Need autox alignment suggestion/specs: 285/35 19" Sq. tires, stock suspension

Fishey

Lockout kits are entirely a waste of money and not needed...

The important thing is to properly lube/clean the rear bolts so they properly tighten the adjusters. I see cars with a ton of corrosion in the threads and even tight they are not really applying proper TQ to hold the eccentrics in place.

synolimit

Disagree. After a few times of slippage you'd torque as tight as you could to correct the problem but my friends still have issues. If you read what I wrote its not a waste of money.

At Wilmington autox last weekend I ran stock camber front, 1.5 rear, 0 toe front and 1/8 total toe rear. Car was surprisingly neutral, maybe a touch of under steer that given more time I can dial out with tire pressures and shock settings. Using 275 square ad08rs on stock rims with front sway for c street class.

Thanks man. So 1.5 rear is what I'm doing. I guess only difference is you have 0 front toe and 1/8" total rear where I'm thinking of 1/8" total front toe and 0 rear toe. I have been reading more and more about how having a little out front toe helps turn in during autox. Do you think with toe out, your car will handle even better? Hows your highway driving stability?

How did you like your alignment setting?

I ask because I'm having my alignment checked. I run BS in autox, with Konis and hotchkis front bar, sport package, but 18" wheels (F14s) on re71 tires (275/35 square).

Current setup is as follows:

Front camber: -1.25/-1.0 (not adjustable)
Front Toe: 6min toe out (.1 deg, .031in)
Rear Camber: -1.75/-1.75
Rear Toe: 18 min toe in (0.3 deg, .094in)

It was suggested (by an experienced, but non-370z guy) that I should change rear camber to -2 and rear toe closer to 0. After reading up on here, it seems like people say -1.5 or -1.8 is better.

I was thinking of making the following change:

Front: no change
Rear Camber: no change
Rear toe: 0-5 min (.083 deg) leaning toward 5

What does everyone think?

zpower86

I ended up only changing the rear toe to 4 min toe in. Took it for a test drive in an abandoned parking lot and it seemed to do better in a sweeping turn. Nothing drastically different, but it rotated slightly better. I'll know for sure after the next autocross.

Ok how we supposed to figure out toe length when machine does degrees?

But where's the measurement coming from? 1 degree at the hub wouldn't be 1 degree at the rim. I don't see it being 100% accurate every time.

Any flat edge on the face of the wheel can be used to measure toe, at the track here is what we use:

Do you still go to NNJR at Metlife? I have seen a few Z there, but never got a chance to speak to any of them.

AK370Z

Yes I do. I was there two weeks ago and won class on wornout re-71rs! It was a course I loved driving... Though I run Philly and SJR more frequently, I do try to go NNJR. It IS 2 hours away from me. I know a few Z owners from forum run there. One in BS and one is SM?SSP? can't recall. But both are SUPER NICE. Both came over and shook my hands. Great members.



I should mention that i'm NOT on the setup that I have asked question in the first post. I'm on koni yellows, eibach front full stiff, 275-35/19" RE-71Rs all around. With 96,000 miles and 160+runs already this year, Z is def. feeling the age. Still on oem clutch and everything from day 1. I must say, car held up very well. I'm coming up to almost 400-500 autox runs.

Cool....I wasn't aware of that. I was there also. I think we need a Nissan paddock area so we know who is here.

Next event 10/10 Lot E!!!!
