Hello Racers!
During our recent testing in preparation for Reedy Race, team driver Reno Savoya got all of our 22-4 2.0s' way more dialed in with an outside the box setup idea. After showing us how good it was with his speed on the track while running at Travis Brock's SDRC Raceway, Dakotah and I both gave it a try and we instantly knew it was an improvement for the car - and pretty much the rest of the team switched over during the Reedy Race. What was this magical setup change... glad you should ask!
We've found that running a ball diff in the rear, paired with a gear diff in the front, was a great way to maximize how the car drives. The gear diff in the front allows the diff to 'free up' off power to help the car turn in and rotate quicker, then 'lock up' on power to pull the front end out of the turns. The ball diff in the rear, gives the 22-4 the stability, consistency, and predictability of a ball diff setup. Really, the front gear diff and rear ball diff setup gives you the best of both worlds, without the negatives of either. Even the ball diff life-span in the rear is improved with the gear diff up front.
So here are some details we 'fine-tuned' after making this change. With the ball diff adding consistency in the rear, we found that we could run the front diff with thinner oil to improve steering. We're pretty much all running 30,000cs oil in the front diff, so I'd suggest starting here. If you want a little less aggressive steering, try moving up to 40,000cs. For the ball diff, we've been running it set very similar to a 2wd 'normal' diff setting, about 1 full rotation. We have found that running the diff too tight can make the rear feel a little less consistent, almost like a solid axle.
If you have the 22-4 2.0, you'll need the parts listed below to try the ball diff setup in the rear:
1x TLR232017 Outdrive Set: 22-4
1x TLR232026 Diff Service Kit, Tungsten Balls: 22-4
1x TLR237000 5x8x2.5mm Bearings (2)
2x The black bearing spacers that come with the 22-4 2.0 kits, in the tuning parts bag*
* These can also be found in TLR231043 and TLR231044
Give this setup a shot, we're confident you'll like it!
Race on!
