Hey guys,

At my last AX event I chalked my tires and saw that my fronts were rolling over way too much. They were going past the triangle on the side of the dunlops. The back tires when set to 35psi were spot on where they should be. Does this mean I need front camber arms or do I need to change my suspension setup? I inflated the front tires to 43psi and still had the roll over.

My setup:

Dunlop Z2 19/275 front and rear
Eibach front sway full stiff
43psi fron and 35 psi rear.
0 toe front 1/8 toe-in rear and -1.5 camber rear

Yes, you need front camber....

Thats what I was afraid of. Think I can get away with jacking the front up past 45psi until I can get camber arms?

I ran 40psi in my RE-11's until said camber.

I am considering removing my rear sway bar for this sundays autox just to see if it helps any. I have 13k springs up front and 9k springs in the rear. I am also running bfg sport comp 2 tires and about 2 degrees of camber up front and 1.5 rear. Is this a good idea or should i just leave it alone?

Don't have to remove bar to try...just disconnect ine end link and see how you like it

Has anyone ran the adjustable Koni Sports "Yellows" for autox with good results? I see tirerack has 25% off until 5/31. Thanks.

What size wheels are you using, and with what offsets, spacers, etc?? How well do they fit on the front wheels?
TIA

Also, Koni Yellows are usually the go-to choice for stock class.... unless you want to spend a lot more on Ohlins or custom Koni's.

Out of curiosity what is everyone running in terms of aftermarket shocks and springs for autox? I have been reading up on powertrix, fortune auto and bc racing but I don't see anyone on the forums using these for autox.

Really? That's good to know. So I can autocross on disconnected rear sway and I have not have any problems... Should I at least zip tie it or something?

I used custom double Koni's in late 2010-2011, switched to Motons for 2012-2013 and now use custom Penske shocks...

Very nice. I looked up the motons for the 370z and they are 4k. Were your konis done by true choice?

Also have you run anything more midrange? Something better than the konis but less expensive than motons and penske? 2k is my limit.

chknhawk · 06-25-2014, 04:51 PM

I run stance gr+ true coils. In the process of getting some heavier springs. I have heard BC coils are one of the best for the money...
