The only way to remove tweak from the tc4 is to run lightweight electronics: the electronics side of the Car has to weigh under 310grams to match most lipo packs... I run my Cars tweaked and adjust to it ...

Here's what I use on my drill press. I've drilled out several motor mount cams for fellow competitors racing with TC3/4s in our local silver can class.

I use a 1/12 Servo Futaba S9602, a Novak 1/18th scale Mongoose for my 25.5 T Novak VTA Motor

and I add 7g to the Electronics side to Balance my battery which is only 310g

But I also put 130g in the center line under the Driveshaft in the middle of the car to make weight

goes fast

I have a TC4 setup for VTA. Everything is stock except that I put a solid axel in the front. I'm running the Novak 25.5 Ballstic and Novak Edge ESC. I also have the Saxov 1258TG servo. As for the battery, I'm running the GensAce 5000mah 40c.

I've adjusted camber/toe/ride height, etc... but the car always goes to the right. Just to test, I intentionally set my steering to the left but the car will still go right. What am I doing wrong?

You have to Check your tire shimming, steering rack play, ball cup play, and grind the steering rack bolt that might hit the main shaft cup . Also make sure the steering turbuckle that connects to the servo stays clear of the rotating shaft......

Thanks for the feedback. I checked those things you said and they "seem" right to me although I'm not an expert. I did notice something. This only seems to happen at the start. It's as if there is too much torque on the rear tires. Right off the bat, the car goes right...reaches near max speed then goes straight. I then checked and notice the chassis is "tweaked." I hope I'm using the right terminology.

So I tried raising the rear and the LEFT tire lifts earlier than the right REAR. I check the front and it's the opposite. So the front RIGHT tire comes up before the front LEFT. It's opposite corners.

Could this be my problem and if so, how do you adjust a TC4 tub chassis?

Both left and right Tires on either the front or the rear should come Off the ground at the same time. To adjust that, you need to tighten the droop screws that are located in the A arms until you get both Tires getting Off the ground at the same time. You also need to make your suspension uptravel about 3mm before the Tires come Off the ground...

Also Saxo, if the front right tire comes up before the front left, you will inevitably turn right on sudden acceleration. If the rear left comes up before the rear right, you will spin easier turning left than turning right........

Thanks all for your suggestions. I had to tighten the rear diff cause it was too loose. After that I adjust the ride height and ensure camber, toe, etc...were set correctly. Now my TC4 screams straight! So happy. Thanks again.

I have a 200mm HPI Mustang GT-R I want to run on my TC4 sport, but I picked up the standard offset X-pattern tires.

What is a good offset to use to run this body, any suggestions? I think the 190mm wheelbase might look funny on a 200mm body.

Everything is still in the package as was deciding on what to do.

I picked up a 190mm S2000 body as well, but really don't care for the looks of it.

EDIT:

Also, what would be a good start for gearing for 17.5T ? I have a Speed Passion combo to go in this, but not a clue on where to start for gearing.

EDIT EDIT:
What is the smallest spur I can fit on here? I'd like to run the 59T if I could.

I have a TC4 setup for VTA so by rule, the front wheel/tires are +3mm offset and the rears are +6mm offset. Looks cool since VTA bodies are 200mm in width. I did put on a 190mm sedan body using the same wheels/tires and it looks a bit funny.

So I sugest you start out with 3mm offset.

HI,
I have a TC4. i run a 10.5 LRP K4 motor with a 72/25 set up. i mostly bash with friends on black top. is this a good gear set up for this kind of motor?? Also i have here a lot about shiming the TC4. i shimed the steering rack, what other areas do i need to shim and whear do i get the shims from aside from Assoicated for the Tc3/4??.
