different companies will shoot for different markets when designing aftermarket springs for a vehicle. You have to look at the spring rate as well as how much they will lower a car. Personally i went with the Eibach's because of the progressive rate so it would be a decent ride normally but if I wanted to have some "fun" i could throw it into a corner a bit harder than stock. Plus it keeps the car looking from like a monster truck but not so low you have to worry about scraping on everything, been down that route before on a different car and it wasnt fun having to scrape the sub frame over speed bumps.
