I have a similar outlook, but went a completely different way. I want a great street car, so I went with a Touring manual w/ Sport. For me, it was comparatively cheap way to get a lot of performance I want without having to replace anything.

I love the rev-match feature even though I used to be a manual snob. I realized quickly that the rev-match does allow you to concentrate more on driving, even if heel-toe is second nature. It took a few miles for me to stop reaching for the gas pedal to blip the throttle, but I see the light and am very happy that I have this feature. Downshifts are very smooth and never upset the car, allowing you to get on the gas a little quicker than normal. I love the leather/suede interior, upgraded stereo and the aluminum pedals are nice. It's a street car and the added weight is worth the comfort for me. If this isn't the case for you, I suggest the base w/ sport package at a minimum.

The 370Z has a great chassis, and great brakes. I think most would agree that the part that needs to be addressed the most as a street car is the power. A lightly modified street car will likely simply start as a Sport equiped car with intake/exhaust and maybe a light flywheel. You don't really need to touch the brakes unless you 1. didn't get a sport pack (which I'm suggesting against here) or 2. measure you cars performance by the number of aftermarket parts on it (which is dumb).

Those that track their car may want to upgrade their brake and clutch lines and grab an oil cooler/diff cooler, but won't really need to touch much more than that besides super sticky tires and put the car on a diet.

Of course the over the top cars that will be stripped down and built up will obviously not be using the good-enough-for-most parts as they measure their performance in tenths of seconds and every advantage counts. In other words, all out race cars.

I guess to sum up, get the sports pack unless you aren't an enthusiast (why are you here?) or are building a track monster.
