At the risk of repeating an age old topic, I can't decide whether to replace the m-sport shocks on my clubsport with Bilstein B4 or B6 units. Any first hand impressions of either would be really useful.
I did read as much as I could on the topic but still can't decide. I understand the B4 is pretty much an OE replacement and that the B6 is a definite upgrade. Either will, or course, feel much better than the currently well worn out suspension. I will be replacing all the associated parts, not just the shocks.
So, will the B4 be good enough? Will the B6 ruin the ride? I'm not after a trackday car, but like a good handling car.
