Those are the tyres that I run at the moment indoors on carpet, because our club does not allow additive. Also, with lots of people running the minipins the top layer of the carpet has become all fluffy and bascially those are the only tyres that work.
Didn't know BMI did a purple chassis, but when I bought the chassis I was looking for a SSG one, so I could have had a BMI one instead of the PRP one, but when I saw the PRP one I thought it looked so much more practical and I love the idea of the side plates, so that's why I went for it and I have no regrets.

) and email then I'm sure they will order them in for you and ship them worldwide to you.
