http://www.rs25.com/forums/showthread.php?t=62822 The prices are rediculously low. A step above megan racing for not much more.
I have installed a few Ksports (off the shelf versions) on many EVOs....they are pretty nice. However, for the price, you cannot beat the Megans.
Be careful with the ksports, they are very much like the "jiggle in your cars (JIC)". They will rattle the hell out of you on the highway when there are those little divider bumps, speaking from a friend who owns a turbo'ed protege. What is the total price of the ksports on that site? I only saw the $100 deposit.
So the dampening was really good? I may consider these if thats the case. I am always afraid of the school bus feeling on my daily driver.
The price for most of the kits are $999. Not sure if that includes shipping or not. The GT kit is $1150. The great thing is the custom valving and spring rates on the RR kit. Although I was looking at the AR Rally kit because of the extended stroke and reinforced shock. I've ridden on Megan's (which have a short stroke) and the KW3's (which have a longer stroke) and the KW3's just felt more comfortable as far as daily driving goes. But they were a lot more expensive than what I paid for the Megan's. I figure this would be a good median.
The ride was significantly better than stock. It was a lot firmer with little to no oscillations and no rattles. However, this was all on street driving. I never got in his car at the one autoX he did.
