I got mine for about $200 off during the winter holiday sales a few months back. That was the cheapest I had seem them. Down time will be a drag, but definitely worth it considering their performance and it will be a lot cheaper than buying a new set of PSS10 shocks or similar setup when performance starts to drop.
According to Barry from 3DM, I guess the MT21 and MT22 is being discontinued and replaced by a version with shortened shocks and struts to allow for more lowering. I guess the Audi MQB owners shopping the same kit didn't like the lack of lowering since those cars start lower than ours from the get go. I think I got one of the last kits that allowed the car to stay closer to oem ride height.
Dang, I actually want to stay closer to OEM height. Hopefully they're adjustable enough I can get back up to less than an inch of drop. Or they find some sets kicking around and put them on clearance.
