Here's the Kyosho o-rings I use: Kyosho P3 grooved o-ring

How did you fit the TBR front bumper?Ti turnbuckles have arrived. The rest of the chassis material, and body from HH should get here in the next day or two (hopefully!). The power system likely some time next week. I'll be cutting it close since Feb 18 will be Race Day for the "AMP'd" Circuit.
Last night began removing the RTR electronics and cleaning up the chassis.
Here's the AMP MT as it is currently (with RPM steering bellcranks, Traxxas Big Bore shocks, Turnigy 1258TG servo):

Here's a look under the hood:

Traxxas Big Bore shocks in the front with stock ECX springs. I've found the Traxxas dual-stage springs to be a little too stiff for the AMP chassis. Like the Boost, this chassis design has a SERIOUS rear weight bias and I'm still struggling to get proper sag at the front end. The longer suspension arms have better leverage on the shocks so there IS a tiny bit of sag but tuning for the track will be that much more difficult.
Here's the chassis with the stock power system removed:

I removed the upper suspension links and began installing Hot Racing front spindle carriers, and serviced the stock transmission. I briefly considered just buying a set of metal gears for the transmission but in the interest of science I decided to see how long I could go before the stock gears go KABLOOEY on me.
I'll be running a shorty battery pack for a couple of reasons: remove weight from the rear and provide enough juice to the motor. I'm trying to figure out a way to attach a battery stop to the OEM battery strap. This is not a primary consideration due to the time constraint so I may just use a foam block.
Next up will be finishing up the chassis upgrades and suspension tweaks once those parts arrive. I'm waiting for the weather to get above 50-deg F so I can paint the body.
Not sure what you mean. I’ve done 2 amps with TBR bumpers and the stock screws are the correct length and line up perfectly.How did you fit the TBR front bumper?
Did u make new screw holes as i find they don't quite match up and did u cut the xtra length. Pls help as I'm still some what new to this. TIA?
BTW, with your 13.5 t motor, what size spur and pinion were you running? The old 13.5 motor that I had bit the dust so I'm either going to invest in the new Hobbywing G3, Tekin Redline Gen3, or the Reedy S Plus. I'm running a Reedy 8.5 T Mach 2 in my tlr 22sct 2.0 and it's a rocket. I've had good luck with Reedy Motors, and Tekin. The hobbywing G3 from what people have said, is a little soft on the low end. I don't know if it's because the G3 is a two-pole motor, not a 4 Pole. I would rather have a 4 pole motor and just turn down the punch in the ESC . Have a great weekend.Cool! I'm looking forward to seeing what you do with the car!

Razor my friend, welcome to the fold. You are amongst friends. I'm excited that you got an Amp. They are fun trucks.I just got an AMP MT, enjoyed this thread a lot.

Yes, the stock brushed motor is sloooow. Something in the 3200-3300 KV will wake it up for sure. You will definitely want to upgrade to the all metal transmission.Thanks, pretty neat little truck. Pretty darn slow though, will be good to put in a faster motor.
Try out the 3200 KV motor that you had in your stampede lcg. That motor would rip in the amp.Thanks, pretty neat little truck. Pretty darn slow though, will be good to put in a faster motor.
