and the number is.....?

Crazy expensive. lol
MSRP for the HLS 2 Kit: $3545
MSRP on the HLS 4 Kit: $4669
And don't forget, you gotta shell out the skratch on the coil overs themselves.

Just get a full air ride suspension kit. Seems this is almost what it basically is. It would run about $2500 to $3000 and be done with it.

The HLS system can be adapted for use with other coilovers with minor modification to the perches.

Update/old bump on this thread, KW does NOT manufacture a kit specific for the 370z due to the car having progressive springs. They also will not warrant or guarantee anything if using springs that are not their own (ex SWIFT linear)
