For the $3K ($4K in Canada) savings plus the money from the sale of the OEM wheels/tires, I can choose the wheel/tire combo I prefer, increase HP/handling with bolt-ons, add a spoiler for looks and outperform stock Z's on the street with the sports pkg. Frankly, I like the look without the spoiler. Up here in the GWN (great white north), your base pkg is our touring model which comes with the LSD. The SRM is a nice feature but not necessary for the street or adept heel-toer's and won't make your Z quicker. I know most in here have the sport pkg and you have your reasons for spending the extra cash. But from a cost/benefit approach, I don't think it's worth the money unless you track your car (because you'll need the bigger discs/brakes). The base Z is still a very nimble car and should get you out of tricky situations where lesser cars woould't. Anyway, they are my reasons for not opting for the sport pkg and hope it helps for prospective buyers who may be on the fence as to whether or not to opt for the sport pkg.
