OK did some high grip track testing. Wanted to check out the on power understeer for myself
Well first up, need to get rid of droop. I went +3 +6 in the end and that seemed pretty good. This was at a ride height of 4mm and with 57/60mm front and rear tires.
Remember I was running the kit stock setup here as a baseline.
Next thing, front swaybar is way too soft flat. Needed to go to 45 degrees on the bar, balanced it up using the gold rear and sliding the adjuster up 7mm.
Then I went to the Light blue springs front and rear.
At this point car was OK getting around the track at an OK pace, but there it was, the on power understeer. Also punch was quite low.
So I took my own advice and went with 50K wt rear diff oil (I prepped a 30K and 50K diff before I went) non LSD. While I had the car stripped down I went with the #12 ackerman steering.
Well all I can say is you gotta try it out for yourself
