Hi all, I currently race a 2011 CRG Tork chassis in the LO206 class at my local track. The past couple of races I have noticed my kart has really fallen off in terms of front grip after about 5 laps. The kart feels great for the first 5 laps and has good turn in, however it develops a bad understeer. Any thoughts as to how to correct this?
Front wheels: all but 1 spacer out
Rear width 52″
Minimum caster/max camber setting
tire pressures 12 all around on hot 90 deg. day
tires: bridgestone YLC
1 seat strut on left side of seat
Front bar in and flat
Move weight from rear of seat to front under legs
move front wheels out final spacer
Increase rear width
I know the other answer should be increase caster, however I found that I got better exit speed when I took it out.
Valid question. When this first developed that was the first thing that I changed. So the tires only have 2 races on them since changing them did not fix it. As for the TP change, I think it has more to do with the rear’s being stuck to the track as compared to the front not getting enough grip, if that makes sense. Im willing to try some different TPs though.
Matt, what happens is the rear wheels heat up and get real grippy. They overpower the fronts, making a push. Give the front end more positive camber which makes the inside tire lift for a longer duration through the turn stopping the push. Works for us every time. Learned that from Mr Koyen.
