Do kart specific spindles matter? Example... Local shop has a 13 degree rf spindle... My kart (excentrik) uses a 10 degree. What challenges would I face going to 13? Obviously, I can probably just order a 10 replacement (most likely will)... But in a pinch, what would the ramifications of going to a different degree spindle cause for the kart? Naturally, the kart would be rescaled and setup according to prior numbers.... But does it matter? Thanks in advance!
