Z's with 19's & 20's
 

I'm thinking about getting some wheels for my Z. Is it a big diiference in the ride quality? Any downsides at all? Please make sure you specify wheel, tire, and suspension specs! I appreciate it :)

I'm running TSW Thruxtons (20x8.5 and 20x10) on 245-35 and 275-35 rubber. My only issue is with the reduced acceleration. It's not substantial, but I do notice it.

I went from stock 17s to 20" Axis Seven Mod with Michelin Pilot Sport A/S 255/30 front and 285/30 rear, lowered with TEIN Basic coilovers, and new Cusco sway bars. Ride quality is virtually same as stock but much tighter in the corners and a little slower acceleration.

Why not do 18's or lightwieght 19's, doing 20s will hut your speed (basicly what a sports car is for). Never understood 20s on anything but suvs and show cars.

The look of 20's on the Z is worth the slightly (and I mean slightly) reduced acceleration. If I were into tracking or dragging the Z, 20's would definately be out of the equation.

I went from the stock track wheels to 19 X 9.5/ 19 X 10.5". I already had JIC coilovers on the car so all the fat rubber (255/285) did was reduce understeer some, the ride didnt change much at all for me....
