Lightest weight track wheels

[Tracked Emira]

Someone mentioned these wheels on an older post, but they are very expensive, but very light.
Deciding on whether to get 18's in the front and 19's on the back. If someone figures out how to remove the parking brake then it would be 18's all around to choose from a wider selection of slicks. I want the Forged Magnesium wheels and I'm hoping someone here has a source that can copy and make these in the sizes and offset I will want. There are very few wheel companies that make forged magnesium wheels. If not, there are other levels less expensive, but are not as light. Help me make a decision

So in UK money about a ten grand. Ouch !!
Would love a set, but no way I could justify that expense. I'd be better off spending less than that on driver training
