yes... you will get way more from a $300 school on crappy ruubber/wheels then you will ever get from having the ultimate tire. and driver improvement is forever. it never becomes obsolete or uncompetitive.
Even Drag racing is a skill. so identify what you want to do and give one of the instructors on this board a call. (Myself Loren etc) we can get you pointed in the right direction so your not spinning your wheels (pun intended)
