Sunday testday!
Just got back after some more testing.
Changed the rear rollbar to 1.4, which worked out great icw 5k diff oil.
Shock oil was the same because it was a hot day...
I changed the rear spring to Yatabe Orange, also much better.
I added more kickup but didn't work out for me.
Still looking for some more steering. Next time I will try YZ4 front arms and knuckles.
Overall quite happy with the improvements. Car was easy to drive, planted on high grip astro.
