This company used to be called Performance Industries suppling Supalite wheels from Au.
I beleive Caterham dropped them due to delivery problems, and their 'minator' produced by K&N is their lookalike replacement. Although I think they are a bit heavier than the 4.8kg supalite
I understand the wheels are no longer cast in Au, but in the UK, this was changed to due to the unacceptable delivery time. My experience of the wheels since they have been cast in the Uk is that the quality is not as good. Apart from poor finish, I have had wheels where extraordinary amount of balance weights have been required, as well as porous castings. (Which are only discovered when you have paid for the tyre to be mounted)
It is fair to say however they were replaced......eventually.
13" Supalite wheels do clear AP 4 pot calipers, but you have to be careful where balance weights are positioned as they can foul the caliper.
If the quality are good, then they are VFM, I do however admit that I am considering new wheels, and supalites are not quite top of my list.
