[CL9] Another suspension related question

In his case, the rear right has 0.5 more negative camber, yet his rear right is the one that is higher. That's why I believe it is more on corner balancing as the wheel that is more tilted from camber should end up being slightly lower.

The difference in front height should be that the drivers side is higher than the passenger side to compensate for the driver when they are in the car, if the passenger side is higher than the drivers side then you should be annoyed![/QUOTE]
For corner balancing, the height setting is actually in reverse. The heavier corner is set to be lower so that when you place a balance scale under that corner, the suspension pushes down on that corner a bit less and hence reads a lower reading eventhough there is actually more weight on that corner.

Look, the car is stock height ATM. And I'm looking to order a set of new rims, Sparco Assetto Gara's in bronze to be exact.
Obviously the gap neeeds to be reduced a bit.

However.
I've got a farking cusco type 2 lower strut bar. So my car al already 1 inch approx closer to the ground than the rest of youse... Stock

So if I get a coilover that drops 1.5 inches +.... I will bottom out and cause damage... Not to mention defects.
Im thinking the max I can drop is .75 inches there about (because then I'll still be 1.75 inches closer to the ground. Fml

I'm not going to track the car and it's already scraping every day, so I think need a firmer suspension or something to counter the scraping...

Or is the existing scraping caused by deterioated OEM shocks (cars on 130k km)???

The Cusco Type 2 bar scrapes even on stock suspension height. I have the Type 1 bar and scraped the hell out of it even when it was at stock height.

I just re-read the original post about the height difference and he says his two fingers are looser on the drivers side - this would tell me that the neg camber on that side is greater meaning that the tyre is further away from the guard. SO the height is basically the same but the tyre is further away from the guard. Don't think height, just think clearance and the tyre moving in an arc.

I'm not sure you are getting the dynamics of the corner weighting though. No matter the height position the spring rate is the same. When you raise the drivers side it is to compensate for when the driver is sitting in the car - this increases the loaded weight of the suspension and lowers the ride height. The spring isn't varying, only the weight on that spring is changing.

Think of a see-saw with a tall weight sitting above the fulcrum point - if you lift one end of the see-saw a small amount it will start to move further than the initial movement because the weight and centre of gravity is moving away from the raised end and on to the lower end.

Move this onto corner weighting a car and you have a similar reaction - lower a corner and it brings the weight of the car towards that corner. Its easier to see on a car that has 50/50 weight distribution like a 350Z or even VE commodore - lower the rear only and the front ride height raises.

***Mods, if you would like to move this to another section i understand, we are a little off topic here***

sooo jordiiisme, you wna post a pic up of your car with the spring shock combo? :)
