Ok, so i'm new at this. My brother knows a lot more then me about syclone's and all these cars. but i just bought me a syclone and had like a whole bunch of ppl look at it to make sure it was in nice and good shape needs some paint and stuff but. i was wondering is it bad to spin the rear tires(only) in like a brake stand building up the boost? Becuase i saw someoen do it and i didn't think that was good.Also is it bad to like build up the boost and then just stop building it up without using it? Thanks for the help guys. I'm sure you all know more then me soo far
