Thanks guys. I was kind of replying to bishops view of the lack of support from top .. anyway..
I got my super clean.. but used photon today.. it currently has a gear diff in front and ball in the back. What's the benefit? I have read about rear gear diff and spools up front. But im not certain what setup does what.. last time I raced touring was a xray fk05 around 2006... lol its been a while. Good thing is I learned gear diffs a bit from racing 8thbut scale offload. But just not sure in TC.

There are lots of tuning options available with gear diffs. You just have to experiment and see what works for you. Thicker oil up front makes it closer to a spool, thicker oil in the rear slows the rotation of the car.

If you're testing the differences between a spool and gear diff in the front, I would leave the rear diff alone. If you change other parts of your setup, your test will be flawed. I would suggest using the ball diff in the rear while you test the front changes. After you've settled on the front drivetrain and the car is consistent, add the rear gear diff and start experimenting.

Nice mounts TeamWTF, I kind of wish TOP had done a carbon option mount, as much as I like the alloy, it's overpriced, bling city though.
On my Photon I'm still rocking a Micro/TOP front diff with 200k, and Yoko with the stock 700cst fill, I find it a very good combo (10.5T), though I keep meaning to up the oils in both ends, I find it a little light at times, depending on traction though.

You guys run foams right? We run rubber. Car feels pretty good at the moment.... Just trying to get more initial and less on power. Tried droop and springs so now for something a little different... Car is great to drive and still carries more speed than most.
I'm running almost kit setup with 2.5deg rear toe, 1.5deg+ front toe, Small roll changes, shock locations, ackerman all the way forward, and no sway bars.

Hey guys, just picked up a Photon (USA edition)...getting back into running 1/10th touring after doing years of 1/8th offroad.
Anyways, I'm looking to purchase a gear diff for the rear. I was thinking about getting the Spec R BD-5 diff but I heard it has leakage problems? I don't mind paying a bit more for the Yokomo diff if it doesn't leak at all. Just not sure who carries it around here.
What gearing do you guys recommend for non boosted 17.5? Any setup tips for both asphalt/carpet with rubber tires? (Will be running at Norcal Hobbies)

To everyone looking for carpet setups please at least try this one - http://racerlog.com/w/images/3/39/Ho...up_11-6-10.pdf
It is the basis for all carpet and asphalt setups that Larry and others have successfully run for the past 2+ years. The hardest part about this setup is building the shocks correctly. If you use Larry's method this setup is dialed. If you use EJ method for carpet with this setup it doesn't work as well. That said I used EJs method for asphalt racing as it requires less oil refilling to remove air from the shocks.
