Need help with overall rear end grip, kart is always loose on exit compared to front runners. The kart is not so bad on fast sweeping corners.
Most front runners are taller and heavier than me. My size front runners have their weight mounted on the top of their seat.
My total weight is 186kg, 16 kg on the left next to my seat and 12 kg at the front with 43% Front 57% rear
I’m 1.73 65kg
4 stroke 24hp
Class weight 185kg
Tire MG Orange/rental line/ very hard side wall tire
Front 1 1/2 spacers
Front bar in
Rear 1380
No seat struts
Seat at 630 mm can’t find anything on the mac seat position, otk recommends 625 -630
Top kart recommends 615-635
Neutral Caster lap time 50.7
Half Caster lap time 46.7
No adjustments change the situation.
Should I lift the seat and move it rearward?
Should I try seat struts?
Should I move the rest of the weight to the back top of my seat ?
That’s a very wide swing in lap times, there has to be another factor at play?
Top kart’s seat recommendation is just a starting point and probably not ideal for the hard tire you are running.
Something else is happening then, as a small caster adjustment (no adjustment for that matter) is not worth 4 seconds. It may be a driving issue or something fundamentally wrong with the kart.
The difference between nailing the setup and being way off is 0.5-1 second at MOST. 4 seconds swing is a sign of a different problem.
Before diving too far into suggestions for chassis changes, it would be worth considering if your driving is consistent, as any chassis setup changes will be completely worthless without first nailing down driving consistency or ironing out whatever other issues the kart is having that’s causing that swing.
