any interest in the federal rs-r track day tyres?

Any idea on the weight difference, if it's not too much topic drift?

Weight difference between what and what? 6UL's in 15x8J are 5.6kg.

I dragged this off topic days ago. No one seems too interested in the offer of Federal 595RS-R's even though they're cracking tyres.

I meant between them and the standard wheels. Last time I looked into this it was hard to find out the weights of the different options. Often they were sold as "light weight" but no actual weight was quoted.

The ones in my price range at my local wheel specialist all seemed around the same weight, so I just went on looks and quality.

The standard wheels pretty good and light according THIS. The front 15"x6J's are 6.6kg and the 15"x6.5J rears are 6.9kg. It doesn't day what they weight of the 16"x7J but I guess saying  7.5kg wouldn't be far off.

Anyway, in comparison the the fronts you gain 2" in width and loose 1kg of weight which is pretty good.
