I hope that I am dealing with the final issue on my “towcar in-training”. After three weeks of struggling to find a set of wheels that are straight enough to roll down the road without vibrating the vehicle apart, I finally found a dealer with five NOS American Racing mag wheels with a weight rating of 3,600 pounds each with the proper off-set for the Cadillac. The problem with the new wheels is that tire clearance is reduced to less than 2” in the rear, and with the soft suspension (the car has heavy duty Cargo Coil springs that were new last year) my tire dealer is afraid that a pothole might cause the lip of the fender to contact the sidewall of the tire (deflection would have to be about 2.25”).

The solution that is being considered is to install either AirLift 1000 air bags inside the rear coil springs (a kit is available from AirLift for this application), Firestone Ride-Rite air springs (a kit is not available so a weld-up custom install would be necessary), or ShockWave 9000 (Shock combined with Firestone Air Spring) <this would require cross-referencing the car’s original shocks to the new units and comparing manufacturer’s specifications to available clearances>. Does anyone on the list have experience with any of these products?

I am satisfied with the towing performance of the car with the current heavy duty Cargo Coils and heavy duty air shocks with my Reese Dual Cam hitch setup. The goal of this modification is to maintain the ride height at the most consistent level possible to avoid having contact between the rear tire sidewalls and the inner lip of the fender.

Any input will be welcome!

Thanks!
