Rear Wheel and Tire Fitment - Dimensions and Setups

I think we get into several conversations a month over what wheels and tires will actually fit under the rear fenders of the Cougars and T-Birds.  One thing that has not been done or at least that I can find is a thread that people post wheel & tire combinations that fit under the rear fenders as well as the rear suspension makeup.  What I think we need to do is post this information up so that a person can get a better idea as to what works and even what does not work but remember that pictures also help people get a feel for how it looks.  I'll start with what I have on my '83 Bird.

Car Info - 1983 Ford Thunderbird LX 5.0 Base Model

Rear Axle - '87 8.8
Stock or Aftermarket Lower Control Arms - Griggs Racing Adjustable LCA's with no spring perches, length adjusted to stock T-Bird dimension
Stock or Aftermarket Lower Upper Control Arms - Global West Adjustable UCA's (T-Bird Specific, not the GM A-Body car units although those are supposed to work), length adjusted based on pinion angle but close to stock T-Bird dimension
Four or Five Lug - Five lug conversion using stock Fox Mustang length Moser axles with five lug pattern (used North Race Car brake adapters for the rear SN95 brakes)
Rims - 17x9 Bullitt Style Chrome Replicas, 24mm offset with a 6.5" backspacing (I will measure this as I am not 100% sure but this may take a couple of weeks to get to)
Tires - Yokohama 275/40/17 AVS ES100 (no longer made)

1987 Thunderbird lx 5.0 stock.

stock axle/shafts/brakes.
Mustang 10 holes.
275/60/r15 fit nice, ocassional rub on driveways. full suspension travel will rub.

1986 cougar gs 5.0
Stock axle/brakes/rear
mustang 10 holes.
275/60/r15.




Tires fit well with no rubbing with no weight in trunk. 200-300lbs gives an ocassional scrub. had to zip tie e-brake cables. speedo is off about 10%
in the future i would go with 275/50's in the future.

I honestly dont think you could exceed the cost of a new car buy installing new *stock* parts everywhere in your coug our tbird. Its just plain impossible. You could revamp the entire drivetrain/engine/suspenstion and still come out ahead.
