Your tire hits the outer fender because the 265/45-18, at 27.4" tall, is about 1.8" taller than the 25.6" tall 275/35-18 tire that we (and most others) use. It hits the subframe at full lock because you've selected the wrong wheel back spacing by 1/2". Our printed recommendation for back spacing is 5.75".
If you install the correct parts on the car it will fit just fine.

I’m not the smartest guy at the track … but when he goes home … I’m still there testing, tuning, learning & getting faster.
1st of all you cant make a hard BS recommendation because you don't know what my track width is. Depending on what brake setup people have the track width can move by as much as 1/2" or more.
2nd, and most important - If you look at the pictures the fender is practically sitting on the tire. adding an extra 1/2 of backspacing in my case and the fender will be sitting on the tire.
Basically I can not move the tire out towards the fender any more.
where do you live? if you are in dallas i would be glad to look at it for you
Thank you for the offer Randy, but I sold the subframe with the ridetech setup. I gave up on making it work and considered buying rehoops for the front wheels, but somebody bought the subframe so i went ahead and bought a DSE subframe. The DSE is workable with my existing backspacing.
OK
23 pages later and I am glad I have not ordered my ridetech system yet. Quick question about the set up for my 69 Firebird Conv. First I am not interested in autocross just want good handling on the road and adjustability in ride height. I am going LS 480 or 535 and automatic, while I want to run a larger front tire, I really do not care to have bragging rites for stuffing in the largest I can. Will this system work for fairly easy for a guy with my goals. I do not want to create a nightmare when buying parts etc.
Thanks
