Are you seeking the ideal road balance for your everyday driving needs, or perhaps planning to take your car on the track? If so, the 5100 STREET PERFORMANCE TCO SUSPENSION is the perfect option for you. Maximize grip by controlling rebound and rideheight of your car. It includes camber adjustable front top mounts and springs. In this set front and rear dampers utilize a coilover design. By choosing this design you prioritize adjustability and the performance of your car. Coilovers which will offer more adjustability for both damping settings and ride height, and typically provide more consistent and predictable handling characteristics. The initial setup for setting and spring rates is rooted in our extensive development and testing process. Individual preferences can easily be fine-tuned by making adjustments to the rebound knob or altering the ride height. You can adjust the rebound, means you can control the return to extension of your dampers, enabling you to attain the ideal road balance tailored to your specific requirements. With 12 distinct positions to choose from, each adjustment delivers distinct feedback and a unique driving experience. This set of suspension also includes, where applicable, camber-adjustable front Top Mounts and solid rear Top Mounts. The camber adjustment will offer you more wheel adjustment and allow this geometry to be altered to transform front -end grip. AST Suspension is a monotube design. This is a benefit for you because these dampers offer a large piston to control the adjustability of rebound damping. There is no aeration or foaming in monotube dampers, this will result in a more responsive valving. AST high pressure dampers will increase performance, when you need it, in various driving conditions. These dampers are rebuildable, which means that if any damage or issues arise, you can have them addressed at a certified AST service center.Shipping Notes

Perfect fit and high quality.

Good product, not much to say. The product arrived quickly, looks to be of high quality construction, fit perfectly and took me only a couple of minutes to install. I love it when a product is no frills and delivers as advertised. I've used various filters from K&N before and have always had very good success with them so I will be buying more of these for sure when the time comes.
