On track 4x4 HMBCift kit

[CamJam]

Hi gents,

I owm a s4 2018 Ti. I would like to install the ontrack 4x4 HMBC lift kit so i can fit a OL tripple loop bullar and not have it sitting or hitting the bump stops. I'd love some help and feed back from anyone with personal experience of installing this kit.

My questions;

How does the kit stand up over long trips on fast corogated terrain?
Does the kit cause any long term reliability issues to the suspension and the hydraulic system itself?
Does the kit cause premature tyre wear?

Sorry for all the questions but im struggling to find clear answers to the above questions and im weighing up whether im better off possibly not having a bullbar altogether.

Thanks in advanve gentleman.

I am going through this right now, with the same car. I HAVE booked in at the end of this month for the TJM Explorer (single hoop) bar on the front, with recovery hooks, lights and an aerial to go on it as well as the 2" lift.

From what I can see online, if you don't get the lift, it only sags around 10mm - OnTrack also suggested this. So I am now thinking about not getting the lift done, and seeing how it goes. Regarding the bump stops that people keeps talking about, well - it's within the 85kg limit (I am not getting a winch) so it's within its design specs to be able to handle the bar up the front, with the recovery hooks (which I am guessing are about 20kgs all up). I'm like you though - very undecided. I will be getting a bar though, mostly for the protection but partly also for the fact I will be driving at night and want good lamps up front (not behind the grill or with an LED Bar) and to mount the aerial.

OnTrack also advised that with the 200+ lift's they've done, a percentage (they mentioned maybe a dozen) had issues with the CV boots. This can be remedied by putting on different boots they have - but it costs around $600. For me, that's a 5% fail rate, and to be honest it scares me a little. I get that I can fix it if it becomes an issue - but I don't do beach, I do remote travelling which is the last place I want a CV failing.

What I really want are just replacement springs for the front that are just a little stiffer in order to maintain the height - but OnTrack has said they can't do that, although it beats me why (perhaps the Y62 uses some specific ones that only come with that larger lift if required).

At the end of the day, I don't need a lift. But like you, the idea of bump-stopping along outback tracks has me, at this stage, leaning towards getting the lift. I think I need to call them again just to have the conversation... perhaps I'll not get the lift and then later go and do it if I need a Rear Bar or similar (if you get a rear bar later, it's a different set of springs they need to install).
