If its relevantly cool inside, use the 20s but if its hotter inside, use the 24s.

28's in the front and 24's in the rear. If the traction is really low then you can try 24's in front and 20's in the rear, carefull though, you might traction roll.

HPI reds or the Xenon Grey's worked good for me this past winter

Foam will be faster the rubber .5 to 1 second a lap at least. )



As for pricing JACO and SMC now have a Vancouver based distributor so prices will be coming down soon

Speedmind foams are crutty compared to a jaco, but the TRC is way better then both if you ask me.

Foam is a lot faster then rubber in mod and 19, but its closer in stock where traction isnt as important.
