i have a 05 stratus with a kick ass warrenty 100000 miles or 10 years so i would like to put some performance stuff on there and lowering springs and i would like to kno if there is anyone out there with some knowledge on stuff i can do that wouldn't void my warrenty thanks for looking

if you lower it, you will void your worrenty. b/c/ let say that a breakine breaks, they will say that was caused by the lowering. 8mm plug wires. exoust system. thats really about it w/o voiding the worr.
