I'd definitely like more off-power steering so if I can loosen the front diff while staying within the acceptable range i'll try that, but since my diff and slipper combo is golden right now I may start with the extra washer. Seems that many of setups I have seen call for 30wt in the rear and the jumps in the current layout are really well designed with proper landings so I may try that as well.
BTW, not to jinx myself, but I am new to mod and new to 4wd buggy, and not a great driver by any stretch. This buggy has been very tough and reliable, and I guess I got a good batch of the ball cups because I have only busted one in 3 months of driving/racing on a weekly basis. Other than two broken arms and a torn front bumper that has been it.
To further expand on what rigor said and to add my own experience on the diffs to the mix:
You would be surprised at what constitutes tight/loose on diffs in this car. The most important thing you can do for your sanity is ensure that the front diff is always at least a bit tighter than the rear, or else the car will start to feel inconsistent, at least that's what happens to me.
My NORMAL front diff setting is like 1/8 to 1/32 turn off of tight with a 5/64 L wrench. My normal rear diff setting is 1/8 to 1/16 turn from tight. You can definitely get more rotation out of the car with loser diffs, and that is a VERY good and correct way to do it, but you will be giving up a little high speed stability with looser diffs. I find that the tighter the diffs are, the harder I can drive the car, or "wheel it" as some put it. If your track is super tight, loosening the diffs may be the perfect and correct answer, but do know this: you should be able to get a LOT of low speed steering from this car even with a reasonably tight front diff. IF you're on a lower traction track that is tight, then loosening the diffs is almost always right, but if you're on a higher traction track, you may want to look at other places primarily.
Only you will be able to know what is right. I just wanted to ensure you knew what constituted "tight" and "loose diffs" so you could determine where your diffs are already compared to others. I run 32.5 weight oil up front in my car and a tight diff. Gives me bananas steering in the sweeper and lots of low speed steering too.
Try it all and let us know what worked and what you liked!
