I have owned a 2002 M3 E46 Coupe, stick for 3 years. It came with Tein lowering springs...stock shocks and struts and I hate them...Ride sucks and way too low. I have found a ZCP suspension from a 2006, low mileage car. Does anybody know if it is compatible and if it lowers the car below stock. Thanks.
I would recommend going with a fresh and new setup all together. Suspension makes a huge impact on the handling and it is risky to play with used components. My 2 cents.
