I've replied to this question before. I researched the two as you are.  I choose Steeda.  Didn't want too low, and since I pull a boat, I liked the rake that levels out some when trailering.  I've had them for 3 years and about 40K miles. Very satisfied.  Occasionally load up the crew for a weekend in the mountains.  With 5 adults and luggage for the trip, it handles the Blue Ridge Parkway surprisingly well.  Steeda does everything I need them to do.  More often it is only me in the car, and I love swooping on and off ramps.  Car handles noticeably better than stock. Yes, a little stiffer, but I didn't buy the ST to feel like I was driving a Crown Vic.  My .02
