1st practice day on loose bumpy dirt went well. Running 6.5T motor. Started with kit setup except: no sway bar and left droop screws flush for max droop.
Tires: Holeshots in super soft front and rear. With open cell front and aka closed cell rear on tlr 22-4 wheels, Stock hexes.
Changes done in order:
- Ride height to 21 front to match 21 rear (same as my b64d) - not good. Nose high on jumps. Likes nose lower than rear. Back to 18mm front 21 rear.
- Reduced front toe out to 0.5 degree on each side vs. 1.5. Reduced front camber from -2 to -1. More stable but back end wanting to come around on power.
- Shortened wheelbase in rear. Moving both spacers to the back. A little more stable in the rear.
- changed rear toe to 2.5 (from 1.5). D block pills middle out on both sides. Again better still not great.
- Changed front diff oil from 15K to 10K and rear from 7K to 5K. Not as big of improvement as I expected but was better overall. Could drive harder without getting unstable in and out of turns.
- Added weight to rear with Protek stick on 5gram weights. 10gram I could feel the rear getting more settled and bouncing less over bumps. (Maintaining ride height with adjustments). Went to 25. Almost there. Went to 35 and was happy with the balance. Total rtr weight is now right at 1800g.
DAY 2 of testing. Only change was moving rear shocks to inside holes on arms. Helped with bumps.
In one day I was able to adjust the eb410 to be as fast as my b64d I have had all summer to tweak on. I still may try lighter rear shock oil as it isn't quite as stable over the bumps as the b64d with tall rear shocks and vrp valve pistons. |
