Re: Question about ford focus tires
Michelin makes some OUTSTANDING street/track tires. As mentioned though, you do pay for them and they often have a very short mileage life; upwards to 20K if you baby them.
I ran some slicks for the track with my old '90 5.0L GT fastback 5 speed. I can't say I've run bridgestone tires on anything but my old tractor trailer, as they gave me EXCELLENT mileage for the size and price. Again, I can't compare apples to oranges, they might both be fruit, but are eaten differently. I recommend Michelin. If your budget is a bit limited you can try Toyo, they have good high performance tires for the money, but Michelin is tops in my book.
