KW Variant 3?

Scott@FontanaNissan

I've done development and testing with KW on several cars in the past. The KW's are simply proven and effective. Parts for them can be purchased easily and if they needed to be re-built, it can be done right here in the USofA!

I've run the KW's on my Time Attack car for the last 3 years. They are more comfortable on the street than stock, and extremely stable at high speeds and varying surfaces.

I'd be happy to help anyone get a set as we are KW dealers here!

i dont understand how a suspension can be more comfortable than the other, and still provide superior handling. usually to get a good handling car, the suspension needs to be stiffer than stock to provide that improved handling, therefore sacrificing ride quality. it almost seems impossible to me to get a softer feeling suspension to handle better than the other.

It uses a progressive spring that is initially compliant for a decent ride then as you put increasing pressure on it, it starts to stiffen up more.

intresting. so overall the handling capabilities of the kw's are better than the stock suspension?

dszombiex

Way better. The largest difference I noticed was in multiple turns. It does a great job of suppressing body roll tendency compared to stock. Or it just seems to produce less lateral force in turning. Kinda had to describe.

do you still retain the double wishbone suspension up front with the kw coilovers?

LOU@AMPLIFIED

. They are basically the same set up as the OE. Just added better shocks with dampening adjustment capabilities and progressive springs with adjustable purch for height adjustability.

I know the OE 370z suspension is already great out of the box, but impovement on top notch suspension upgrades like KW, JIC etc.. only improves the suspension for better handling without sacrificing daily driving comfort.

Dean, have your KW'S settled? when are you coming in for your free height adjustment

I am under the impression w/ springs you need to get a camber kit but w/ coilovers you don't.. am i off in never never land or is that the general consensus?

Modshack

The need for a camber kit is determined by the amount of drop...Most springs and Coilovers start at least 1" lower so a kit will most likely be needed with either..

Not the case on this car - once you lower the car, sometimes even as little as 1/2 inch, at least an aftermarket rear camber/toe kit is required to bring things back to spec. Up front, the car can deal with, and actually likes, a bit more negative camber. I have not yet seen a proper front a arm set for these cars, but there will be some good, solid options available soon. For the rear, there are several good kits available

Robispec

it's a $$$ issue....you can get the best of both worlds...it just costs more..

yo u mentioned that the robispec 370z is running kw v3 with straight rate springs. so just to clarify that means you got rid of the progressive spring rate? what did u end up having set the compression and rebound of ur kw's at?

tooohip

What ever happened to the American Education system anyway...

Sigh...

dont understand whats with the haterade but i guess during ur time the "American Education" system was teaching you how to use smileys to convey expression and the need to use formal writing skills in a colloquial environment...

Robispec

I kept the compression as dynoed in the middle (one turn) from full stiff the rebound I added a .25 turn to the stock settings....front and rear. This is giving a Smooooth ride and the car is so low that we aren't having any wallowing issues...

Just as an aside, the 370z chassis is not designed for the coil spring to load the SHOCK tower.... and in the interest of giving some usable room under the hatch they have also removed the reinforcement found in the 350.....the Aluminum tube is for side impact only...and putting a coilover on the rear also kills one inch of tire/wheel clearance (12" is a bit much I guess) But the boosted boys will need all the room they can find...lol. Soooo until the Robispec 370 is caged..and we reinforce the shock tower to take the loads, I will keep the stock spring location....(it doesn't look like the 370 will coil bind out like the 350 did...) so it looks safe.
