Voodoo, here was my setup. I think we ran on the same track and series.
- 40wt oil with HPI 2 hole pistons
- HPI silver rear, Tamiya blue front springs
- medium roll bars front rear
- 3deg rear toe in
- followed the Hara setup
- negative steering expo and dual rate, depending on the grip
- I do not put tire sauce on the front
I think widening the rear lessens the side bite on that end and might worsen the situation. Try narrower rear or widen the front. See you this weekend, let's try to set it up. Or if you want to buy my car, even better
Good luck in Bangkok!
