Had an interesting chat today with my local Mini dealer regarding the F56 / JCW Pro Tuning Upgrade.
Apparently stock now in UK (100+units shown available) but at present dealers can not order.
Price quoted to me for the kit (Exhaust / ECU re program and I think air filter mod) was £1,600 inc vat with labour (un quoted) as an additional cost.
Also in addition you will require the exhaust tips (Chrome £80 each tip / Carbon Fibre £192 each tip - asked them to check as that seems expensive and wonder if this is in fact priced as a pair!).
Part number quoted for the kit was 11122359628
