Have they moved Jay , I always thought they were in the Bridgewater area of Somerset when Tech-Del (?) were the parent company. Mind you in those days they were Magnesium alloy (not easy stuff to cast or machine , but very light) I guess they are now plain aluminium alloy?
I must admit I have been sorely tempted myself to invest in a set of 16 inch Minilites in order to be able to use the Toyo Proxes 205/55 x 16 tyres that everyone raves about.
Have you asked for them in body colour , I think that can look very smart.
They moved several years ago to Telford and yes, originally Tech-Del......they still may be! They still make comp wheels to special order in magnesium. Mine are in aluminium alloy though!
I've had them in body colour....black. Mean and moody 🤓
