Understeer

ChrisSlicks

I've tried many staggered tire combinations on this car.

245/275 stock
275/305 RE-11
275/315 NT-01
315/345 V710 - For the extreme guys

On all the setups I've dialed the car in to feel pretty balanced, but front tire wear is twice that of the rear. I'm considering a square setup next to see how that goes for front tire wear.

As far as understeer goes on track it can often be driver induced, such as trying to combine too much turning and acceleration. With Auto-X it's inevitable, you just have to manage it.

I'd have to say with my Nismo it's rare case that I experience understeer in AX. On track never.

Maybe it's because I come from mid engine cars but honestly I rarely understeer with Z in AX. But I'm a consummate late apexer and have no fear of using power oversteer to rotate the car if needed.

But then I'm putting down a 295 Hoosier up front. When I go to 275 front and 285 rear street the car is an oversteering monster! But its very controlable oversteer. I just drift entire ax when I drive streets! Lol!

With the stock suspension and stock stagger, I don't think you can drive anything sideway unless you are stuck in the snow

ChrisSlicks

At auto-x the car will only rotate under power if you have 2 things, enough front grip, and enough power to break traction at the rear. At higher speed auto-x is can be harder to break the rear-end free under acceleration especially when I run the 345's in the summer and they're nice and sticky

WOW 345's ChrisSlicks?! That's man's setup right there LOL!

AutoX Z

With 295 A6s on the front, even pinched on stock wheels, you can make the car oversteer by tweaking shocks and tire pressures. It's never going to rotate like I would want it if I could change springs or bars but I wouldn't say it understeers.

Agreed and just think what you could do with some real negative camber and toe out up front. My car pretty much goes where I point it even if I do stupid stuff. People are amazed by my car in that respect so I have never understood anyone with some level of mods indicating these cars push. Never experienced it and with 315 Hoosiers I rarely find so much grip I can't goose it out of a slower turn but that's so rare it rarely happens to me.

The one thing the Z has as an advantage over EVOs and Porsches is it ability to turn like crazy. My issue is more with being able to put down my 450 hp lol! I leave two big strips of rubber out of slower sweepers.

I love the turn in speed with my square setup and your right Chris I'm running -3 up front and rarely find a push understeer unless I'm coming in too hot.

ChrisSlicks

The car does turn hard once modified. With -3.5 up front it is extremely nimble in the slow stuff. Like I said I only get push in the higher speed 55-70mph maneuvers with too much rear tire. I'd really be better off with a square setup for auto-x.

You guys are lucky. With the street tires and my pathetic .9 degrees, I have to wait before i can turn. The slower it is, the harder it plows

///MSH

With 275F and 315R, I can induce oversteer just by lifting a bit just before I hit the apex allowing me to throttle-out. Bare in mind I am AutoXing on A6's. As a point of reference, my next set will be 295F/315R A6's!!! I do run approximately 2-2.5 deg neg camber up front with stock ride height and 18's. Good luck!

Which front camber arms are you guys using? I've been holding off since I've heard mixed reviews about most options out there. My car desperately needs some negative camber up front...my tire shoulders can attest to that.

SPC right now, I'll upgrade to the Doran's or the SPL's when available. The SPC's get the job done, but if you do a lot of curb hopping or harsh tracks then they can slip out of adjustment. They are strong, but heavy steel, adds about 4 pounds each I'd guess. The ball joints in them lasted about 18 months, but at least the replacements weren't that expensive to replace.
