It's too soft for track setup but it also is really the dampening that needs to be fix. If I had the money, I would buy MCS from Wyatt here. He works at MCS and made me jealous of his 3-way MCS dampeners.
derek, are you running off-the-shelf yellows or are they GC 'spec' (i am suspect about this)?
you should try the BW RTABs and some form of stiffer diff mounts. you'd be amazed at the power transfer.

Thanks for all the super helpful responses, guys!
I'm definitely leaning toward PSS10 or KW V2.
Am I correct in saying the PSS10 has both rebound and compression adjustment, but they are not independent, where the KW V2 only has rebound adjustment?
Are there any suppliers who offer a spring replacement to Swift or other brands, or would these need to be purchased separately?
Just be warned on the design of the KWs. The little hex key screws that hold the adjustment rings in place can get gradue in them and bind. I bought a used set (v1?) and could not get them loose-after trying everything we could think of. Perhaps ones with two rings that keep each other in check is a better design.
Why do you need to replace the springs? Normally if you do, you would want to replace whatever springs with Swift or Hyperco.
Look into Fortune Auto coilovers.

All you have to do on the KW to keep the hex key from seizing is, before installing, take it out, put a little anti-seize compound on it and reassemble. Simple solution
