Here's my car. I am running the standard Cobra size tires. I removed the "EAGLE" from the side.
A few notes...
-The sidewalls were dry "cracked" from new. I wasn't too keen on that, but they told me that's normal.
-The tires were so out of round and out of balance that after adding over 10 ounces of weight on each wheel, I just pulled all the weights off and ran them unbalanced.
-They definitely grip like a track tire. You will be constantly making steering corrections as they grab everything in the road. But after driving Cobras with regular tires, I actually prefer the way the Goodyears grab, you feel more connected to the road.
-Because of the thin race tire sidewall, they leak air when sitting. I have to fill them up weekly.
-Even with the above issues, I've got over 3500 miles on my tires and they have been great. I have gone on out of state drives with my car and it drives fine with no problems.
Hope this helps.
