OK...I was confuscious but not anymore thanks! At any rate I will need to get coilovers eventually. I may just forget about getting shocks and save up for the KW3's or maybe something better.

The Z will eventually be an occasional street car and not a daily like it is now.

We aren't allowed sphericals.
:(
I believe min ride height is 3"
One of the things we played with at Barber this past weekend was front ride height.... Running some quick in and outs after baselining the car/setup.
I can say this... For our particular setup there is a "sweet spot" on ride height. When we even went 1 complete turn up on the front springs ... It brought on an understeer.
Barber is a tough track... but a great one to try stuff on... even on old tires.
;)

It is really a function of varying roll centre I'd have thought ... as changing ride-height will vary the roll-centre - do you agree ??.

Interesting that it is so sensitive though - I would have thought that chassis stiffness as not high enough (unless your cage feeds the front suspension pick-up loads back into the rest of the bodyshell/cage). Maybe Mr Nissan's claims about chassis stiffness are being borne out here.

Let me know what you think...

Agreed on the roll centre.
But also I think it is a combination of a lot of things that make everything work.

Front to back rake will make a big difference in aerodynamics both above and below the car. But that's not what this thread is about.

I saw Heitkotter's photos of your arms. So pretty. Sell them. Sell them NOW.

Rake is good to have some...but aero on our car with Hoosier/Conti Competition DOTs doesn't make a huuuuuge difference... It I what it is.
Changes to rear ride height effect the rear from center of the corner out.

I checked google translator and it doesn't understand you all either :rofl2:

the arms are amazing looking and feather light. saw them at z nat's. cant wait to get a set!

Front Ride height is going to adjust a number of things. Roll center being one of them as well as Camber, Caster, Toe and weight distribution. 1 turn on an AST coilover is 2mm but you also have to account for were they mount into the lower control arm so likely about 4-6mm in actual ride height change. The weight transfer from that could be as great as 100lbs front to rear but I have not that experienced with the 370z in particular. I do know this much though I am sure the car is stiff because I know how Kevin Doran designs his cars. They are usually some of the best designed cars in the paddock for a number of reasons. I mean after all this is why teams try to steal his designs (cough, Insight Racing) I also know that B.J. isn't just one of the best drivers on this forum but also in the paddock (if not the best). He has an ability to feel changes in the car that would go unnoticed by us mortals but also to other drivers in the paddock. I got a chance to look at these arms in person and they are extremely impressive. I thought the design was on par if not better then the arms that are on the Doran Ford GT-R a car that finished 3rd at LeMans with a Husband and Wife team! As always extremely impressive stuff from the Doran Stable!

QFT! Those things are gorgeous. So are the rear camber/toe arms I saw on the table.

I told them they had better not turn their back or stuff might start magically "migrating" onto my car...

I'm hoping that once they dicide to sell them. We can get them. Going through Nissan Motorsports sucks at times. :(

Updates?

:eekdance::eekdance::eekdance:

Well kind of.
We have driven down to Canton , Mississippi and displaying the 370z RC at the Nissan facility tomorrow .
On the way down we had lots of time to discuss the sale of arms and our sway bars.
The only issue right now is the hardware we use on our race front control arms is very high spec and quality .... And limited quantity.
Looking for some options to offer more of a club sport using different hardware from another source.
The arms are finished ... Just trying to make them available for a little less.
