LOL Pro Kart
How many big races has Pro kart won in the SE?
1 outta how many top chassis builders?
Ive used jack bolt on the front, make 1 turn in direction, make 1 turn in the opposite direction and it doesnt go back to where it was before the turn, thats why every MAJOR chassis manufacturer has or never has used them
Ease up there big fellow.
Where is the "major" chassis manufacturer that sponsored you for all those years now?
Not a shot, just a question.
FWIW, I still offer weight jack spindles on our chassis (have since 1993) and run them on AJs karts every weekend.
Plenty of "major" manufacturers have experimented with them (back as early as the mid '90s to my knowledge.)
The real reason not to use them is that they are simply much more time intensive to build, (time is money to a manufacturer,) which makes them costlier to replace (not desirable for rough kart racing.) They are also illegal (WKA) to be adjusted while the kart is in motion.
