Questions?? New to on road!

hey guys. New to the on road touring world. Just bought a 2015 t4 about two weeks ago. Running the trinity d4 with the tekin gen 2 spec esc. Running on carpet only. Any gearing advice will be greatly appreciated.

3.8 FDR should be close to start

Yep. Though it depends on how large and flowing the track is. 3.8 FDR with healthy dose of endbell timing should be pretty good on the vast majority of carpet tracks around.

You'll never get down to this low of an FDR with the kit 48P 84T spur though, so you will probably want to pick up a 64P 96T spur. I really like the Core RC machined spurs. They've worked very well for me. Leespeed is another good choice, I hear.

For pinions, I like the CRC gold ones, but I'm using some other brand in my car right now.

to get 3.8 FDR with a 96 tooth spur in an xray t4(internal ratio is 1.9 38/20), you'll want a 48 tooth pinion. 96/48 x 1.9 = 3.8

I'm sorry. ...I'm not familiar with that. Would you be able to elaborate?

Oh ok thank you lock and racer! I did switch spur already to the 92t 48p and I just picked up a 47t crc earlier today! I also replaced my front spool so it's not locked. Should I try 1000000wt diff?

I prefer a spool over a front diff, but if you go front diff, then 1 million CST should work OK. I've used 2.5million cst in a front diff before. It gives a little more initial turn in and has some give, so it's not as hard on the ECS', but I just prefer the way a spool yanks the car out of the corners.
