Wow !! Just came across this innovative product which gets fitted into any Car whether its Tata, Maruti, Hyundai, Honda, Chevrolet or in premium segment whether its Mercedes, BMW, Audi, Jaguar, Porsche etc I dont claim that this is a NEW PRODUCT but yes it is very useful one if you are facing Suspension Problems and getting lots of Jerks on Rough Roads and if your Car Suspension and Jumpers are Weak and you are not ready to PAY HEFTY amounts for its parts and labour. Then just for a very smaller amount you can say GOOD BYE to Jumpers and Suspension Kits by installing this " Car Coil Spring Buffers " between your Jumpers and can get a very smooth and Gliding effect :-) So get ready to face this new experience of Smiling with Driving :-) Note :- Experienced myself in my beast, BMW 3 Series and henceforth am that Confident with this Product.
