Thanks for the review.
Caps are emphasis, not yelling.
I worked at Dinan--known for the best no-compromise
aftermarket BMW suspension systems in North America. The important thing to consider when purchasing suspension parts is that they are part of a SYSTEM. None of them act in isolation. When Dinan, Eibach, or whoever designs and releases a suspension upgrade kit, those parts are tested by experts to work TOGETHER as a SYSTEM. Therefore, the best results are almost always when the whole kit (FR/RR bar, FR/RR springs) are installed. At Dinan, suspension tuning could take 3 months and involve 2-3 different bars and 5-6 different springs at each axle. This is what it took, along with an expert driver, to find the optimal package. Now, if one of us is willing to go to that length to test all the different parts--and is an expert driver--feel free to mix and match. If not, 99% of the time, it is best to use the
aftermarket company's FULL PACKAGE.
