I've kept my Plus Four badgeless. I prefer the cleaner look and was removing badges from the Plus8 I had previously. Too much clutter! Also interfering with airflow to the rad. The car had a Morgan aluminium rad but , in my view, only just capable of handling coolant temp. Seemed on the limit. No overheating but the fan kicked in a lot when in slow teaffic in summer.
Apparently PlusSix cars when raced would go into limp mode due to heat build up. Plus Four seems ok though.
I might put a couple of badges on the rear, possibly on the luggage rack.
