Any one use the HKS Hipermax RS coilovers on a sedan yet? If so, what are your impressions? Thanks.

 

I'm running the LS on my sedan and I love it. I've heard very good things about the RS. There are some coupe guys that have it, maybe a sedan or two.

 

If their's a sedan that has the HKS RS coilover's on, they haven't posted about it, least not that I've ever seen. It's what I'd have on my car right now if I had my way. I'll likely have to go a different, less costly route instead however.

 

HKS RS (Monotube construction, adjustable dampning)
Spring rates 448/448
Stiffer then oem by F+43% R+31%
Transfers 12% roll stiffness to the front
Special Note: “Marketed” as HKS’s track coil over with a good street ride.

HKS LS G35 (Monotube construction, non adjustable dampners)
Spring rates 448/336
Stiffer then oem by F+43% R -1%
transfers 44% roll stiffness to the front
Special Note: A comfort ride system, compare to Tein CS coilover

HKS LS+ G35 Coupe (Monotube construction, adjustable dampners)
Spring rates 504/448
Stiffer then oem by F+58% R+29% (rear springs are progressive)
transfers 29% roll stiffness to the front
Side Note: Has the unusual distiction of actually being valved stiffer then the same coilover made for the 350Z, though the Z version does NOT transfer as much roll stiffness to the front

HKS II (Monotube construction, adjustable dampners)
Spring rates 504/504
Spring rates F+61% R+47%
transfers 14% roll stiffness to the front
Special Note: sprung and valved to be HKS’s most aggressive product, it is a notch above the RS coil over on the track, compare to Tein Flex and Jic coilovers

 

Gsedan35, thanks for the info. I too would like to have the RS on my sedan, but I don't think I will get that past the boss(wife). What suggestions do you have for a less costly coilover system? Thanks again. Take care.

 

Gsedan35, I can't find the post where you detailed the total cost of lowering a G. You included things such as camber correction parts that are necessary and some additional labor. Could you please either direct me to that post or re-list the necessities for properly lowering a G sedan and getting it back to factory alignment specs? I appreciate any help you can provide.

Also, is it better to transfer less roll stiffness to the front? Take care.

 

Transferring roll stifness to the front will induce more understeer during cornering. That's why the track ready coilovers such as the RS and II have even spring rates up front and back for a more neutral setup. The comfort system LS and LS+ have more roll stiffness in the front because it is much safer to have understeer for the street setup. It is much easier for an average driver to correct for understeer than oversteer. Most cars from the factory come tuned in an understeer state for safety reasons.

 

Hmm, trying to rember what post I made, Was it that mass catalog of sorts, where I listed all the known alignment correction part's I could think of? I can only guess, rather poorly at that what install cost's would be, since I do all my install work myself. Front correction is still kind of a tuff thing. Cusco looked like a nice cost effective way to get it done, then the bomb shell that it could offer a max of .5 degree's of correction. Which, depending on your drop amount, may or may not be enough correction. The Kinetix kit is the same price and does offer more correction, but you'll have to be your own judge on how you feel about it. The 350EVO arms remain the best IMO, sperical bushings and plenty of adjustment range, but expensive. The rear is easier, SPC camber arm's and elongated toe bolts.

Hope that helps.

 

skeleton_cru,

Did you have to correct your camber after installing the LS coilovers? If so, what parts did you use? How much did you lower your G and what size wheels, offset, and tires are you using? Thanks for the info.

Take care,
Allan

how does the Tein Basic compare to the Hipermax LS

 

The Tein Basic is more of a budget performance coilover while the HKS LS is more of a comfort, luxury system.

 

Anyone with a sedan install the HKS RS coilovers yet? How about coupe owners? Thanks.
