That is odd to hear, I've only heard great things about the KW. I recently got my 08 ISF and I was shocked at how bad the ride was, especially on imperfections(and in Baltimore there are many). I upgraded to BC Racing coilovers with soft swift spring upgrade of 14/10, then I went to 20/25 from full stiff, so it is rather soft. It now makes for a great DD and is much more comfortable. I will say it may be soft for some, but once we get past winter and into some sporty driving days I can firm it up quite easily. Here is my height with 19" wheels with 35/30 sidewalls.
Perhaps you may need some dampening adjustment or a softer spring setup? I went with 14/10 but I know some like it firmer at 16/12 or even 18/12.

I've got the BCs 14/10s going on Wednesday. Do you know how much drop your running front rear? And does it bottom out on those soft settings?

I was having similar issues with the front end vibration when going anything over 55 mph. when i installed my BC coils 18k/14k the road feel got substantially better and going over bumps was much smoother. Mike from Figs suggested this spring rate for me and i don't regret it one bit. my Issue with the front vibration was due to unbalanced high speed tire rotation and needed front alignment. Now with a big unmatched tire sizes that can also play a big roll in feel as well. might want to consider going a bit wider up front to match the new rear tires. i've seen guys in the ISF aggressive fitment thread run 245 front with 285 or 295 rears. Just contributing to finding and resolving your issue. guys on this Site have some great insight on info. won't hurt to start doing a process of elimination to find your solution.

thanks for the replies everyone. I have Vorsteiner Wheels, not sure of the sizes or offsets as I bought the car with then and I didn't see any wheels specs inside the wheels, but i'll check again today. taking the car to get the coils readjusted and lowering the front to the next setting, then going to get an alignment at 714 tires in Westminster(OC) and have them rebalance the front tires, although I had a repair on the front passenger at America's tire last month for free, so I'm sure they are both balanced correctly, but I"ll just pay to rebalance them before the alignment.
