Auto Solutions SSK is 100% doable on jack stands, a lift is definitely not required. The hardest part for most people is removal of the shift arm because of it's awkward shape and lack of room, but if you have someone else with you, and can drop the transmission down a little bit, you'll be golden. After you get past this obstacle, the removal/install is very straight forward. Ron will remind you numerous times in his instructions (with big warnings and pictures) to make sure you have the shift lever installed correctly, as it's common for people to install it backwards. Time taken for the install depends on how mechanically inclined you are. There are plenty of videos on youtube to guide you if you need them. After doing two installs myself, I'm confident I could knock it out in 2-3 hours. A first timer who is unfamiliar though, could easily double those times.
If you're doing this install, I
HIGHLY recommend swapping out your OEM rear shifter arm bushing with Turner Motorsports polyurethane upgrade. It only cost about $40 and it completes the kit by eliminating all of the OEM rubber bushings & their potential to be a weak link in the chain. There's literally no reason to not do it.

My car is equipped with Ron's SSK at 28% reduction with a ZHP knob, no additional height, and I have zero regrets. I actually have no intention of upgrading to CAE, even as I begin to shift my focus from HPDE's to time attack. This shifter gets the job done, and as the saying goes.... if it ain't broke, don't fix it. Ron is a wealth of knowledge and just talking to him for 5 mins, you'll be blown away by his experience and wisdom when it comes to BMW shifting assemblies and mechanisms.
