There is a lot of good advice being offered here. Personally, I like the BMR products as they are well built and have zerk fittings on them for lubing. I think this is important to prevent squeaking down the road. Another thing I would recommend is to do the shocks and dampers when you are doing the lowering springs. I was going to cheap out and use my stock shocks, however, advice from so many people on this forum telling me not to do that was the convincer. I am so glad I went with new shocks and dampers (Koni STR.Ts); the ride is awesome and the car handles so much better. Sam Strano knows what he is talking about so you can´t go wrong with his advice.
