lunarhighway - Astra has 0.29Cd, that's not bad - explains why the car is rated at 80 MPGuk on highways... wouldn't be surprised if my car has a Cd of 0.26.
vtec-e - So inflating it high = less grip then? I've been told inflating it high = no change in grip. That's probably why the car's a little skittish around corners... Yes it's definitely the horn, btw.
