i did this and couldnt be happier with my s550.
bought it in AZ and had it shipped to CA without ever seeing it in person. Obviously saw tons of pics and knew exactly what i wanted, and test drove diff models in CA before buying.
bmr toe rods, steeda subframe bushings, alignment kit, support braces, and transmission insert. oh and replaced the expanded o-rings on the UPR catch can..
thnx for the reply
didnt even think to try that tbh. ill go give it a try now. The dealership told me they had to order some electrical module or something that sits behind the dash and they'd call me when it came in
