Gear diffs in Touring Cars.

gear diffs react differently than ball diffs. Its my understanding though that a ball diff is quicker through the corners as they rotate a little better but the gear diffs are faster coming out of the corners as they tend to slip less with sudden bursts of power.
Everybody has a different preferance. I've done well with the gear diffs in my 1/10th offroad cars but a lot of people say the ball diffs still feal better to them. I dont think one is really better than the other I think its just the difference of how you drive and how you like the car to feel.
Hope this helps some but I'd say a gear diff could be a useful tuneing aid and if you could afford it it would probobly be a good investment to have in your spares box. Just like a one-way, there not good in all situations but sometimes its just what you need

If a gear diff is well build you have less maintenance.
Also no slip at all.
Bad thing is that if you want to adjust something, you need to remove the whole diff and put another type of oil in the gear diff as to a ball diff just adjust the tension.
Bad thing of a ball diff is that they are more prone to dirt and need to be rebuild more.
Either way you have pro's and con's on both diff's.
Did run them back to back in the same car with same setup and did have a faster lap time witht he gear diff(hometrack).
At another track it was just the other wat around.
Better laptimes with the ball diff.
It is a good investment and it could ad in getting lower laptimes.

you should look at it as a different tuning option, but having gear in mine and working very well, then depending on track condition, I can go back to ball if needed

I have no doubt that the gear diff will be equal to or better than a ball diff in all conditions. But the gear diff is relatively new so it makes sense to go back to the ball diff when in doubt about gear diff tuning. Once more people run the gear diff and learn to tune with it in different conditions it will no longer be a tuning option - it will be what is used all the time.

When you guys are talking about gear diffs, is that both front and rear ? What combo is the fastest for you:
GEAR DIFF(G), BALL DIFF(B), SPOOL(S) :
FRONT REAR
#1 G G
#2 G B
#3 S G
#4 S B
#5 B B
I only run #4 in my tc4's with zero maintenance in 6years !

I remeber racing touring cars on carpet back in the mid to late 90's and we all had cars like the HPI pro and ofna's , shumacher sst 99's ...well anyway ,there was a guy that had a hpi sport with two gear diffs and a fiberglass chassis......and he would always wipe the floor with most of the racers there. It was unreal. So I think it has to do with the driver and how he is used to driving his car.

Did that guy ever race you guys on asphalt ? Most racers seem to run #1 with different weight oil, but has anyone tried #2 or #3 ???

I'm thinking of trying #3 for my 17.5 blinky tc that I'm putting together, but it may be a bit before that comes about, money and all. I like the thought of low maintenance once I find the right oil for the gear diff.
Currently I'm running #5 in my TC4 VTA. I have tried #4 in the VTA didn't like the chatter and in turn the over heating of the front tires. I'm going to give #4 a try again here shortly since I just got a set of losi lcds to help with the chatter.
