Probably a dum question this - but is there any down side to fitting a WALK onto a Mk5 GTI?
However in chats with my local tuner about a change of suspension, I'm thinking Bilstein B12, I asked about fitting WALK too and his thoughts are that it too falls into the general "engine mounts = harsh as hell" category. Which I really don't want. I really respect his view but wondered on other peoples thoughts.
With respect, I suggest your 'tuner' either has little experience with the Mk5 platform, or plainly hasn't got a clue about the WALK.
When fitted in isolation, the WALK will not make the car ride or feel any harsher than standard rear TCA mounts. As others have said, the only thing felt will be by the driver only - in the form of very slightly 'heavier' steering.
The WALK basically does two things: (a) improves the self-centering of the steering during forward motion (through an increase in castor), and (b) provides far greater control to the front roadwheel assemblies during harsh driving and/or road conditions (maintains geometery due to semi-solid nylon bushing).
I ran a Vibratechnics front mount years back on my old Mk2 GTi and never felt it 'harsh' but then a Mk2 on 195/50/15 is somewhat more 'comfy' than a Mk5 on 18" 40 section tyres. So I'm erring away from engine mounts per se, but would like to know if WALK does transfer vibes into the car and make it harder/more choppy for road use.
ALL areas of the Mk5 have come on in leaps and bounds compared to the Mk2 - not just engines or electronics, but also chassis dynamics and 'noise vibration and harshness'.
There are many of us on here with WALK, AND uprated engine mounts - and they are still perfectly refined enough to be a daily driver for peeps with knackered backs, SWMBOs, oldies, etc!
I appreciate it's a tricky thing to judge, but if anyone has fitted WALK and then compared the drive afterwards did it make the ride harsher and less compliant.
When I fitted my WALK - thats all I did, so I could try the 'before and after' drive soley on the WALK. It makes ZERO effect on the harshness or compliance of the ride.
I'm probably at the opposite end to RR in terms of wanting to hear and feel the engine working and the transmission doing it stuff. Really want to minimise harsh vibes through the car. So would just like people's views.
Get it fitted man, you'll wonder what all the fuss you are fretting over was about . . . honestly - you wont regret it.
