low center of gravity?

How much does the ride height affect the center of gravity in drifting? Most people say it has little to do with it but not much. I want a clear answer from Zilvians since you guys have a lot of low height drifters.
I'm happy with my drop. It's low enough to look nice and drive comfortably in DD (still hard to go over some bumps.) .5~1" would give me pretty slammed look (very hard time going over bumps).
So, If .5~1" drop won't affect much in lowering center of gravity, then i prefer staying with my current drop.

well think about it this way... if say a truck tries to drift with it's height what happens? it rolls over right... so the lower you are the less chance of you rolling on to your side

Unless you lower the car so much none of the suspension arms work properly causing the car to roll more then it would if it was raised up.

Center of Gravity drops linearly with ride height. So if you drop your car 1", your center of gravity drops 1".

What 95KA-turbo is getting at, though, is that going really low affects much more than center of gravity.

You may want to do some reading here:

I've talked to an avid drifter/autoXer who is an engineer, he said from certain amount of drop, the suspension geometry(?) will change and throw the handling out the door. Just like 95KA-turbo said.

EDIT: i finished reading the link you provided. Unless you have aftermarket lower control arm or subframe adjuster that has roll center adjustability, slamming your car won't give you better performance? If so, i doubt anyone really has that mod..well, for 350z owners like myself.
Shouldn't you have lowering subframe adjuster rather than rising adjuster for slammed cars?

Luckily you have a double wishbone front suspension, which isn't affected nearly as much as an S-chassis's McPherson strut. I would say slam away, haha.

But there are a couple companies making control arms with RC adjustment out there, but they're expensive.

Parts Shop MAX is coming out with a pretty cool super angle/roll center kit very soon.

And on the adjusters, think about it. You lower the car, but you wish the arms on the subframe were like if the car was higher. So you raise the subframe.

350z has double wishbone sus? hhaha i though they are mcpherson
Now i get why you have to raise the subframe. thanks is it like if you drop the car 1 inch then you raise the subframe 1 inch?

haha, no man, you don't want thing to be too different front to rear. Just raise the subframe so it's flush with the body. That should be fine.

When you raise the subframe you are trying to get all your rear arms as close to paralell, as possible to the gtound .At super low ride height

sikky sells the subframe bushings that raise it for about .65" what would you do if you want to raise more on 350z?

You cant really. the rear of the sub frame is already flush with body, and sikkys bring the front part of the sub frame closer to the body. Unless you want to do some crazy modding and rewelding mounting points.

^^^ This /Thread. What else do you need to know kid?

If you want to look at the dynamics of the vehicle as a result of lowering your car that's a whole different area. Weight transfer, suspension geometry, etc will change.
