I also forgot to add:
17) throttle expo probably not advanced
18) throttle trim not advanced(increases corner speed)
19) throttle acceleration not advanced
20) esc minimum drive not advanced
.........after tweakin these twenty steps, you should be able to knockoff at least 1.5seconds per lap...just sayin....

How do you lighten tires?

Well to lighten the Tires, I weigh the new Tires(34+grams) first, and then I spin them on a truer and file Off two to three grams Off the rubber surface... If you want to go further, you can use the Xceed wheel trimmer (#103068) to take some rim material Off but you'll only be able to remove One gram or so that way before you weaken the rim too much, then you balance your Tires.... All in all , I got my Tires down to (30g/31g) for a 12gram total for four Tires.... The carbon fiber shaft saves 7g to 8g close to the Center of the driveshaft rotation, but this saves 12grams away from the Tires' Center of rotation, which should yield better acceleration, brakes, higher battery voltage through the run, etc.... Of course, if this mod is used in combination with other rotational mass reducing mods(Alu spool/diff oudrives/input shafts), you will see lots of improvements in laptimes....

I think the only real problem the DC4LE has is that the chassis is too wide, but that can be fixed with a bandsaw and sander. I kept dragging the edge of the chassis, but I think it was the bump on the sweeper that was rubbing, not during normal cornering.

I won the C-main, car was really not 'better' but was driveable with dry tires, at least for the first few minutes then I trac-rolled it again, twice. The grip was just too high insane high, hell, it was too high for 1/12 scale. If you tried to run the car normally even an inline-chassis 1/12 car would just roll over. Even with dry tires running after 10 laps they were so sticky if you unbolted it from the car it would just about adhere to the underside of the table!

Hopefully there will be a few changes for less grip next year. I think it makes for better racing to look for grip and handling instead of looking for less and traction roll.

I do agree with Desert that the body needs to be thinner... The hole under the motor is too big, and limits how thin you can make the body.... Nevertheless, you can still get the body width down alot, more on the battery side though... I can see 10mm Off the battery side, and 6mm Off the motor side, but I still think setup and shock oil thickness is the key here.... I only use 80wt oil in my tc4's....

Holy cow 80wt? What springs do you run and on what type of surface?

Where I run we have a concrete track, surface similar to asphalt, and we are running oil wts from 25 to 35 (AE) and springs from green to blue (AE).

I run 80wt with full rebound on all surfaces, asphalt/carpet, and it calms my Car down alot... No twitchiness, no darting, no Quick traction roll with low roll centers and blue front springs/ silver rear springs.... I run 80wt in my mini m03 also with great results.... Lighter oil make the Car react too fast. I would rather have a slower reacting Car to gain some consistency, but that's me....

I think our track is just way too tight for that kind of setup. We need the car to react quickly but be controllable. I tune to get as much steering as I can, then tune to prevent the rear from stepping out. Just on the edge of control.
