Hard to say...

Because if you're going with a taller tire then stock on a heavier weight wheel then all those aspects will probably suffer in a negative way.

Now if you're going with a tire thats near, or really close to stock height on a lightweight racing wheel like Fikse', then you will probably improve in some of those same areas in a positive way.

"technically" the wheels can be heavier,a dn the "mass of the wheel" is further out and adversly effects the straightline performance of the car . . .

But if you are really that worried about it then don't get them.

Cornering wise, an 18" is going to help since there is less sidewall to flex.

Also, I STRONGLY suggect 18" on all four corners. IMHO 17 /18 combos just look wrong on F-Cars.

no, as long as the tires arent wider than a 315ish in the back and the wheels have the right bolt pattern to fit an fbody.

All depends on the size of the rim you're talking about...

For a 10.5 like you're looking at - I'd say at least a 305. Most tire manufacturers I'd say would recommend a 275 for a 9 - 9.5" rim, while a 295 or 305 is recommend for a 10.5" rim.

You can pick up a set of good looking C5 z06 rims for 599 @ TomzWheelz. He even puts on tires, balances etc if you purchase them together.

Go with 18x9.5 (275/35/18 tires) all around for no mods, direct bolt on
Go with 18x9.5 front (275/35/18), 18x10.5 (295/35/18) rear for best looks and more "grab", only requiring you to trim the bump stop in the rear. Many write ups on this--even on google.

Nothing against 275/35s, but IMO if you're at stock height and are running the 9.5s - get a 40 series tire instead of a 35. The extra sidewall isnt 'that' much of a difference, but personally I like it. And you typically wont get the "lower that 4x4" comments with the extra % of sidewall height (least I never have lol)
