as for the car, have a sit down with alex and work out what you want to achieve, then get the bits and build the car to that idea.
my mistake was not deciding on what i was aiming for with my car and it ended up a mixing pot of ideas. all good. but none leading to a final good idea.
if you want a track based car then you want maximum grip; so a decent set of tyres, possibly wider; good brakes and fluids and possibly a stiffer setup.
if you want show car, then you possibly want to slam it, mega wide wheels with either fitting or stretched tyres depending on choice. and any number of other add ons to make it look pretty.
