My take on this is no matter what you do you're never going to get all the air outta the shock. TLR's X-rings and machined internals are really good so there is not much friction, especially when brand new. With both of these factors, the shock shaft is going contract back into the shock body some. Nothing really you can do about it. The main thing is to get the rebound right in my opinion.

84/26 is way under geared for 13.5, I'm guessing you meant 78/26? You really can't gear the car properly for 13.5 with the 84t spur, there isn't enough room to fit a big enough pinion.

Gearing for temps is old school. The current motors are all running quite cool. The trick here is not always gearing for top speed but corner speed. some ESC's like the Tekin have data logging that help you see where you are topping out in RPM's and help you adjust your gearing. I agree with Frank with my Tekin Gen 3 RPM 17.5 I was at his same gearing after a lot of testing in 2wd. I have not tried 13.5 4wd but it sounds like fun.

I ran 78/27 at Hot Rod and my buggy was by far the fastest on the track. This is with a R1wurks 13.5 timing at 28 and a R1wurks fan beside it wired directly to the battery. I tried 84 spur at first and you can get it to work but it just creates alot of heat for the R1 motor anyway and you don't have the mid range. The rest of the car was stock even the bearings and all. The only thing I did change was the rear belt tension to C forward. It was a missle and super easy to drive. TQ and win. motor never hit above 150 in the outside heat as well.

It will always depend on which motor you have and how you choose to set it up.

very true, I can't speak for other motors but the R1 V7 has 30 built into it like the old ballistics so technically it is 58 degrees. 84/26 is a 7.43 FDR with a 20.3 rollout, 78/27 is a 6.64 FDR with a 22.71 rollout. In stock thats a pretty big jump. I have tried 84/28 and it was ok with that motor but it when I went to the 78/26 to 27 it really felt better overall. And its alot easier to get the mesh correct, with the bigger spur it pushes the motor all the way back to the belt cover and allows no air flow.
Its all personal prefrence I guess but I did some testing the weekend before and I don't think my car could have been better. I honestly believe this car with the belts is hands down the best car for 13.5, mine was way heavier but it didn't feel that way on the track at all. And it was such a blast running the car with a 13.5, still fast just harder to overdrive the car which made for very consistant runs each and everytime.

Could be that our track is a little smaller, and nobody that I know of is running a Schuur (Motiv and Reedy mostly), but just like we run the 69T spur on our 17.5 2WD cars instead of trying to make it work with the bigger 78 or 84 it makes sense that the smaller spur/pinion would work better here too.
Also agree on the belt-drive making the 22-4 the king of 13.5 4WD -- a year ago it was about 2 D413's for each 22-4 on race night, now with the release of the 2.0 a lot of guys switched camps and it's more like 2 22-4s for each D413

Anyone know which tooth spur gears come with the TLR 22-4 2.0?

I'm still running the 1.0 but my teammates that have the 2.0 we all ran 13.5 4wd at the Jconcepts in Chico. We were geared 78/25 &26 with Team Powers 13.5 The track isn't very big. I don't think we were under powered. Our gearing is usually the same as guys running Reedy motors and R1's. Hope this info helps
