    hi all,

    in process of finally getting my M4 CP booked in for the MP HAS suspension upgrade kit

    spent ages trying to work out what drop as have MP front splitter and been measuring clearance over my local speed bumps and drive like a nutter :) reckon the BMW recommended drop heights of 633 front / 626 rear will be ok

    now got that out the way interested in peoples experiences of the upgrade, have you noticed much difference (for reference an running the 666m 20" wheels) ???

    thanks

    I believe it feels more planted and sturdy, but others would say otherwise.

    I think it’s all positive, the drop on the front will require a bit of thought in some circumstances.

    The only negative impact is a bit more road noise and a few clunks from the springs on slow speed manoeuvres, like reversing into a space etc. Not sure if everyone gets this or if it just mine.

    Mine on HAS kit, plus 763's and carbon tat, including splitter....(so far still attached - loads of room, just be a little calm over humps)
    I feel its a lot more steady and surefooted especially when pushing on a bit.

    Speed bumps in the road are not so much an issue, but things like the full width sleeping policeman, multi-storey car park ramps, coming off a garage forecourt onto a road with heavy camber etc.. those sort of things might just need considering and using a slightly angled approach or cautious approach. I am in an M3 and it is low at the front with the splitter:
