i've dealt with both those springs before. and i vouch for eibach and their line of products. great quality all around. the sportline and pro kit is honestly the same as in ride comfort. it's just that the sportlines drop the car a little more. and honestly if you threw in the pro kit, with stock shocks i almost 100 percent positive your struts won't blow, heck they'll still feel like a stock ride, but with some struts it'll feel like a whole new car in handeling. you'd only need an alignment with the pro kit no need for a camber kit. and plus for 100bucks i say go for the springs.
