ACE is pretty much the main reason to own a D2 IMO. Getting rid of it is just a waste 
Did, not will
Belt wrap on the pas pulley is minimal, can see that being fun if it gets wet, there is a good reason the original belt wrap was large and the pulley was grooved.
Also note the back of the belt is suffering from wear.
As soon as he said you do not need a/c in the UK I thought plonker.

Hi folks.
Recently did an ACE delete and I'm happy with the results, so here's my tuppence-worth...
1st problem with ACE 2 years ago: blown seal on front ram. MOT failure. £100 to repair.
2nd problem 1 year ago: bearing gone in pump. Used pump off eBay £100.
3rd problem with ACE earlier this year: Red ACE warning. Many codes. Actuator faulty.
Pulling it out to attempt repair means disconnecting pipework and that's a nightmare. Replacement actuator can be up to £1000.
So, time for ACE to go.
I didn't really want to bin the ACE because I'd always felt it improves the on-road performance but that turned out to not be the case.
Thing is, if you're still running standard 29" wheels/tyres on your D2 they're good for on-road handling and they'll work well with ACE.
If you've fitted bigger wheels/tyres, they're going to flex and, as a result, you're going to get body-roll regardless of whether you've got ACE or not.
My tyres are very slightly larger than OEM (265/60/R18) and that was enough to render ACE redundant.
The less obvious consideration is what impact the removal of ACE has on OFF-road performance.
ACE gives the D2 ARBs on-road but also allows the ARBs to be automatically "disconnected" when off-road, for better axle articulation.
So, if you cover a lot of road miles in your D2 AND you do some serious off-roading you might think that ACE is useful but, as above, if you've got bigger tyres then it's not going to be much use anyway.
If, perhaps, you do a lot of road miles on OEM wheels/tyres and then bung different wheels on when you go off-roading then maybe ACE will still be useful.
Personally, My D2 gets used on rural roads and it's built as a lightweight weekend-camper so serious off-roading isn't a concern.
If I do ever find myself wishing I had better axle articulation (due to the normal ARBs) I can just spend £50 on a set of disconnectable drop-links.

Hi. I'm not a fan of ACE removal but i'll not comment your own experience though i must comment on this
without trying to initiate an off topic argument i'd say that "very slightly larger" should not be more than 3%(from std 255/55/18), anything above 5% difference in tyre circumference(5.1% in your case) is above the limit for all the system's(especialaly ABS) normal behaaviour, engine management included... fit an EGT gauge if you don't believe me... i'll not reiterate what i've already said many times on this subject.
