Nope… you’re wrong.

"264/40 rear" Probably 265/40?

That should work, but 265 width is a little rare while 275 width is more common. Actually, your 265/40's are probably nearly the same as 275/40. The difference between these two sizes often is just a proprietary measurement that is exlusive to the tire manufacturer.

Obviously I meant 265/40. 275 on a 8.5" rim is silly and pudges too much IMO. 265/40 is a great fit...

there can be significant differences among even 275's from varying manufacturers, and of course the final # depends on the wheel its mounted on

Good point. Nissan recommends using a Nismo 9.5" wheel with a 275mm tire width.

Your suggestion: 265/40 on an 8.5" wide wheel has an advantage: The wheel protector on a 265/40-18" tire provides great protection for a 8.5" wide wheel (saving it from curb rash in many instances). A 9.5" wide wheel combined with a 275/40-18" tire is very vulnerable to curb rash.

Very true. You must look at the tire manufacturer’s specifications to see the actual size. You should also realize that the overall diameter is measured at the tire’s maximum inflation (usually 40 psi or greater), and not the inflation that Nissan recommends for the Z (35 psi).

You don’t need to worry much about the wheel width size as long as you remain within the tire manufacturer’s specifications for the wheel width on which you mount the tire.

whutcha do in hard turns like that... such as I do on the local 422 that has a very nice wide left turn at a good 65... is pull the ebrake slightly and let the rear start to come off to the shoulder, than downshift and get the power up lettin the clutch fly... nothin says hi cops like drifting past them!

So... what sizes are your tires?

spike man, i run like 315's steam rollers... but i think i am gonna go even more for that steam roller look by just cuttin one of them freaking rollers in half and welding them onto that spindle back there to make it real steamies... nah man I'm just on the factory wheels, 17's, and I pay only 100 bucks for falkon all seasons mounted and balanced, and they ain't too grippy, but the fronts grip good, so it easily lets the rear slide when I want it to.

Cool...

The best part of the Z is you can do whatever setup you want to get the handling characteristics that suits your driving style... and you certainly have a unique style.

Nice to see a non-conformist who makes the statement even when driving.

Keep the cool,

If you do decide to go with grip, you’ll absolutely love driving the Z. This car is designed to stay put and rigid when you mount the right tires. There is nothing more fun than hitting a turn fast and hard, riding towards the apex, then a fast downshift, and pushing the accelerator to the floor as you hit and go past the apex and onto the straightaway with lots of power with this car and its high-torque engine. No drifting.. just great straight line driving.

It’s all about the tires. The car performs very well with the right tires.

Add about 250lbs to the truck and it will be neutral.

So... date a big girl... always take her with ya... and if she asks why you always make her lay in the trunk... just tell her it is because you are ashamed of her...

I'm just playin, don't mean to offend noone. And actually, I do pretty much that same thing spike, only I downshift before the turn =) and power all the way through it on most of em, just cause this car can... and all them 240SX wanna drifters can't.

Everyone has different opinions on car setup, so you'll pretty much always get different answers. But with that said, here's what's worked for me so far...

So far, non-staggered tires has been the best overall change, with the sway bars (both front and rear are set to full stiff) being a close second. Overall I think the tires helped more in eliminating understeer, but the sway bars helped improve the steering feel a lot too.

Normally, I'd rank coilovers right up there too, but the coilovers I chose are relatively soft. The Z is my daily driver and will be for quite some time, so I wanted something comfortable.
If you went with a higher end coilover setup where you could adjust the dampening, spring preload, etc.. you could also fine tune the handling with those adjustments as well.

Justin... Are the sway bars you mention swapping the OEM's for aftermarket (I'm guessing yes).
