hi. i own an 04 g35c. suspension is currently stock, however...

i already have stillen swaybars and polyurethane bushings.
i have not installed them though.

where i live the roads are rough. i like how larger bumps are delt with (comfortably), but sometimes my suspension bounces on small irregularities and feels somewhat unsettled at speed.

having said that, im looking for a coilover setup (or spring/shock) that:
-is more refined (feeling more planted and connected to the road)
-supports the car better through turns
-wont feel punishing in an environment with rough roads
-can survive an environment with rough roads
-can be adjusted later on if i get aftermarket wheels and want to fill the gap

another thing ive noticed about my suspension is that on some high speed bumps taken at 60-80mph, the car bottoms out why is this?

The HKS Hipermax RS coilovers are at the top of my list right now. they seem like a good choice, esp for the money. I've read good things about Zeal too but its more money and ill never be tracking my car as there is no track here. also, i wont be able to corner balance the car as there are no facilities where i am for it. So all in all im not sure if the Zeals would be worth it? Anyway any suggestions/advice for me on the HKS RS or Zeals or any others given my situation would be appreciated...

 

any thoughts on Zeal vs HKS RS?

does it make sense to get Zeal over HKS RS if I cannot corner balance?

 

the requirements you gave dont match up...
because if you want great handling and feel connection to the road (like if you went over a coin and you can tell if its heads or tails) then the suspension has to be STIFF.

if it is stiff then of course it will not be comfortable... i'd think Zeal and HKS RS are along the same lines of JIC FLTA2's that I have, and to that extent it is something that you want to play slalom with the potholes and not drive over them because it will jam your spine, even at the softest settings...

so what im saying is if the roads are terrible, and you want to have a great ride, stay stock, or get less competition oriented coilovers/suspension set up

if you want great handling, compromise!

OR...
CHECK OUT THE NEW KONI FSD SHOCKS! (i just read it from european car mag...)
www.koni-fsd.com

 

actually jic coils i/m/o have been stiffer than need be.. Primary reason due to them being more geared towards track use.

Now zeal's are in my mind a double duty coilover. I've used zeals for daily and they don't punish the driver. Yet with just coils without sways i have no problems at the track. Just something to look into. Remember just because the coil is for track doesnt mean it can't be somewhat street.

 

yeah i agree i think if he has a G, he probably want something that would keep the luxury ride quality.
the new KONI FSD is designed for drivers that want some sportiness and still keep the ride quality.
(i never tried it but after reading the European car mag review for it, thats what my personal interpretation is)
... maybe he can try the FSD and tell us how it rides

 

For your uses, I'd take a hard look at the Nismo S-Tune setup. It's a great sport system that IMO would suit you better than most of the aftermarket coilover setups I've experienced. It's not particularly harsh, yet tightens up the ride substantially. It also eliminates a good deal of understeer when mated to the swaybars. It's also more cost effective, and is a 'set it, forget it' system. Shock travel remains excellent for bumps, etc.

 

thanks for the suggestions.
i dont want to try something without having read any review, so im sorry but i dont think i cant try the new konis

as far as the G goes, i cant see it as a luxury car, and in some cases has the same suspension as the Z so... im not looking for more of that.

im starting to think that this is something that just has to be felt. unfortunately (or fortunately) ive yet to read a negative review of the Nismo S-Tunes, HKS RS, or Function XS. All reviews have been glowing. I'm starting to think I cant go wrong as long as I'm willing to accept some morestiffness and am comfortable spending the money.

JRitt, do you know how the Nismos compare to the Zeal Function XSs?
Also, with the Nismos, the ride height is not adjustible, correct? I'm forced to take a drop?

 

Tekk,
I unfortunately don't have any experience with the Zeal's.

With the Nismo's, height is NOT adjustable. That said, the drop is very minor...probably 3/4 of an inch. It's a nice setup, and you retain a good amount of shock travel. The ride is a little more firm than stock, but ride quality actually improves IMO, and the car handles much better.

 

only problem i had with nismo suspension was non-adj and cost almost as much as the JICs...
for 1600 dollars you'd definately find better suspension than the S-tunes
