I've had the coilovers on the car for about 2-3 weeks and I've put 300-400 miles on them. Im happy! The ride is close to stock, however handling is a huge improvment. The car is more planted threw turns. I gave a ride to a friend who also has a 335i ( stock ) and he was amazed at how much better the car felt. The product is top notch, the customer service is ouststanding. I had tons of questions about set-up and i always received a reply, even got a phone call.
Theses coilovers have exceeded my expectations on build quality and performance.
