Just put 4 of these tyres on, replacing the GSD3's. I've done a couple of hundred miles and they are fantastic.

Low road noise, excellent grip and traction, especially on bends. I would definately recommend them as a replacement for the legendary GSD3's, which have now been discontinued by Goodyear.

I had one problem though. When I had them changed I decided to get the alignment done but they couldn't free a bolt, for the tie rod I believe. The fitters said it was seized and didn't want to apply any heat as it was so close to the strut. As I was short on time I said I'd return another day when they could take the wheels off and have a proper go.

However, I did manage to get a printout of the current settings. I think that the previous owner set up the front camber for a more aggressive cornering capability. It's on -1.2 when it should be around 0. Correct me if I'm wrong but apparantly this is a prodrive setting for fast road use?
