If you have factory suspension you have no adjustment and no way to gain. I think my stock alignment was around -1.0.

To All: If you follow the link above to watch Tom driving, you should also see a video listed in the column to the right: "370Z at Goodwood Hill climb" or similar. They get to drive quite a long way. I'm wondering if such events are open to all and, if so, how we could organize similar events in the states.

The Goodwood Festival of Speed is a huge event, but there are much smaller hillclimb events here in the US. There are at least a couple in the North East where I'm at, so check around.

Lots of hillclimbs in the North West US. And they are much longer. Here is a video of me at my first ever hillclimb a few years ago. I was very careful. I went faster in a slower car the next year but my videos didnt turn out well.

I'm planning to bring my new Nismo Z to hillclimb this year. Other than crappy LSD the car should do OK as Hillclimbs usually reward power.

The understeer is why I wanted to stay away from replacing just the front bar to get rid of the inner rear lift. I understand it is faster, but I just hate to have a car that drives $hitty. My car isn't an autox only car, so it has to drive nice at the track too. I guess a smaller bar would be a good compromise.

Autox Z, what bar did you use on your car?

I believe Hotchikas is 35mm, Cusco is 28mm, Whiteline is 32mm (2 pt adjustment), Nismo 27mm, stock 26mm. Stillen is 32mm I think.

I wanted to give Sam Strano and Salvatore Dipompo congratulations for taking 1st and 2nd , respectively, in C Stock at the Washington D.C. Region SCCA, Inc. WDCR Solo Championship Event #7 Autocross/Solo II on Sunday.

Also, for Learic Cramer in blowing the doors off the ladies and the men (she actually ran faster than Salvatore Dipompo).

All three were co-driving a yellow 370Z.

I was pleased in taking 6th place (out of 10) in C Stock on my RE-11’s at my first SCCA event.

Sorry I just saw this post. I use the hotchkis bar and it's just about perfect with the Hoosiers on the car. However on street tires the understeer was well, epic. I would recommend a smaller bar for street tire use.

I got .8 one side 1.3 the other

we were back at a "norma;" autocross layout today... i felt just like you guys... i have new tires up front and about 3/32nds left on the rear and the car oversteered pretty crazy today felt just like driving a Z... will take that over the normal understeer all day

Cool, thanks for the info

the rules change every year, make sure you don't need a cage to do this.

I'm excited about the potential bump for the 350z's to ESP!

I need some advice. I just started running in the street tire CS class my local SCCA has. I want to upgrade to some better tires, and hopefully get rid of the understeer. The car is 100% stock. What size/type of tires do you guys recommend? It seems like RE-11's are the best option. I'm hoping to reduce understeer by reducing the difference in front/rear width. Am I better off running 275/30 front & 285/35 rear or 285/35 all around? It seems like 285's are a bit of a stretch on 9" wheels in front, but the 275/30's are 1.2" smaller diameter than stock.

Also, what would you recommend for alignment settings on a stock Z? I know were pretty much screwed for camber, but has anyone tried playing around with the other settings?

cossie1600 · 04-23-2011, 08:32 PM

285/35/19 all around works. I only have one event under the belt with the new setup, but I can already tell the plow is less noticeable than before. There is a stretch, but you will live.
