    I had fk ak street coilovers fitted on my a3 and the ride is horribly bouncy especially on the motorway any advice on what I should do to remedy this without getting new coilovers or refitting my sline suspension

    How low do you have them set?

    At the moment the distance between the bottom of the arch to the centre of the wheel is 12.5cm all around and I have 25mm of thread left to wind down

    Do you know how much lower you are running than standard?

    When I had some Bilstein coilovers fitted on a Leon Cupra R some years back they took some time to bed in and settle so after about a 1000 miles they were more compliant than in the first few days after fitting.

    Also, remember that the lower you go the worse/bouncier the ride will become, as there is less travel in the springs to absorb shocks and bumps.

    Unfortunately not it is an SLine if that helps at all I'm guessing probably around 80mm lower than standard so 60mm lower than s-line

    Then there is your answer. Surely that's got to be way too low to expect any ride quality. I think the S-Line and S3 are same ride height. I wouldn't lower an S3 more than 20mm to retain some ride quality, so yours must be very low.

    Do you have to use shortened bump stops to run that ride height?

    I used whatever was provided by the coilover manufacturer I am not 100% sure, in your opinion would I be better off running lowering springs and the sline shocks?

    Coils should be fine, but adjust them to raise the ride height.

    They're never going to ride like a spring / damper set up but then that's not why someone buys coilovers, its for the ride height adjustability.

    I'm not sure how yours will adjust ride height, so you will need to refer to your instructions.
