Question KONI FSD/Eibach vs. KW Street Comfort Coils

Which is going to give me the smoothest (least jarring) ride on a 2007 335i Sedan with Sport (keeping in mind that the KW's are almost double the cost)???

Koni FSD + Eibachs will keep the ride as close to stock as you can but come alive in the corners.

Er, I guess I wasn't quite clear in my question... I'm looking for a SMOOTHER ride than my stock Sport Suspension.

Couldn't have said it better. The FSD setup will ride smoother but the Coils will offer better performance.

That will be tough to achieve, you can try trading someone with non-sport if you want smoother. Also make sure to remove the stock run flats, that contributes significantly to the stiff ride.

i've had both setups, as well as kw v1's....

your best bet is to stick with the stock springs - perhaps replace the factory dampers with FSD's and replace the run flat tires..

+1 to what Nick said. Ditching the runflats has a dramatic effect on ride quality

I have the KW Street Comforts and they absolutely ride smoother than the stock sport suspension, even when they're not on the softest damping setting. They also make the car corner flatter and keep the wheels on the ground better when you go over bumps - especially when accelerating. I've had mine on for about 5 or 6 months and love them. I have no experience with the Koni/Eibach combo so I can't say which is smoother, but I can say for sure that the KW SCs are smoother than the stock sport setup. And BTW - **********s beat everyone else's prices as per their lowest price guarantee. Hope this helps (at least give you one side of the equation) and best of luck with your decision!

FSD's and stock sport springs will give you a smoother ride then you have now.

From what ive heard the koni/pro kit and non run-flat tires will be more comfortable than the stock sport setup
