I chose the base non sport simply because I new I would change out the crap I didn't want anyway so why pay twice and it was a 6k difference in price since I bought my 11' in May of 12' brand new. The diff I changed out, the suspension is completely different. I upgrade stuff when it needs upgrading. I autox my car and built it for that, so far the only thing I regret not getting the sport package for is the rims and brakes. As the brakes now are the next thing on my long list of stuff I want or need, which I am pretty sure I will be getting the Z1 upgrade package.
The SRM is a nice feature for people that are still learning how to drive a man tranny.
my feet are the right size to heel toe properly with the small azs go pedal.
