Lowering your vehicle provides several proven advantages in handling performance. Many enthusiasts, however, ignore the issue of disadvantageous suspension geometry changes resulting from a lower ride height.
Stock components allow slight changes from the stock, but they often are not able to properly align the car after the suspension has been modified. ECS Adjustable Rear Control Arms allow for over 8 degrees of adjustment. Street & track enthusiasts will appreciate this needed measure of adjustability.
