It's a Scootworks lowering kit. I bought it used from Vindiana Jones(Thanks again Vindiana!). I didn't lower the front. I had it installed by the local dealer who charged $129.00. I would have done it myself but I didn't have the larger sockets or the jack, so by the time I bought those things I would have been close to the dealer cost for installation.
I really like the low, stretched look of the Custom. Lowering it seems to have added to the theme. If anyone has ideas on how to expand on that theme I'd love to hear them!
