Well, not many JUST track their car, but there are a lot of daily drivers. I can only speak for SRT's, but the basic mods for an SRT have been constant. Some sort of CAI, a Pulley, some sort of Intake mod, and a tune to bring them all together. Some or should say many different approaches to improve cooling. None of which have really completely solved heat soak problems. I just read and follow some the guys that are doing this. We went through the rear end issues, but only a handful of us fixed the the diff problem, others are content to take the risk, some have lasted a long time. Way too many personalities taking their own paths to gain HP...some are good, some are a waste of time. But you never know until you try I guess. So, bottom line is, we can't even agree on mods let alone a thread...
