Something to consider here is the weight of the vehicle. If you want to get it sideways, I have no doubts that a 300 ZX is more than capable. However, I'd like to point out, that the stock suspension isn't something I'd trust to the task. You'll want to lower it some, as this will improve center of balance as well as increase even lateral acceleration.

In addition, it being a used car, it also has to be pointed out that you'll want to really get that LSD locked up, if you want it to really work as a drifter. You need to have both wheels spinning at approximately the same speeds and with a semi-locking diff, this is going to be more difficult. What I've heard about 300's is that they will, with a bit of coaxing, right out of the gate get sideways pretty well. But the weight factor is something to consider. Lighten the load in the rear end and remove non essentials from the front end, to offset the weight of that big six.

But the reason I mention it is that you'll want to be sure that the diff. is up to the abuse. Yes, I said abuse. Your differential is likely (besides your tires) going to be one of the most pummeled parts on the car, when your drifting. And without it, you don't drift. I should say, if it's not locking, you don't drift. If for example, only one wheel is spinning and the other is not... What happens?

This slows the rear end more than it speeds it up. Sure, there's loss of traction, but the idea here is that one wheel is going to fall back into it's load circle and the other is going to be on the outside of it. One will begin dragging, while the other is attempting to propel.

So you want to focus on that LSD and get it to KAZZ or something. Know any good shops down in Oaktown?

In addition to a decent sport suspension or performance suspension that will allow you adjustability of your toe in, toe out, camber neg. camber pos. etc., focusing on your LSD, something else would be important.

A clutch. Drifting, especially the way I do it, is hard on transmissions and clutches, mainly because I like to double clutch and clutch lock allot, as I didn't have an e-brake worth a crap in most of my cars.

Kevlar street/strip clutch is something I'd recommend. Yes, they're a bit pricey, several hundred dollars, but they're well worth it, to prevent being stranded somewhere without a tow vehicle, or if you happened to be out in the mountains on an isolated road somewhere. Speaking of which, something most people don't consider, is having a few spares of parts easy to break while drifting. This will facilitate a faster fix, when out somewhere. Carrying an extra set of tie-rods for your steering, or ball joints, in case you curb it, or if you happened to snap an anti-sway bar... You get the idea... Nothing major, just some stuff that will prevent you being forced to call a tow truck, or have your car stranded for days on end. If you do it out somewhere in the middle of nowhere, be careful... And bring a couple friends, extra vehicles.

Also, check out the information on my tribe, Project-D, there's an article there on being sure that you're setup in the cockpit is correct, so that you find it easier and more comfortable to step outside the realm of straight and narrow. This tribe isn't old, but I'm working on getting more information into it.

Peace.
