The screws that hold the upper shock mounts are 4-40, so whatever size is needed for that.

I can rock the spur back and forth between the pinion teeth however when I turn the spur it feels like something is binding. Is this normal?? When I put the 19 tooth spur on the spur can spin really nicely. I don't understand what's going on any help would be appreciated.

Thanks again!
Had you recently done any tranny work? I had this happen once and it turned out the screws that hol the motor plate to the tranny were sticking out and hitting the slipper clutch plate.

Anyone have any recommendations on a setup for med/high traction smooth clay?
Front end
Shocks 27.5wt #2 piston 3 limiter 1 on the tower outside on the arm brown springs.
camber link 1/a/2 washers
30* caster somtimes on high bite I will go to 25* to mellow it out some going into turns.
Steering block in the middle.
2 washers for bump steer.
toe- 0
Ride Height 24mm

Rear end
Shocks 25wt #2 piston 2 limiters 4th hole on the tower inside on the arm green springs
camber link 1/b/ 1 washer with the u brace ground down and the new c hubs.
1* of anti squat
3* inboard toe sometime 3.5 inboard toe. More toe will lock the rear in a little more.
0* hubs Middle wheel base (blue washer infront)
Ride height 24 mm
If your track is smooth sometimes I put a black sway bar on the rear. It helps stable the rear out. Might be something to try if you want.
set the ball diff like the book says.
1/4 oz in each rear triangles. 3/4oz on reciever side.
all washers and limiters are .030

This a beast setup for the med. clay indoor.. let me know

Will still need the Ae hub in order to achieve the lower camber link position the C hub offers....

What FDR do most use for off-road clay tracks on their T4?

I'd try setting your throttle points on your ESC first (If you have not already done that)

If your using NiMh or NiCd packs they could be dead... Over time if left they will go bad

Make sure your throttle is at 100% on your radio when setting it up (Brakes also)

Ok well that was the problem - throttle setting on radio was set to 0%...now new problem is I totally stripped my spur gear...I'm assuming this happened due to my lack of properly seating the motor onto the pinion gear....before I purchase a new spur gear, can anyone recommend the best spur gear for me to purchase? My motor setup once again is the Reedy 540R 3900kv brushless paired with an Associated XP SC-450BL brushless ESC. My pinion gear is a 48P-21T...

Thank you so much guys for all of your help!!!!
Carmine.

Our local on-road track in Indianapolis is running stadium trucks for oval racing! So, I'm going to give it a try with my T4 tomorrow night. They have set the rules with 13.5 max brushless motors, foam tires and minimum 1/2" ground clearance.

I lowered mine for this first try using the zip tie method. If I like it and want to do more, then I will do the fuel tubing over the shock shaft inside the shock housing method.

Dropping the T4 down this low sure makes it look like a different truck! See pics. Mine is at exactly 1/2" with battery on board. Those are JACO 2.2" Eliminator foam tires. Perfect for the T4. Most are using Paragon traction compound they told me.

If you want a durable b4 then buy an rc8.2be instead. The B4 is anything but durable.
