Just got my Viper a couple days ago (2010 ACR Voodoo #2). Love it! A few minor issues like hood/trunk air struts that need replaced. TPS on wheels probably need replacing as light on and tire pressure okay. Tires are 2015, michelin Pilot and have no observable wear. Does not feel like the tread has hardened. Total miles on car approx 9700 and these are second set. Are they too old to take to track days? I am at novice level. Hate to replace what look like new tires, but may based on age.
