Each to their own with things like this. However...
I read somewhere that it was only ever Apex's and Straights/11 Spokes fitted to the MG V8 models, as these were the only wheel styles strong enough to safely handle the extra power/torque.
As both these designs have many spokes (hence directly spreading all the additional load around the body of the wheel), can you be sure your new ones will be strong enough, especially with just 5 spokes ?
I appreciate this is a somewhat simplistic way of looking at it, but could get interesting if you were to crack the centre from an aftermarket wheel
Good luck whatever you choose
