Customers say

Customers highly recommend our product, citing its excellent quality, usability and practical features which vastly improved the performance of their vehicles. Many praised its high value-for-money, superior to competitors. Notably, it saves significant machining time and upgrades over stock rubber bushings, enhancing the rear control arms' articulation. Some users reported improved handling, suspension, reduced lap times and more efficient wheeling after installation. The option to service and maintain the product was appreciated too. A repeated suggestion was to include grease zerks for preloading and lubricating the bearings.
