Currently, I have Tein S-techs and Tokico D-Spec shocks on my coupe. I've been looking to switch out the S-tech springs with the Eibach pro kit Springs. The S-techs are sagging a bit and the rear is a bit soft for my liking. Also, I'm starting to think its been causing the noise I've been experiencing lately in the rear suspension.

As I was shopping around for the Eibachs, I started looking into coilovers . The HKS RS set seems to be well liked on this board as well as my350z.com.

I'm looking to drop my car 1" all around, a stiffer feel yet a decent comfort level when riding on the streets. I don't track or plan on tracking my car. It is a daily driver.

Currently, I have 19" inch Volks w/ the tire sizes almost everyone has, Stillen sways, rear camber arms, and a set of SPC front camber A-arms on order.

Which would you go with?

 

Do you have the 350Z S-Techs?

 

nope, the set for the G35

 

The spring rates for the G S-Techs are quite a bit softer than the OEM set-up . . . Well, for the '05+ anyhow.

I am sort of in the same situation that you are. I don't know whether to finish off the 350Z H-Tech springs with Dspec 9's, go with the Eibach ProKit plus the Dspecs, or simply go with a set of coilovers. My G is a daily driver, as well.

 

I'm selling my Prokit/D-Spec combo (with rear extensions) within this month when I get it off my car. It's a comfortable setup. I've had it for about 7K miles. The stance is perfect and performance is okay for the occasional spirited drive.

I want some something much stiffer and track applicable. I'm actually looking into the HKS RS or the Tein Flex JDM Version. Most likely it will be the HKS RS since the second one I mentioned will be hard to get.
