While probably not as important for a basher, it is essential for a club racer to perform regular maintenance to keep their cars in tip top shape. I keep a race log, with a different worksheet for each chassis to include columns for: Date, Hot Lap, Hot Qual, Hot Main, Hot Consistency, and Notes

In my notes I will record every rebuild where I like to go no more than 3 race days between rebuilds (approximately 3 hours of total run time), I also note when I replace tires, break a part, or any tuning changes that improve my lap times/consistency for a given track condition that may have changed.

I color highlight my track records for a given layout, this allows me to "race myself" so if I don't make the podium but beat a PR, then it's still a rewarding experience. I will reset my PR's every time there is a new layout.

A typical rebuild consists of a complete tear down by removing every single bearing, prying the rubber seals with a hobby knife and flushing dirty bearings with WD40 Dry Lube, then re-pack with fresh grease and snap the seals back after wiping them clean with a terry cloth; bearings that show clean grease do not need to be flushed, I use white lithium grease and wait for the grease to turn black before they are flushed. I apply fresh grease on all rubber seals in the diffs and shocks as well as apply fresh fluid. If shock fluid is still clear, I won't dump it, but once it turns into a milky grey then it's time to rebuild the shock. If your diff fluid is going past milky grey and turning brown or black, then you are not servicing your diffs soon enough, dark fluid is dirt that will cause your parts to wear faster. Check mesh and replace any pins that are starting to form flat spots. Then I will go over the entire car with a fine tooth comb inspecting for hairline cracks or any worn parts that need to be replaced. Finally, I double check all my setup settings on a setup board.
Sample Race Log snippet for a given layout with PR's in Yellow and Broken PR in Orange, all PR's are reset when track layout changes, goal is to set a new PR each race day to show improvement:

Note how my overall finish order is not tracked but my Stack Rank is what I record for my PR, this encourages me to run in more popular classes where it's more important to see how many people I beat rather than what position I finish... sure I could pick a less popular class and come in 1st place every time, but that won't make me a better driver ;)

Our local track did an intro to racing clinic. I wanted to learn more about set-up and general maintenance. My son wanted to get some driving tips. We both learned a lot.
The big takeaway from one of the sponsored drivers, who was a big part of the clinic was having a consistent setup and checking to make sure the car is always the same. Then the big variable is the driver.

Yup, there are many sportsman level drivers in my area who will likely remain sportsman indefinitely because they refuse to do maintenance nor put any effort into tuning.

I was guilty myself the first 5 years I was into club racing... I pretty much ran box stock setup and waited for something to break or would buy a new car rather than doing a rebuild, ha!

The past 8+ years I've been taking things more seriously and have grown to appreciate the importance of both maintenance and proper tuning :)

I use the Hudy cheat sheet here for 90% of my adjustments:

Like many things you get out what you put in….
I understand the value of maintenance, and I want to keep the car in good shape so my son can have that consistency, and keep improving. We’re looking to do some Tuesday night club races this summer, when we can be more flexible on his bed time.
I will print off the chart to keep as a reference. Good stuff

Thanks

much appreciated,

Here's another resource which does an excellent job of explaining what each tuning option does to help compliment the chart above:
https://www.teknorc.com/wp-content/uploads/2014/06/Set_Up_Guide.pdf

Note that the Hudy chart was designed for on-road racing and misses some key tuning features that are fairly important for off-road tuning where the TEKNO guide helps fill in the gaps.

Gotcha. We are still running the kit setup, but I’m looking to make some small tweaks as he tends to keep the hammer down into the corners. Having said that they just put down fresh carpet, and I’ve mounted new tires, so he’s gonna need to ease up so the car doesn’t high side….
