Just bought an Astra 1.4 P registration for £400 (Nothing special I know). Everything on the car is sound and there don't appear to be many problems. However I get a scraping noise when I am braking from speed and the car wobbles like hell. I am intending to change the brake pads over the weekend but not sure what to expect. Anyone else seen anything like this?? I want to do a lot of work on this car and spec it up if possible. Can anyone give me any good advice on it?? And also what size tyres are best. Currently sitting on 155's and they are far too thin.
