Right out of the gate, the biggest improvement are summer tires. I've almost ditched my car three times trying to do 0-60 runs using my dash computer with those horrible, worth for nothing, OEM all season tires. Any amount of solid launch, those tires break loose and my Stang swings out. I will not do street light runs against anyone during time period between late fall and early spring when I'm running the all seasons. When April swings around, the summer tires go on, and my launches stay straight and smooth with just the right amount of modulating pedal. To hell with those BMW's.....I'll lay waste to them all (unless they're the $100,000 plus versions)!!!
P.S. LCA's/UCA's and aluminum driveshaft's can increase noise and induce gear whine. I put a aluminum one piece driveshaft on 14 GT/CS and it created some annoying gear whine. I took it out and reinstalled my factory driveshaft, and bam, gear whine gone. It all comes down to individual vehicles and how each one reacts to suspension/drivetrain mods. Some handle them well with little noise, and others, like mine, roar like a Banshee!
