Chimaera/Griffith Estoril wheel centres

[RDV8]

Some advice please....smart new wheel centres arrived today,thought it would be a straightforward job replacing them. Have tried scraping/ hot air from hairdryer/swearing at them,but they really don't want to come off.

Am a bit wary of warping the plastic by using the hairdryer ....surely there's a better way ?

Thanks gents.

Took a bit of mixture of advice given....bored small hole with a screwdriver then prised it off. Brake cleaner to remove the old glue. Took 10 minutes.
Thanks guys.
