Suspension problem

Red__Zed · 08-07-2011, 12:08 AM

Calm down, and use paragraphs. For the tracking issue, they probably didn't align to straight. Common mistake, 5 minute fix. Have them do it.

Specs are same on nismo as on the other models, so they are right on there.

Do you have a results printout you can scan in?

Bad toe settings can definitely make your car feel floating and twitchy. Make sure they tightened everything down after making adjustments.

Do you have any aftermarket suspension parts or is it stock? There are limits to what the stock parts can be adjusted to (no front camber, limited rear camber and toe).

Here is the basic alignment specs. The Nismo is the same except it runs a little more camber (which helps chew up tires unfortunately).

Nope, it's all stock.

Sorry about the jumbled mess of a post but I'm using an iPod because my stuff hasn't been shipped from Guam yet by the navy.

So the nismo has the same specs? I had not realized that, I was ways told/read that the nismo model had not only had stiffer coilover and dapeners but also a more aggressive camber and toe as well to make it more track worthy.

Now I understand that those adjustments can make the car feel floaty or whatnot but keep in mind it's even driving in a straight line. I will get over 80-90 and the car will literally start wagging it's tail and front all over, and there's no tire squeal so it's not breaking loose, it's the car itself moving all over on the suspension and it's almost impossible to keep it in control. If that's really toe then I'm amazed at how much of a difference that makes lol.

Toe can make all the difference in the world. The HRF I'm looking at says the Nismo uses the same specs--could be wrong though.

Toe makes a huge difference in stability. I run zero toe up front to help with turn in, and the car is significantly less stable at highway speeds than before.

If you post up your alignment sheet that might be helpful in giving advice.

Almost sounds like they gave you rear toe-out instead of toe-in, that will make a car feel really twitchy. It's common to have toe-out on FWD cars but our cars require toe-in for mid-corner stability.

I don't think that you can even do that on the Z-- not enough adjustability (at least on mine)

i know the tires being oversized will also effect it but it shouldnt be too drastic of a difference when adjusting for alignment right? the new tires are 265 30 19F 305 35 19R .

how do you compensate for that? because there just going to do what the machine tells them too "within error and laziness more or less" and its assuming you have stock tire sizes.

The alignment hardware is attached to the wheels, not to the tires. Tire size shouldn't be an issue, I run the same sizes. What did you put on for tires?

That's good to know. I know if the car is lowered that is most definitely the case.
