Ride height query

[mustdash]

Qucik query - I have coilovers fitted (put on by the previous owner) and it looks to be sitting very low at the rear - the coilovers have been checked all round and they are all at the same height, but the top of the rear tyres are sitting in the wheel arch (as if it's fully laden, even though it's not, if that makes sense). Does anyone know what the standard gap between the tyre and wheel arch should be? I can't seem to find anything on line....
