I've still got room to come in a few mm by machining either the wheel or disc bell.
At the moment with the arches hammered if I jack it up hard on the bump stop it just clears, there is a 225 width RSR tyre available, but it's a 45 series and might cause other issues being taller.
I'll make good all the damage done and wait until the beam has been set up before doing any machining.
