[QUOTE="Voltwings, post: 16359178, member: 155561"] I'll ask you again, how much track experience do you have? Go put sticky R compounds on a car without adjusting the suspension to compensate and come tell me how it drives. You'll pick up some time from the stickier tire actually being able to handle the heat (that's a factor that's independent of overall grip) but it wont be near what you expect it to be, and is not worth the trade off in unpredictability. This is a very simple concept. A car taking a set in a corner will have X amount of body roll before the tires lose grip and the car starts to either push or oversteer (we're also ignoring bushing deflection and differences in suspension geometry and camber gain loss under compression in this scenario). When you have a sticker tire, that point comes later, so the body rolls MORE before the grip is lost and you end up with "snap" conditions as the momentum suddenly overwhelms the tires (again, ignoring camber gain / loss and the fact that the car is more likely to end up on the outside shoulder of the tire at this point). The same is true for changing directions, you end up with very abrupt, sloppy, and unpredictable handling. And again, going back to my original point, this would be more apparent in a car like the challenger because there is so much weight in question, but you'll find similar behavior even on a miata. I only made this comment to discredit the post saying adding a sticky tire to the hellcat would have it running in line with the others, because it just wouldn't. [/QUOTE]
