Thing about that setup is that it wasnt used for that long from what I gather, and even the C arms are still in fairly good condition. The bilsteins have a lifetime warranty and I already have ball joints that would go into the control arms, I just never done it before and having a spare set is a plus.
And about the difference in the springs - the difference is only the specs, the springs themselves are just that - springs, they dont really go bad and they are both fairly popular and reputable companies (alpine and bilstein) I just wanted to know if anyone knows those specs. Cause the guy claims it will be almost a best handling E30 without coilovers.
