Personally, I love my new Falken Azenis PT722 A/S. I had a set before but the new ones obviously have a different carcass than the old ones. One of the things I like about them is that even though ultimate grip may be sacrificed a bit, the breakaway is so progressive that it's easy to tease the limit.

My car is properly lowered using good stuff and carefully researched alignment specifications. I drive very aggressively and keep my rear sway bar in the full stiff setting so I hang the tail out a lot. The last set lasted three seasons of brutality. Ultimate treadwear huh?

Anti-roll bar ( stabilizer bar ). An anti-roll bar (anti-sway bar, sway bar, stabilizer bar) is a part of many automobile suspensions that helps reduce thebody roll of a vehicle during fast cornering or over road irregularities.

It connects opposite (left/right) wheels together through short lever arms linked by a torsion spring. Anti-roll bar is intended to force each side of the vehicle to lower, or rise, to similar heights, to reduce the sideways tilting (roll) of the vehicle on curves, sharp corners, or large bumps.
