I am wanting to order some drop springs. What springs are best? Ive looked around and it seems H&R are popular. Just curious has anyone tried the Megan Racing, Bav Auto or any other springs besides the H&R and Eibach? The Megan Racing springs ive seen for $119.99 and the Bav Autos are $225.00. Just looking for opinions please. I will be dropping an 05 530i with Miro 111's (20 x 9.5) all the way around.
