Default My tru-turn experience

I installed the complete Ridetech coilover and tru-turn system on my '69. Prior to ordering new wheels and selling my old wheel & tires I did a test fit - (coilovers temporarily not installed) - with a 275/35/18 on 18x10 wheel with 5.75 B.S. (This wheel and tire was being used on the back of my car w/ a small spacer). I set the camber close to zero with an angle gauge. I immediately discovered that combination would not work at all unless I wanted a very high ride height - not desirable. The tire touched the top, horizontal, outer part of the fender at any where close to full lock. The fenders would have to be flared to provide clearance - not desirable. I then ordered 18x9" wheels with 5.75 B.S. and the setup looks OK with the 275 tire. My Camber is set to -0.5 deg and is about all I want to go for good tire wear. I loaned the 18x9 wheel/ tires to 2 friends that were also in the process of installing the tru-turn on their '69 Camaros. After testing, they both went with 18x9 with 6" B.S. They are able to run their Camaros about 1/4" lower than my car and are happy with that combination. A few months ago I tried lowering my car that low but then heard rubbing during parking maneuvers and discovered the paint chipped off the fender where the tire was making contact. I raised it back up 1/4" and that is as low as it can go. Also, both sides of the car have very close to the same clearance, no more than 1/8" difference.

Recently Ridetech built that high end '69 for Goodguys and used an 18x10 on the front but I have no idea how they made it fit, or if they run lots of negative camber, or how much backspacing they used. Will they be able to leave it at that height and really drive it on city streets, parking lots, fields, etc?
