Well put.It depends on what he wants....actual cornering speed vs ??. Reason I suggested dampers is because from what I gleaned from his post, he wants his car to "feel" more sporty. Sway bars don't necessarily make your car any faster through a corner, they just change the front/rear grip balance and can add an athletic feel. For competitive, 10/10 driving sure tires come first assuming all the other bases are covered; healthy shocks, bushings and performance oriented alignment. But for a improved daily drive and all-around composure, dampers are king. Then everything else after that. It wouldn't make sense for me, personally speaking, to drop $800+ on some sticky tires that will probably have unfavorable wear, noise, and riding resistance characteristics, while riding on the stock (relatively) sloppy suspension. So it necessarily all comes down to individual priorities but IMO the dampers are usually the weakest link in most suspension setups, coilovers included.
OP, give us some feedback on what you want to do. We love spending other peoples money
A lot of shop have bad information about the MK6 jettas. I am glad you didn't order the sway bars based on their word.
