I went B16 damptronic in the end. Miles better although share your concern that Sport+ is too firm for road use
Anyone know how you adjust the height of them - they come with a strange looking spanner... I think you can adjust the fronts in situ but the rears need to be pulled out to adjust ( that's what the fitter from DT said ).
And don't bother with the fitting instructions as they are worse than what IKEA dish out!!!
