ER SERIES COILOVER FOR BMW 3 SERIES E46 98-06

COILOVER TYPE:ER
SPRING RATE:10/10 KG/MM
This is the kit we recommend for the best balance of performance and comfort, designed by the factory to have the best overall compromise of spring rate, ride height range, top mount design and damping rate to suit the majority of car owners.

It is more than capable of dealing with fast road and track work but also retains a high degree ride civility so the car can still be used for mundane duties and long journeys without the ride becoming tiring.
