This MTS Technik kit is assembled with main springs manufactured by EIBACH and developed in 3 versions (Street, Comfort and Sport). The springs in this Street Series kit strike the perfect balance between comfort and sportiness.

These shock absorbers are twin-tube gas-hydraulic versions. Pressurized gas acts directly on the hydraulic fluid, eliminating the "foaming" effect of oil (an undesirable phenomenon typical of oil dampers), for maximum efficiency.
Their setting is fixed and not adjustable for hardness (the factory setting at MTS is firm, giving it a real sporty feel).
Height adjustment is independent of spring preload, and therefore does not interfere with spring characteristics. This ensures high-performance damping in all circumstances, right down to the lowest setting.
Adjustable cup springs enable custom camber adjustment.
shock absorber bodies are galvanized for corrosion resistance and longevity.

INFORMATION: the original front struts will need to be modified for installation (installation manual supplied). Depending on the lowering value adopted and the type of rims used, spacers may need to be fitted.

This kit comes with a 2-year manufacturer's warranty with no mileage limit.

Give your E21 the very best, with a top-quality MTS TECHNIK kit!
