if you knew anything about coil over your would know that the ride better than stock
i put eiabachs on my first jetta (sportlines)
sportlines and pro kits are not alike a prokit gives you closer to stock ride feel sportlines are a stiffer spring and ride like a stiffer spring but feel good none the less
and on my second jet i put on kw coilovers on it, they ride like a cadilac and i can put the oil pan on the ground.
its all up to you dude
