I picked up a used R5.2 for some light racing, and while I was giving it a once-over for dirt/damage/slop, I noticed that the aluminum part of the tube dampers is flared slightly. It looks like a repair was attempted as well, but that could just be from aluminum fatigue or something.

I don't really understand how the tubes could have sustained damage in this way, as the open ends are mounted inboard.

It's my first time racing 1/12th anyway, but is this something I should be concerned about?

The tubes may have been damaged by hitting something and making the pod twist.
The aluminum tubes are $6 a pair, I would get new ones to be sure both side have equal dampening.
Also make sure the damper tube shaft part is not damaged or scratched.

I made a video on "How to polishing your kingpins". The kingpins used in the video were 12R5.2 kingpins

I followed your video, along with hand reaming the steering blocks 1/8". Huge improvement.

Hold on there, you have another week to go. Looks like you got an awesome package setup for your 1/12th scale. Best of luck!

Yes mate, all's left to get is a couple of bodies,a charger,and get some tires truer.
I got one body but the right rear is messed up...like it was snatched from the mold to quick. I'm "anal" about perfect Lexan. Love to paint and have received many awards in 1/24 scale and HO in the past.

Default Active Castor Settings

We have a small low traction club racing track.

I have to assume it is probably more bumpy than our wcics racing carpet and much less traction at the club level.

I thought about putting the active castor at 5 degrees as so indicated in the tips section. Usual is 10 degrees; good idea?

I am using the 3.25 degree castor adjustment as I feel the car has alot of steering already.

As a starting point for bumpy, lower traction conditions, I'd recommend to up your tire size to 43 rear/41.5 front as a minimum (you could go a little taller still: 44/42) and up your height to 4mm so that you're not bottoming out over the bumps. That will make the car driveable and you can tune from there.

Running less reactive castor will take away a lot of steering once you dive into the corner. If that's what you need, then go for it. I normally stick to 10 and tune with other adjustments. You could go with 1.8 degree castor or take camber down to 0.5 degrees to take away some steering.

I purchased one of these bad boys and Ill have the kit on Friday. Ive ran 1/10 off road indoor clay for couple of years now and thought these pan cars look real fast and harder to drive . I plan to pull my 6.5T LRP and ESC from one of my cars and use in the 12r5.2 until I decide If I really like or not onroad cars. What range of pinion would be good start at TQ racing track? I see some cars with huge gears and others with small.

Wow. A 6.5 is quite a hot motor for running in a 1/12th scale car, especially for someone who is new to running 1/12th. In the US, by far the most popular motor choice is 17.5 and even those can be a little much for someone who's brand new to the 1/12th scale arena. It is probably not a good idea to try learning how to drive a 1/12th scale car with the rip of a 6.5 strapped into it.

Start somewhere around 40 to 45mm rollout
So like
43mm rear tire
90t spur gear
27t pinion
RcRatio app is great for rollout maths

I know i know. I have a good throttle finger and been driving RC cars for many years, I just don't race anymore due to working weekends for last couple years. if Its to much I'd buy a smaller motor if I can't drive it. I figure I have Mod motor might as well try it. I LIKE GOING FAST.
