I am wanting to drop my car a little with some lowering springs. I am wanting to go with the eibach sportlines but some other brands out there are quite a bit cheaper. I searched and searched to try to find the consensus on the best brand but not finding a lot. Does it really matter or do some brands have issues? Any help is great. I just don't want to buy something that turns my car into riding like a washing machine or something thats going to have noise or what not. plus they have to work with my 235/40/18s
