Did mine too earlier this year, fantastic job, however a couple of points:
Remove battery connections before tackling
The main bolt will be a sod to shift
Watch the airbag connector on the wheel, it has a small yellow plastic clip that needs to be pulled out to remove and must be pushed back in place when refitting
If you go for an exchange, be prepared that the new wheel may be just off centre if my experience is anything to go by. Will need track rod ends tweaking
I’m sure Bettabuilder will be along soon and post, he had the flat bottom wheel design, if not drop him a PM.
As above, battery disconnection required, 2 10mm bolts hold the centre of the wheel on (airbag/horn push) these fasten at the rear of the wheel cowl hidden under 2 rubber grommets. Once removed you will see connectcon for air bag and SW controls, remove clip for airbag connection.
To remove the actual wheel you’ll need a suitable size socket and bar and maybe a sharp blow on it to release the nut. Do not remove the nut fully leave it on the column spline then you’ll be able wriggle the wheel at the sides which should relaese it from the spline. Leaving the nut on stops you jerking the wheel upwards and smashing you teeth out.
Anyway, RSW (Jack) did a fantastic job for me the addition if a flat bottom to the wheel was £50, I also made the trip to his works for him to fit for £15 ( I bottled out of doing it myself ) all in was £215 IIRC, flat bottom, thicker rim, thumb grips, perforated and smooth leather and the 12 o’ clock red band, fitting. Worth noting, the flat bottom is more of an illusion? Top to bottom and side to side measurements are equal but look different. I absolutely loved that wheel and it’s on my list for the new car to have the same treatment.
He’s away at the moment until the 24th April, otherwise I would have had it ordered already! I think this time, I’ll have a go myself and will pay the refundable wheel deposit option.
Had mine done by Royal and am well happy with it. I had them fit a replacement and found it to be off centre but the next stop was a four wheel alignment so was no problem. Cost was about £150 if I remember correctly/
