We offer 1" & 2" lowering springs designed with a 2-door coupe/SBC in mind. Many customers call and ask for specific ground-to-fender measurements in mind.
Unfortunately, we cannot 100% predict a fender-to-ground or more impossible tire-to-fender measurement because there are literally dozens of different results for any given spring on a GM-A body. The reason why is due these variables:
· Make: Chevy, B.O.P. (wheel-well shapes vary)
· Body Type: Coupe, Sedan, Wagon, Utility Truck
· Engine: 6 cylinder, V8 in various GM brands
· Options: AC, Power Steering, Power Brakes
· Spindles: Stock spindles or drop spindles
· Wheel/Tire sizes: 14"-20" & the corresponding aspect ratios
· Body Bushings: If the body mount bushing are old (compressed) or new
All of these variables will actually determine the eventual ride height of a GM A-Body. I hate to tell customers that it is a guessing game, but with all of the variables mentioned it can be.
I always suggest to guy that are after a very specific stance to go with Viking or QA1 coilovers. Not only can you dial in your ride height(stance), you can dial in the shock for what it is that you are doing with the car that day, that weekend or for good.
