Using different size pulleys front or rear was a 'tuning' option touted by Losi years ago with their XXX-S sedan. You could under or over drive one end of the car as an option but I don't think it really proved to be of any advantage. The way I see it, one set of wheels would be constantly slipping therefore reducing traction and isn't something I'd personally want to try.

why im asking this is im going to be running outdoor blacktop racing, and im thinking that if the car is lose you would be able to run the front tire faster to help pull the car strait.

Only possible pro would be for drifting. your front and rear tires would spin at different rpm.

I agree, I don't think that would work for racing, I would just use the suspension setup's to gain rear grip.

Hey Guys

Im looking into this as a VTA/2nd Chassis and was wondering what upgrades are recommended?

I did a search for upgrades/mandatory but could not find any list.

So could someone list the recommended upgrades for this kit?

I am just putting the finishing touches on my electronics so this is not based on experience. It is based on this thread and a few racers input. Here is what I went for:
Vertical motor mount version 3
19 tooth center pulleys
Aluminum center pulley mounts
Tamiya shock bladders and o rings
Titanium turnbuckle set
Shim sets
Non stock differential and shock fluid
Aluminum shock set

The only ones I feel are have to haves are the vertical motor mount ($17) and the Tamiya shock stuff ($5).

Vertical motor mount, 19T pullies and alloy spur holders are what I would consider mandatory. Titanium turnbuckles when you get tired of the stock ones having round rings instead of machined in hexes/squares for adjustments. Same with the alloy shocks -- the clip on adjusters get old. Everything else you can add if/when you have an issue or break something or just feel the need for CF/alloy.

I've got 3 Zero chassis and 2 Mini chassis that I use 3Racing shocks on. Counting in my head I think I've got 28 3Racing shocks currently on chassis or ready to go with alternate springs/oil and I've sold off some of the plastic bodied ones. I've never had an issue with any of them leaking. Other than the color of the alloy I think the Mini shocks are identical to the Zero shocks. Build them carefully and make sure all the plastic parts are "clean" and don't have any burs or sprue remains. Make sure that you don't damage the o-ring when sliding the threaded portion of the shock shaft through it. I normally assemble the bottom portion of the shock body and then the top portion of the shaft. Put a couple of drops of shock oil into the body and then slide the shaft through. That way it's coated with the oil when it slides through the o-ring and the bottom of the shock body helps keep things aligned so threads have the least chance of damaging the o-ring.

Associated green shock slime also works well to protect the shock o rings.

I agree that the stock plastic shocks are perfectly fine. My choice to upgrade was made from vanity not need. The threaded shock bodies are nice.

To get it to race VTA? I would say the Vertical motor mount, might want to try the stock one I use it without problems, you just have to take time placing the hex bolt on the mount before you bring the motor up to it.

I would also get the Alum hexes for the wheels. Other than that you would be OK for VTA. Alot of people say to change out the pulleys, but I have never seen a car with the 19T pulley and the other 3 guys i race with all have it stock. Never had any problems.

Not sure if it's OK to post links to my build and test drive video but here it is. I was very happy with the first drive. I don't have any point of reference as this is my first on-road RC vehicle. I must say it was pleasant and easy to drive.

Man that thing is quick with that stock Traxxas brushed system.

How do your tires look after that run...

Thanks for all the replies guys.


I have the Sakura D3 CS Drift car and its a great piece of kit. Ill look into the motor mount. Is the Front One Way worth investing in? I know its like magic on the Drift Chassis.
