Post your track setup

[waldowin]

1986 Nissan 300ZX w/ '84 Turbo 300ZX motor (sorry for the lack of E30 love, I'm working on it)

Tokico HP springs/shocks
Methanol Injection
"Test pipe" exhaust
K&N Filter (for the mad, mad HP boost, and extra dirt)
Yokohama AVS ES100 225/45/15 all around

Slight understeer if you enter a turn too hot, otherwise sticks like glue. Until the turbo spools, then the lack of Limited Slip Diff rears its ugly head and the rear of the car passes the front in a hurry if you're not ready for it (trailing arm suspension FTW!)

When Nissan built it, they really didn't have corner carving in mind, but the new suspension makes for -2.5* of camber in the front, and -1.5 in the rear, so it's not a total loss. Though tire wear at the track is a bit of a bitch.
High speeds = slight understeer, which is a bit handy for tackling esses, really.

stock m42, 'cept for a JC chip
IE stage 3 springs
Fresh bilstein sports
THR cabs
fresh front end parts

that's honestly about it. running a recaro shell and 6 pt harnesses, but other than that, nothing too fancy. 16x7 comps shod with 205/50/16 es100's.

setup is neutral. as my last autox instructor told me (some old guy that drives a JS e30m3, e36m3, blah blah), the car has plenty of grip, just no go. it's a fun car to toss around at a track or autox, and still drive home.

my setup sucks. the rear lets go before the front because i have no camber back there. and my ghetto solution of no rear bar is the weaksauce

i need to drop the rear an inch and rehook my bar back there. possibly throw down for an IE big front bar, then swap rear rates if need be.

My car became quite a bit more confidence-inspiring when I switched to 375 up front (back to 475 rear). I've had some scary snap oversteer situations with the old setup, it seems much more forgiving now.

Chris, the Hankooks are in 225/45/16. Get those.

And I'd post my setup, but I've still never hit the track. Work schedule never allowed it, but I'll do at least one this year.

Mystikal,

You still did an AutoX no? So you can post your setup and thoughts on it. Good thread guys...

[Mystikal]

Fair enough.

o Mildly warmed over M20 (software, injectors, cone)

o Ground Control coilovers
-o Front: 375lb/in 6" ERS srpings
-o Rear: 475lb/in 5.5" ERS springs
-o Koni SA dampers
-o Ground Control rear shock mounts
o Sparco front strut brace
o Hawk HPS pads
o New front end stuff
o 16x7.0" ROH, 225/45/16 Eagle F1/Ecsta Supra
o 14x6.5" Basketweave, 195/60/14 RT-215

I've autocrossed the car with the RT-215's and 215/40/17 ZE-512's, but not with the 16's. Overall in aggressive street driving, backroads runs, and of course auto-x'ing I'm completely concinved the car is way, way beyond my capabilities. I barely even feel worthy of commenting on how it feels, really. The venerable GC/Koni combo is excellent, and with the 375/475 combo the car understeers in steady state cornering. Any drastic throttle change can of course change that rather quickly, so I'm happy with the balance. I'll add that when I had 300/475 it was a little nervous (both the car and myself) when going past 8/10ths. I've had the rear step out almost violently due to road undulations, and any sort of throttle cut is met with an overly eager willingness to rotate. Yes, lifting is bad, but the car would REALLY bite you if you slipped. I also ran the rear perches quite high for an even ride height, which certainly didn't help the situation. The car is currently slightly higher in the front with the stiffer front rates, and feels much better.

25mm hollow bar FTW!

I dunno. It might help and solve my problem without stiffening the ride a bunch

i have susp parts all setup for track use, but my work schedule hasnt let me install the GC or attend any driver schools or track days yet...setup:

450F/650R GC springs 6" F&B
Koni SA
m3 CAB and front end links
e46 cabby RSM
IE FSB, BMP RSB

205/50/16 falken 415's F
225/45/16 falken 415's R (anticipating oversteer, so went wider in rear)

cant wait to see how it feels on the track. im expecting to look like a total noob, but im bringing my track instructor friend with me so i can LEARN.

[Axxe]

Jay, remember the ass-out shenanigans I had on my car that one meet, between installing my springs and changins rear bushings? That all disappeared with the urethane rear bushings, which I recommend if you haven't done it yet. Changes the feel of the car for the better.

Here is how my car was setup when I drove Laguna Seca a while ago.
stock m20 motor with:

H&R Sports
Bilstein Sports
ST swaybars (rear bar on the stiff setting)
BMP strutbar
e36 m3 steering rack
crappy Falken tires

Car had MASSIVE oversteer. It should be a lot better with the rear swaybar on the soft setting. I'm not sure if it would be enough though


Now, I have the same shocks and springs, but also have IE swaybars. The front bar is on the full stiff setting, and the rear bar is almost full soft. I have not had a chance to go to the track again to see how balanced it is now.

If you've got "massive" understeer with that suspension setup, then I'd suggest checking to see what else is wrong with the car. That's the same suspension package I've run for a long time, and I found a lot of understeer on initial turn in, with steady understeer pushing through the turn. The only time I could produce easy oversteer with the setup is on tighter slow speed turns. Going to camber plates up front dialed out a lot of the understeer, but on street tires with stock camber, it certainly wasn't oversteering.

Neutral all the way until you either a) loop out, or b) push depending on how much you are gassing it when it does let go.

Ska,

In regards to the X-Brace, did you believe it did anything or is it a BS mod?

Good post so far but many of you guys aren't saying if you would change anything...

Mike - This year is the first time I am acutally on the track, some of us haven't had track time at all. We have to "feel" the car's traits and identify areas for driver improvement before tweaking the car. You're the minority over here with regards to your driving history on the track.

I haven't heard any negative feedback about my car's behavior yet but next time I go to the track, I'll let someone else I trust give me their 2 cents on the car's behavior. I am kind of lucky to be able to compare all the e30s I have had set up to date with various traits and say that I am satisfied with this current configuration. My other ride is set up with Bilsteins instead of Konis and a softer Eibach ERS spring selection with an m3 rear sway bar. I don't like how that car feels on the edge. I have another set of Bilsteins I'll put on that but in a few weeks to somewhat equalize the playing field, but so far, my consensus has been OTS Koni > OTS Bilstein.

On another note, I don't think I'll ever get into full competition mode that will require double adjustables bla bla bla in a bid to shave a few seconds since I am a low budget car enthusiast who's simply lookin to have a good time :pimp:

[Skafrog]

Well, I dont think I will change anything just yet. I am using a modified version of the setup from the D-Mod car, and a lot of time and effort went into producing a setup that works well.
As far as the x-brace, I will let you know once I use it. Hoepfully I will see you guys at more club races, and we can get a chance to talk then.

Charlie, I didn't say I had understeer. It had a lot of oversteer. So, when you had this setup on your car, the rear swaybar was also on the stiff setting? I know that was the first problem. After I got home, I moved the rear bar to the soft setting, and it felt more nuetral on the street, but it is hard to say without taking it back to the track.

I now have IE sways, and love them so far. I still need to take it to the track again to adjust the rear bar accordingly because I just installed it on almost full soft.
