Suspension is a very interesting subject, and it's sometimes difficult to make informed judgments based on any recommendations unless you have experienced a given setup for yourself. For example, you'll get B14 fans (of which I am very recently converted to being one) recommending them, you'll get others recommending any of the cheaper options that offer a similar drop and you'll get others suggesting sport shocks matched to lower springs. There will be other options too, but in all honesty, unless you've driven the setup yourself, it's really difficult to make a judgement. It's really hard to truly know which is best for you.
Everyone's opinion of handling, comfort, ride quality etc is very subjective; what is sublime to some would be soft and wallowing to others, what would be firm, responsive, but refined to some would be harsh and unforgiving to others.
For what it's worth though, my B14s have exceeded my expectations, I went to
@BognorMotors for mine and was able to test drive 2 different B14 equipped vans to understand if it would meet what I wanted from my suspension before I spent my money. That was really important for me. After reading about the Solows and discussing it with
@T6180 and Andy at THQ I almost pulled the trigger on those. In the end it came down to being able to test the B14s before making my purchase, and the fact that the B14s fitted, including wheel alignment, was less that the cost to simply purchase the solow. The reason I didn't choose any of the lower cost coilover options is that I drive 30000 miles a year and need to be able to convince myself that I'm buying quality. I'm well aware that more expensive doesn't necessarily mean better quality, but I just can't get my head around how a company can design, develop, test, bring to market and sell a set of high quality coilovers that will last the test of time for less than £300, or even £500 for that matter. There are many people who have them fitted and would argue with that and perhaps I'm wrong, it wouldn't be the first time!
Whatever you choose, let us all know what you think once you've got them.
