I love my Sprint Springs, with Tokico HP Blues. The Sprint Springs provide a 2" drop if that's what your looking for. Anything higher, theres a lot of good aftermarket spring manufacturing companies, you just have to choose which one you like the best. I've had Eibach Pro Kit and Sportline, but sold them both, since my buddy works for Sprint. I tried Sprint and I love them. Eibachs are great springs, but I am happy with my choice. Try a Japanese manufactured spring, some are cheaper in price compared to Eibach's and are just as good. Did you know that the founder of Sprint Springs was a design engineer for Eibach and the founder of Goldline Springs was the same, but he was from Suspension Techniques.
There's so much to choose from now and you can't go wrong, especially with the technology today.
