eganders,

The tires are Yokohama Advans (only brand with the sizes I needed within my price range).

No drop spring kit at all. Totally stock suspension. Only other upgrade as far as performance is the brake fluid and I have racing pads and rotors for the track (BIG difference in stopping power).

The traction is better in my opinion on both the street and the track. I'd have to take it to the skid pad for verification, but it felt better after driving to Las Vegas as it had time to wear off the release agent that bonds with the rubber. (This agent/rubber bonding is known to make new tires slicker initially)

The ride on the street seems about the same as the OEM sizes for smoothness.

I'll try and get new pictures posted this weekend.

Cheers!
