force of the lugs.  I doubt I'll find hubcentric spacers at a challenge friendly price.

May be able to do that.  I think good studs might kill the budget, though.  Going to be trying to figure that out this weekend.

We have raced an entire LeMons race with our 1975 LTD on aluminum bolt-on spacers.  $99 for 4.  We do replace the spacers for the next race.

Be warned: aluminum spacers may come with two different lug nuts.  Make sure the nuts that have a larger contact face are used to secure the spacer to the hub.  Otherwise, the stress may cause the spacer to crack.  We had that happen once.

Studs are budget exempt, unless you are talking about your actual wallet budget and not your challenge budget.

I'm running those on the Vette. They work fine and seem well made.

I got 2" hubcentric spacers on ebay for the chevelle for around 110 shipped. Same ones you're going to need

Exactly except mine are not black and cost around 110 last year.

I've got spacers/adapters with studs in them on a bunch of my cars and have never had a problem other than finding a replacement stud that fits if one breaks.
