As a follow up to the PS1 and run flat debates and by no means is this directed at Bird; the PS2 is the better all around tire. If you know how to drive, know that when it is cold you don't try to kill it in every gear, when there is water on the road you need to be careful, etc...you should have no issue with a PS1. I have had them on nine Vipers, all with no issue, but I tend to use my brain just after pushing the red button.
If you are a Fast and Furious kind of guy, I would just as soon not sell them as I don't want to have a crash on my conscience for selling tires to someone that didn't use their head.
If you have a GTS, you have had the equivalent or much worse on your car. If you have a Gen 3, this is what you have already.
If you are wanting to track the car and bang 1.60's or better, this is not your tire, unless your last name is Furman and you are at Englishtown.
I hope that helps with everyone's decision.
