As for the motor rebuilds, we just couldnt get the motor to hold together. I had the best mechanics around working on this thing. We'd get it all back together, it'd run great for about a month, then WHAM! It would spin the lower bearings. We mic'd the ENTIRE engine, and were maticulous about it. But it did no good. I think the longest a rebuild ever helt was about 6 months. The shortest, 2 weeks. GRRRRR!!!!!!!
As for the tires, right now it has low profile 14's on it. We are stepping it up to 16's as soon as the paint is finished. We've been hanging out in tire shops for the last 2 weeks looking at tires and rims, and have narrowed down our choices.
As for rubbing... Not with the 14's, and shouldn't be a prob with the 16's either. I found a great website where a guy has actually made a tire size calculator that shows what all you can replace the tires on the 108 with. He also features a dozen or so 108's that he has already changed over to 16's, and goes in to good detail as to what spacing you need to achieve the right fit. Kudos to him! Also, when we installed the corvette rear end we lifted the rear of the car by 2", just cuz we wanted to. I like the look of it too!
Here's the link to that site if anyone is interested:

The is a wealth of info on there as far as converting your tire sizes. I don't know this guy.... just stumbled on to his website by accident. I'm sure glad I did tho! Hope it helps some of you as well!
I'll try to get some pics to share with you folks ASAP!
