I'm used to reasonably light cars, my current car the Mr2 Turbo and whilst the power to weight of the 370z is a fair bit more than the MR2 even as standard it weighs ~120kgs more, this along with the FR rather than MR layout makes the Z feel a lot less nimble through the turns- I really love the look of the Z and i'm really keen on getting one but i'd want to drop some weight to get the most from it.
Just interested to hear what others have done for weight reduction, not flaming on the car!
