Hotchkis springs questions..
I'm thinking of getting Hotckis front and rear sways and possibly springs, but before I do, I need to know a few things.
First, will there be too much negative camber (it would be negative, correct?) by only getting Hotchkis springs?
Second, I keep reading something about how Hotchkis springs are actually less stiff than OEM, is this true? If it is, how is the handling improved?
And thirdly, do the springs actually make a significant difference in handling?
Thanks

I have the Hotchkis sways and springs and they made a HUGE difference in handling. I installed the sways first and that made a large difference, but the springs eliminated all of the remaining body roll with the car. I highly recommend installing both cause together they make the biggest difference.
The springs are stiffer than stock, but it's not very noticeable for day-to-day driving. When I first autocrossed my Z was when I really felt the major difference with the springs.

Oem springs 350Z’s 2003/2004
Front:314 Rear:342
Oem springs 350Z 2004.5 to 2006
{EDIT} Forgot to actually post the rates,....SORRY
314/427
Hotchkis 350Z Linear springs .6”/.8” drop on 350Z
Spring rates in lbs 340/330
Stiffer or softer then oem springs by F+8% R-3% (vs 2003-2004)
Cut and paste repost of email from Hotchkis responding to criticism of softer rear spring rates (writer is of course refering to a car equipped with the unrefined 03/04 shocks/suspension)
Here is an email I got from John Whatley of Hotchkis:
quote:
There is no error on the spring ratings. The rear spring is in fact softer than the stock. The reasoning behind this is that: during testing we found that the rear end likes to bounce under hard cornering. By reducing the spring rate in the rear we were able to get more MPH in slalom testing and stopped the bouncing that occurred. These springs in conjunction with our swaybars will be matched with each other to provide a neutral feel under hard cornering.

as commented in another thread, we've been using the Hotchkis alot on the 06's and it's worked out wonderfully - zero issues and the car looks, handles and rides very well

06 spring rates
Anyone know the 06 spring rates? Hotchkis sounds like a good setup. I have posted many times that I thought the rear springs are too stiff and that the rear of the car bounces too much (and as a result, unweights the rear tires, which is not good!)
What shocks to people use with Hotchkis springs and sways? I have been partial to Koni yellows (SA) on the old M3.
Also, the 06 OEM front sway bar looks HUGE. Are after-market sways that much different? how so? I don't notice too much body roll on my 06 GT...
Thanks...

06 springs rates have been posted in this thread!
We recently dia roadster (06) with stock tires and did the Hotchkis springs and sways- ride quality was unaffected by the springs (I drove the car before and after down the local roads at the shop), it just sat a bit lower. All in all, an awesome set of springs.
They are designed for stock shocks or a relatively mild shock upgrade. I personally would not use them with the Koni, as that shock needs a very stiff spring to be effective.
As for sways, the stock front is on the larger side, but a larger one does wonders for turn in response and reduction in body roll. Hotchkis and Cusco sways have worked out very well for us

The back of my car seems way more stiff than my wife's enthusiast. Stock for stock.
I am leaning towards the Hotchkis stage-1, but still like the idea of the dealer-installed and dealer warrantied Nismo s-tune, but that's money...
decisions...

Well, how useful is a warranty on suspension parts?
Good springs will outlive the car. Shocks are at most $600 + installation to replace. Sways also will outlive the car. End links, not very expensive to replace either.
I don't think it's worth paying up extra cash for nismo suspension if your only concern is warranty.

How much should it cost to get sways and springs installed? My local guy said 100 for sways but 400 for springs.. $400?? Sounds way too high to me, but he said its cause they need to disassemble the whole spring/shock system and all that stuff..

Yeah, The end-lings on the e36M3 are definitely considered wear items.
Do you have the sways? I know they are good for the corners, but do the detract at all from the independent-suspension feel?
Sure would like to hear from on 06 GT owner that went to Hotchkis stage-1

sways do not detract from anything...they make the car handle even better than it does stock, and turn in far quicker than stock
install for springs is a 1.5 hour job - sways adds another .5-.75 hours total. All told it should cost around $150-$175 ish

So what (if any) is the history of Nissan's spring/shock changes since the 2003 model? I know there have been some alterations.

So I am tuning it for the street, where there's bumps.
