This isn't for the S-10 platform, but I thought it was interesting enough to post.

It uses a watts link on either side of the axle instead of what would be the upper link in a four-bar setup.  Also, the watts links arms are not equal length, which would give some fore-aft movement.

I have no idea if this is actually a good idea or not, but it might solve some packaging issues.

i went up all the way to 110" in ~1" increments, and then now i'm 'filling in' the gap where i think is ideal.

haha yea, the bent flange went the wrong way on the stock bracket too so i had to "flip" the flange.

took a lot more effort to make it look smooth and all the welded together bends tangential because having it end up in steps looked terrible

I'm not an expert on the Corvette wheels, but from my reading it sounds like most people run a 2.5" spacer with good luck. The 1st generation of trucks do have a bit narrower of a body than the 2nd generation, so keep that in mind when comparing tire fitment.

Good wheel and tire fitment can be a bit of a trial and error, but it isn't too hard to do. Honestly I recommend drawing it out while looking at some backspace drawings to get a feel for what all the different dimensions do. I almost always turn to google to find a diagram when I'm talking wheel offset and backspacing.

Take some measurements of your current wheel/tire and see what room you have to grow or shrink. I've taken white posterboard and wrapped it around the tire to simulate a wider wheel/tire and measure what that looks like.

Also most reputable tire companies will publish actual dimensions of their tires on the recommended wheel size. The 235/75R15 numbers are often more of a representation rather than an exact number, so the actual dimensions can help make more educated decisions.

I did all of that for my current setup and only have minimal rubbing in the rear on the one side. Could have gone another 1/8-1/4" larger spacer on my wheels and have no issues, but the rubbing is so rare I don't fret about it.

I'm would  be interested in a wider tire .I just doint know were to start  to look at wheel ,what back set ,do I need spacers???
I'm trying to figure some sort of budget .
love the stance on yours. what are u running .and thank for the help!!

I'm in the posses of building a 85 reg cab short box for Autorcoss and some street driving,I'm new to s10 so I'm a little lost on were to start  The  truck is going to have ls1 /auto out of WS6 bird ,we have UMI corner max kit for front , and JSM  3link in rear the rear is out of 01 blazer 8.5
I'm hopeing for some idea on wheel, The plan is  to run 275/40 /18 I would like to try a corvette rim if it could fit .
Thanks for the advice
