My car sets low enought about 3 " of downward motion would scrape the skirts. And my Air shocks still had enough travel so that I put a ext. on the lower shaft { The extender was made back in the late 50's for 52-54 fords that were lowered to remove the rear tire }The rear tires on my car come off good. I have stock wheels with 195X14 radial tires.
Hope the speedo gear does what you want and yes I got the cash.
