The thing is people often forget what coilovers were developed for....track use primary and adjustability. The reality is most people do neither. The cars are rarely tracked and fitted and never touched again. Equally, they really need to be set up properly which can cost about another £80-£100 alignment. With all respect, most people (including myself) are not good enough drivers to exploit the expensive coilovers. If they are honest, most just want the ability to lower it as much as they want which can upset the handling anyway.
Personally, I'll wait till someones parting out some KW's on the forum as very few cars are a keeper and someone will look to want to recoup their initial expense. If you pay the right price for them, you can sell them for around the same price 12 months later.
