Each suction gap has a visible vacuum loss sensor

Quick eye ball when you get in n out is all it needs

You can prime any loss of suction via the built in pump in each unit

Total load can be held by just one cup

So I think your comments are assumption rude and inaccurate

That looks good.
I like warning if the suction pressure is not sorted.
You can still operate the roof with it on? (Obviously without the bag on it).

Any paint markings or dents from the suction cup?

i think this is great idea , i love the look of it ..... im planning some longer trips this year so this would be super handy, i would recommend PPF covering the top of the deck lid to avoid scratches etc.

So my experiences so far are…

The inbuilt pump and pressure warning is great and makes a precautionary check and re-pump if required easy.

Due to the complex shape of the boot lid you need to have a bit of slack in the screws that hold the suckers to the frame to accommodate the curves. Initially then remove any slack afterwards.

Need good polish level or PPF for a good seal..rear cup lost pressure over about 8 hours due to combination of slightly Matt finish of the boot paint in that area and cup alignment.

You are not allowed to keep it permanently mounted..I guess for paint reasons and to keep the cups in good condition. Can’t see any paint impact.

I’ll look for a waterproof bag that takes advantage of the surface area of the rack with a bit lower height.

I motored the roof with the bag attached just to see how it behaved but going forward I’ll adopt a procedure of mounting and unmounting the bag before operating the roof.

I can’t see other options that don’t either risk damaging paintwork edges or scuffing the lid if your preparation is not perfect..

Only downsides I can see (other than it kinda spoils the look of the car) is that your rear view mirror is null and void.
Personally I would rather just travel with less stuff.
But needs must.

I agree but you do have wing mirrors and/or travel faster.. :rofl:

It’s the 16 day trip two up to the Pyrenees in 10 hotels is the problem…not enough time to do any washing plus on the go most of the time..

You could take the Volvo XC70 and that would solve the luggage issue but….. :headbang: :headbang: :headbang:

After testing the rack bouncing around the Kyles of Bute I noticed one of the suction cups was losing pressure faster than the other two.

It never lost grip but I found it unsettling.

Chatting with the supplier we did various tricks like resting the rubber feet in boiling water for 30 seconds but to no avail.

In the end they sent a new cup which I've now fitted.

Also I adjusted the centre foot from its most rearward position on the rack to the forward postion.

This gives a more even fit and means the centre one is not trying to force the rack up on the other two feet.

I've ordered a pair of flatter bags to fit the rack too.

One thing I'm not happy about is, due to the curvature of the boot, the screws are held at angles and rely on overly large holes in the tubing to accomodate the curvature.

Not sure how to solve it..but I'm working on it.

What about filling the fixing hole with a cylindrical plug that has the fixing hole at the appropriate angle?

Ron that would be possible, it would need the holes to be widened out further initially..I'll think about it thnx :thumbsup:

As commander I’d be authorised to do whatever was necessary for the safety of the crew (me).

So I’d just motor the roof end off… :thumbsup:

Out of interest I’ve motored the roof with the rack loaded with twice it’s rated load.

No obvious issues…I’d guess if I did it 100s of times maybe there would be an issue..

But force majeure dictates … :thumbsup:

Morning, B21.

Have you put the rack on back to front for a purpose?

Good morning to you sir as well :thumbsup:

The rack can be mounted either way round..the recommendation from the supplier was to mount it with the hoop closer to the seats..most of the pictures of E89s show it that way ..here is a snippet of the said conversation….



Hi Peter

Sorry to hear about your issues/concerns this is not common. Never had the feedback re a spacer before. We have 30mm ones ?

Most E89 customers seem to mount it with the hoop near the cabin, as per attached have you tried it that way ?

1. Leave the screws very loose push down lightly above the cup on the frame to compress it a little and pump then tighten, they are designed to rotate to curve to the boot lid as you say.

2. The cups are certified to hold vacuum for 6 hours so 6-8 is normal. You would not drive for more than 2-3 hours so as per the instructions when you stop take a look and re pump if needed. They can hold 10-12 no problem as you say its all about the fit and making sure the surface is damp as this seals the microscopic undulations in the paint surface and provides a better seal. I suspect the 6-8 hour cup has a small leak in the edge compared to other two. The atmosphere is constantly trying to undo the cups.

Instructions re-attached.

We have been manufacturing and selling these for 6 years with thousands sold globally and lots of happy E89 customers, just take a bit of time and care fitting it and it will serve you well for years.

See

Hope that helps re-assure anything else do email me.

THought I'd post an update on the suction mounted rack and associated luggage.

After 2,700 miles over all sorts of twists, turns, bumps and occasional very high speeds I'm pleased and relieved at how everything worked.

The big breakthrough was finding some lightweight cabin luggage that was equipped with straps for holding items externally to the bag..these straps made it very easy to secure the bags to the racks without additional straps..

Later I realised if I cross strapped the bags it would the secure them laterally very well.

A good point was that it was pretty quick and easy to remove the bags and dismount the rack and store them all in the passenger footwell and seat if you you were parked up and concerned about security.

There is obviously a centre blind spot but the wing mirrors were clear..had a shock when lookig over my shoulder to see something big and yellow very close..kept thinking it was another car in my blind spot!

Turns out the same sucker system is used to hold push bikes on roof racks..so providing you follow the advice all seems ok.

The extra 40-50 litres of space, which is easily carried and managed should allow almost any long distance mission in an E89 for 2 people, roof down all the way!
