Your doors are too heavy to have lamborghini mods. If you do it, the hydraulic lifts will wear out quick and you'll find yourself replacing them all the time. It happened on a Ford MUstang and the lexus doors are way heavier than mustang doors.
Yeah, I knew they were heavy; I was afraid of something like that.
Problems, you think, even if the company selling the kit says it could handle it?
If i was the company selling the kit, i'd sell it to you regardless of any known problems and make money on all the hydraulic shocks i'd be replacing for you over the years. Only get it if they warranty the shocks for at least a year or two.
