As a newbie I’ve been very grateful for much excellent advice on multiple topics for which have been of immense use.
On hydragas replacement I’ve looked but don’t see any similar advice.
We know the 368mm ride height measurement (temp correction aside). However can I suggest that rather than guess the centre of the wheel, using the upper lip of the MG badge hub as a reference point. guessing the centre point introduces unnecessary error. Simply subtract the badge radius i.e. half the diameter. Also the height is a vertical measurement to the wheel arch, not at an off vertical angle as I’ve seen in some pictures/videos.
To anybody near PL15 - I have a Kennedy pump you can use here.

Re: Hydragas
In my humble opinion that's shared by one very respected MG mechanic down here ( not a dealer though ) it's not that much of an exact measurement.
Yes you can measure it to the last millimeter, but 368 at the front looks a bit odd to me, like a monster truck that shrunk.
This mechanic ( actually a panel beater by trade ) I mentioned never uses a ruler, he just pumped them up until the car 'looked nice' .
Customers were happy, cars drove nicely, and they came back for another service next year.
So if your car is above 350/355 mm and it drives well then be happy and fix something else
As ever, this advice is my own opinion and I expect others will disagree.
And surely we should be saying 14-1/2 inches !!!!

Re: Hydragas
The height correction is only relevant if the hydragas spheres are in good order and haven't lost their nitrogen. If the spheres have gone (and they usually have by 15-20 years) then any amount of pumping won't make a difference to ride quality.
