I picked the 2"drop. I couldn’t imagine only 2" making a great deal of difference.
I am ordering a setup this weekend. $2600 for all and $1873 for just the front suspension kit. It consist of a Heidts Deluxe kit, and includes brake lines, rack extensions and front sway bar. I also asked the vendor to include the rear suspension, engine mounts and master cylinder mount. The rotors are 11 inches with a Ford bolt pattern, control arms are tubular, and rack is manual. Spindles are stock height. It was explained to me that the stock height spindles will drop the front end 3-4 inches and the 2 inch drop spindles will drop the front end 5-6 inches. IMHO, you will be in the weeds with drop spindles.
