I wouldn't do it for a performance suspension. It works alright for driving around town type of suspension, but it's too low on stock style dampers for outright performance due to the extreme reduction in bump travel. Even with shorter bump stops it still sits on them all the time. I have to run my Konis almost all the way stiff to keep up with the normal around town forces I experience with them.
If you are serious about wanting to do track or autox driving I would save up for some decent coilovers.
