I was thinking of the weight when I asked. I'm not sure tire height has nearly as much of an effect on things when we're talking 2-3 inches difference. But I've never really explored this.

Both are important considerations...rolling weight has to be overcome to accelerate the wheels/tires, which cause the vehicle to launch...less weight = quicker acceleration (even fractionally!). But you see, when Ed 'n the boyz designed the Gen-5, on a larger-than-perfect donor platform, they HAD to go with bigger wheels/tires/wheel openings to get the proper "scale" and "look". Try to imagine the Camaro with smaller openings...just take a look at the '04-'06 GTO, if you want to see "out-of-scale" design... That car BEGGED for bigger wheel openings. Ed 'n the boyz fixed that...
Another "proof" of this reason: Did those 245/45-20s and 275/40-20s exist before the Gen-5 Camaro? No... Remember, the Gen-5 Camaro is about the same size as a Gen-1 Malibu! CG is "simply" a math computation of where the centerpoint of the Mass is... The lower it is, the more easily a Mass will change direction with less attitude change...and the more stable it is against any opposing force. |

Michelin PS2:
305/30-19 = 26.3" tall, 12.2" tread width 305/35-20 = 28.4" tall, 11.3" tread width...1" taller sidewall, 1" narrower tread...this is the size of the ZL1 rear tires 1" in height affords "slower" turn-in, more squirm, but a better ride. 1" more width = 4" total tread width...hmmm...gimme the 19s! Plus, 4 equal-sized tires can be rotated... Goodyear 285/35-20 = 27.9" tall, 10.5" tread width...ZL1 front tires vs. (4) 305/30-19s, that's now over 5" extra tread width in favor of the 19s! Now, shed 200+ pounds, drop 75hp, add 5+" of rubber...makes a Gen-5 ZEE a worrisome/eager combo to some (former?!) ZL1 prospects... |

Wheels alone don't affect it...these specs are as per Tire Rack: Michelin- http://www.tirerack.com/tires/tires....ilot+Sport+PS2

And a 1" (diameter) drop lowers cg, as well...
"Buildable" by GM? Not quickly, but do-able, depending on bumper height for crash-test purposes... |

I wish GM would put together a 2015 Camaro Z/28 with a 375hp TT V-6 with a weight about 3500lbs solid rear setup with 3.90 gears and a PG tranny.... and don't forget the 8Track..
I'm being very serious... I don't want Lumbar support, 8-way adjustable power seating, Navigation, Leather/Suede, 9 speaker radio system... in other words I would forego comfort for a B*llBusting Reasonably priced Camaro.... Why does it have to compete with Ford.... Why can't it be it's own Competition, be different... |

Annnnnyways.... I was reading "cg" as that of the wheels themselves (since their weight does not effect the sprung mass of the vehicle)...you seem to be talking about the car's cg? |
