Stadium truck is on the rise!! I got one now, my buddy jus got one, and I know of a few more guys that just got some as well. Gona great racing this winter!

Got a mmp and redline 6.5t. I run on a high bite track 6800 sq ft 87 spur. Whats a good pinion gear to start and work my way down or up. Thanks

17 but that's a guess. I'm 19/87 with a 7.5...non tekin

that's a big track...18-19 might be better, temp it and go from there.

on a revtech 6.5 i have 87/18.

also with the losi rear bb spring in the front, with full length it is too much spring... i cut one coil off and it opens up more adjustment...
even with a 280g battery i cant get the front to get down to "arms level" so cut one coil and with ~200g it does.

cant wait for a real 22t front spring (green) tho !!

I asked this a couple pages back, but it's been buried since then. What's the deal with the BB springs? I'm not following how or why they work better if the spring rate is the same or similar to the standard AE springs. In my head, they're just wider, not seeing the advantage, but everyone seems to be swearing by them.

They look cooler and don't rub the shock body like many associated springs do. Realistically, I haven't heard any firm evidence that there is a performance advantage beyond that though.

A larger spring or shock with larger bore/oil volume will aways work more efficiently and consistently. There is more area to absorb the load or spread the friction.

has anyone used 2-stage pistons in the t4? it works great with the b4, I use the RPM ones, and it seemed to make a difference.

I certainly understand the larger shock with a higher volume of fluid being able to absorb and distribute load better. It also makes perfect sense that the larger spring doesnt make contact with the shock body, helping to increase consistency. But a spring rated at 3lbs, regardless of diameter, should in theory perform exactly the same as any other spring rated at 3lbs.

correct, but the major increase is that the springs dont rub, as soon as a spring rubs, that rate is affected, it helps keep performance predictable.

bb also seems like it doesnt callapse like a sb spring does, as it has more support, this also seems like it should keep the spring from dropping in rate due to fatige as quickly.

I have some info here regarding them. The 4 of us in my fam run them in our T4.1s.

Two linear springs CAN be rated at 3lbs each... but the larger diameter spring will cycle smoother than a smaller diameter spring. Theres just more material there to absorb the load. 3lbs is 3lbs unless one of the springs is progressive in design...

hey guys, my t4.1 is on the way, what parts do you recommend stocking, i have a b4 so no need to worry about all the similair parts, but i was thinking, arms and tie rods(mine seem to snap very easily, one of the most common broken things for me atleast, on my b4)(also, which size, the parts list shows two different lenghts) I know i asked several pages back but if I could get a list of basically the names of all the diff parts between the buggy and truck I'd really appreciate it.

Honestly I've yet to really break anything, but I have seen arms both front and rear breaking. I've also seen a shock tower break. That's probably what I will stock. More than likely I'll order the carbon parts kit and keep the stock as spares.

Not sure about all the different parts between the truck and buggy besides front shocks and springs, chassis, arms, and shock towers. I would assume there are quite a bit more.

Other than what you mentioned, gear diff v ball diff and that's all I know of, I'm sure there are some t4/b4 owners here who could fill me in
