    Hi

    I am looking at changing my shocks and springs can anyone suggest a new setup, i would not want to change from the current ride height as my model apparently has M Sports Suspension package although despite checks i cannot confirm this...

    Bilstein kit or something else???

    What are you looking for then, i.e. what's the motivation to change it? There are some fantastic kits out there, it depends on your budget. Bilstein stuff is excellent the more you pay. Coilovers are extreme - but height adjustable. It depends on what your remit is - ride height, comfort, price, longevity...

    Well the cars done 115k and the handling is getting worse, tramlining like a pig, drifting, tire wear - so the tracking needs sorting out. I replaced the front rear bushes a few months ago and the drop links - which firmed it up nicely.

    The front of the car now feels loose - so before i pay for re-alignment and new tyres/alloys/steering arms I may aswell replace the shocks/springs and top mounts.

    So Eibach springs seem to be high on the list - FSD's? well im an engineer by trade so i will treat those with caution - i think i would have to go with Bilstein's. I just want to hear from those with M Sport setups that found a good replacement.

    And money is no issue

    You're right not to start by getting it aligned - that should be the last thing you do - here's why: when new, the car was perfect everything was aligned, and the bushes were tight. Now (as you mention tramlining) everything is worn, the suspension sits a mm or 2 away from where it should. Getting it aligned won't cure tramlining, it'll only adjust the geometry to suit where the car sits when they align it, and the car may even handle unpredictably afterwards. Address what caused the alignment to be out first rather than the alignment itself. Hope that makes sense.

    Anyhow, the things that wear at the front are (mostly):
    FCAB's (front control arm bushes), also called the wishbone rear bush / lollipop bush - they're 66mm on your car. When they wear out, they will make the front end loose as hell.
    Track rod ends - both inner & outer ones.
    Steering rack - they also wear & will induce play
    Steering column joints - there are 2 & a fat rubber guibo shock-absorbing disc thing, all of which can wear.

    At the rear:
    RTAB's - Rear Trailing Arm Bushes - they control the direction of the rear wheels.

    General:
    Worn shocks, worn tyres, underinflated tyres can affect handling - as can broken springs, missing spring mounts, worn shock mounts.

    There are bits & bobs to check there, some easy (like the steering & the FCAB's). So if you're thinking about springs & shocks anyhow (personally I'd only do the shocks & all the mounts) it's a good time to do it.

    What wheels & tyres are you running? Staggered wheels (particularly the 18in MV2 alloys shod with 255/35-18 tyres) need a robust suspension set-up. Any wear, particularly in FCAB's & RTAB's, & it'll tramline like mad.

    Finally, if you check everything out & renew what you can, and you still have some tramlining, look at the brand of tyres, and whether or not they're a matching set (i.e. make & pattern) all round.
