Marc, When I picked up the car after the Dinan Stage 1 Suspension install I drove the local Santa Monica Mountain canyon roads, and the next day a run up the 33 and 58 Hwys (excellent local twisties). The new suspension has made a significant difference in how much better the car handles and feels and that is from the stock M3 set-up which was already very good. Your alignment work was spot on! The car just felt like it was on rails, and on straights I could take my hands off the steering almost forever and the car would not budge even a millimeter either to the left or right! I've had alignments performed by professional tire installers, but your work is the very best I've had done. Thanks Marc for providing an excellent product and highest quality professional installation and service! Robert R.
