Sorry this is another one of my musing posts.

I suppose the lighter the wheels the less resistance, I'm sure a cleverer man than me knows the physics behind it but does the weight of your wheels affect handling, I assume it does but how much?

I notice the BMW e30 race guys use Team Dynamics Pro Race and they come in at a little over 6kg for the 15"

My Compomotive TH weigh 9kg each at 15"!!!

What are the preferred wheels of you track day guys?

The pro race are supposedly 9kg for the 17 inch wheel, you only have to look at the Compomotive TH to see where the weight is though im my opinion, but it is at least a strong and quality wheel

Alpina 16 inch wheels are only a little over 6kg for comparison
