I still haven't seen quantitative results on any of these kits that show the benefits. The benefits are always sold as "better", "chromoly", "coilovers"...yea yea.
Performance results? Kinematic improvement references [bump steer, camber curve, rollcenter migration, roll center changes, etc.]? How about manufacturing, what do the welding fixtures for these look like? How is the quality and accuracy checked before it is sent out?....Nada, they're sold on the premise that they are expensive and use coilovers so that
must be better..
Hence why I just put Hotchkis parts on my car and am moving forward.
