I just got embarrassed by a hipster in a Tesla Model 3 from a stoplight. I am in a mostly stock 2011 V Coupe A6 on Michelin Pilot Sport 305/35 ZR19 rear tires. I can barely get good traction from a launch with those, I was spinning my tires while he was zooming ahead. I love building more power and going faster but don't understand how I can get quicker if I can't get traction. The Hellcats have a lot more power but aren't any faster 0-60, they can't gain any more traction on street tires. I am like everyone else here and want to mod my car and take advantage of it's capability but if I can't translate that power to speed anywhere other than the track on drag tires it is of no use to me. The mods I have budgeted for will give me an extra 100-150HP but I don't see how it is useful on the street if I can't transfer it to increased grip, I will just be able to do more impressive burnouts. Those tires of that size aren't cheap, lol.
