Guys the springs are definately made in germany. Most of the beemers, mercs audis and top getman cars use them. Yes the are TRD springs. TRD rebadged them. For 650 installed i gaurantee that they will ride better than king springs by far. Kings are a very generic spring (I have used them before). The drop was 30mm and 35 on the front. It looks sweet. Not too low at all. Prob not low enough for a lot of you but from going from a car that was too low to this it was heaven. The ride is the same. U can fly over traintracks and u can still go over speed humps. FYI the springs just went up in cost. From 550 to 600. Worth every penny.
