ZUN Coilovers Suspension Lowering Kit For BMW 5 Series 2004-2010 Sedan RWD Adjustable Height 87625837

Why We Choose Twin-tube  Coilovers

1. It is easier to secure sufficient stroke, because the oil and gas chambers are separated and not positioned serially.
2. The use of base valve enables to keep gas pressure low, allowing for a more comfortable ride.
3. Low gas pressure avoids stress on seals and keeps friction low.
4. Compared to the inverted type, friction can be suppressed.
5. Even if the shell case is slightly damaged, the function of the shock absorber remains unaffected.
6. Superior manufacturing processes allow to keep production costs low.
