Almost none and none, dropped on H&R springs and still have a little more room to go.

You running 275's on the stock Sport wheels? Or what are your front wheel width?

Yup stock wheels, no fitment issues what so ever

greatly appreciate the info :tiphat:

yeah i will be running 285s for the rear, just switched my order to 255 for the front since they cant get a set of 265s in time for my trip so i will have to see what happens. :tiphat:

I'm assuming 275/35 or 275/30s?

I'm on 245/40s and rub on big bumps. dropped on H&Rs.

275/35 also dropped, but am still going to go a few mms lower ;]

I would go 265/35 up front & 305/30 or 315/30 in the rear.

That wouldn't be very proportional with 315 in the rear. In my opinion 305 is the biggest that should go on the rear wheels anything else starts to look a little much. but 265 and 305 together wouldn't be too bad

When I replace my tires I'm going to go with 265/35 in the front and 305/30 in the rear. I believe there are some people here that are running 335 in the rear, but far from few are doing so.

275/315 on stock camber and suspension with aftermarket wheels.. Little bit of rub when I hit a good bump.

I had 265/295 in PSS I returned them for OE sizes after 1k miles, and still was pissed, just watch if you are on stock wheels and which tire you choose, the "god" PSS have stupid soft sidewalls and turned the Z into a jalopy from sidewall flex. Stiffer tires will be ok, I and running BFG SC-2 in the rear now, they are not as sticky as the PSS but the sidewalls are way stiffer, I would feel OK with 265s in the front with the BFG, which I currently still have the PSS in the front, which I will throw away in the spring unless someone local wants them, that's how much I despise that tire.(yes I know BFG is owned my MIC) Next set after the BFGs hands down will be RE-11s with 265/f 285/r. Unless its for looks wider is only need for more power in the rear, I still want to have a little fun, don't completely lock down the rear :)

I have 265/285 S-04s waiting for spring.

Joe, sorry about your PSS experience. I enjoyed them on my Mustang. Never had them on the Z. I hear the S-04 is a lot stiffer so I'm interested in seeing how they behave.

I love my PSS's on my Z.

I had the s-04s I like them, and though I was stepping up with the PSS...I would do the s-04 again over the re50 or pss, no hesitation. Bridgestones usually has stiffer sidewalls.

Interesting.
