Please read:

I lowered the car a little over a month ago with rsr down springs and tokico d-spec shocks, both 350Z versions. I love moderate speed street driving, however at high speeds (hiway), the car does not seem stable (I drive 80% hiway). On the stock suspension I would jerk the wheel to switch lanes at high speeds (70-80) and the car responded great. Now when I do that, the car sways a little even after the lane change has already been made (like its stablizing itself of something!?)
Also, when driving constantly (40 mph) on hiway on/off ramps, the anti slip comes on (w/ light on dash) and holds/jerks the car back.
I know my camber is off and I need more toe-in. Is this what's causing it? Could my Tokicos be defective? The shocks are set at 4 turns from full hard.
I love the look and ride comfort, but I feel like going back to stock. (Though it will be hard after seeing the car lowerd!)

1st alignment 4-6 days after drop. 2nd today 3/13.
Please tell me what you guys think?

 

Are you rubbing at all? What size wheels and tires do you have?
Hard to tell whats going on. I recently dropped my car as well but with just springs (espelir gt-.5 drop all around) and my rear wheels rubbed when I turned and launched the car. I had my fenders cut and now its fine.
Your problem could be caused by lots of different issues.

 

Yes, I agree that it can be many issues. I currently have the OEM 18 wheels. Fortunately no suspension noises and no rubbing whatsoever.

 

Fix your rear toe. If anything, your rear tires will wear quick if you don't fix that. I set my total rear toe @ 0.00.

I used to have tokicos and didn't like them. I thought they were slow to react to what the car was doing. Maybe you should set them stiffer.

 

Your unstable feeling is your toe. Give it about .08 degrees total toe-in up front and .16 degrees total toe-in out the back and you'll notice a big difference. I'm not sure why they gave you so little! I autox with mine at 0.0 degrees up front and the rears the same as I recommend for you. The front toe set to zero gives quicker intial turn-in but definatley can feel 'wandery' on the highway.

 

triniG35- what swaybar setting are you using? are you on factory
swaybars? if so, i'd go 3 turns from full hard. if not, i recommend
you get a stillen set. your springs are probably too soft.

You definitely need more toe-in on the rear. the FINAL(AFTER)
setting doesn't even look like your alignment shop did any work.
it's almost like a reflection of your INITIAL (BEFORE). Did they even
align your car?! they seem to fix the front toe-out and that's about
it.

Here's what you want to aim for (this is more for tire wear):

Front toe: 0.03 each side
Rear toe: 0.08 to 0.10 each side
Camber: -1.5(rear-only) within 0.2 degrees left and right

If you have a-arms for the front, i would set it at -1.0.

 

Thanks for the replies. I figured my toe had a lot to do with it. Ken, are you saying that more toe in = more tire wear? Cuz I do a lot of driving, esp on the hiway.
