This is amazing!

Any chance you were planning to share the files???

Of course! Just making some final tweaks to the designs before posting them.

The rear diffuser is a little tricky, as you can't run the rear bumper with it, So anyone who uses the rear bumper for body mounts is out of luck until I design one to attach to the rear bumper piece. For now, I'm going to modify the rear diffuser to fit on the rear piece that holds in the a-arms. Currently It's made to fit only on the Yeah Racing rear toe mount.

I've also finished the underglow on the Porsche 911 RSR RWD TT02, super excited to post pics of that. I think it came out phenomenal! However my Pixel 3XL randomly decided to brick overnight the other night, so I'm sad I won't get to use the portrait mode for the RC pics, but I've got a cheap replacement phone coming so looking forward to getting some nice, dusk time pics of the car to show off the underglow!

That's the plan on mine, though I'm going for 100mph on 2s!

Hello - Just picked up one of these to race in a stock/spec class on asphalt. Everyone must run Gravity tires. Biggest issue I have seen is lack of rear traction. Before I hit the track, what suggestions does everyone have to keep the rear end well planted? Any other set-up advice?

Try this:


2 deg rear camber.

2.5 deg toe in

softer springs in the rear.

lower the rear roll centre a little bit.

Ok, since it is a box stock class - how do I adjust those without changing the parts? I know about doe and camber, just don't see how to adjust it on a box stock car. Thanks you.

If it's a box-stock class, you won't be able to AFAIK

If you're able to upgrade the shocks or get a kit that comes with oil filled shocks you may be able to get some improvements by tuning droop with the included spacers for the shaft, or some extra o-rings IIRC

Sauce the whole rear tires and sauce only 1/2 the fronts is a start.
Try CA glue on the sidewalls and 1-2mm onto the surface of the front tires.
Lay rear shocks down more on the rear, stand up on the fronts.

I had this same problem with my TT02 at the end of this past season. The CA glue trick worked amazing for me.

There are no adjustments possible with the stock TT-02 out of the box for front or rear toe, camber, castor, etc. The kit spring suspension (can't call these things shocks) is also non-adjustable and you are likely obligated to run the kit silver springs. To soften the rear slightly, I suggest you use the inner shock mount hole on the rear shock tower, and the outer holes on the front. The spring shocks use a thin plastic spacer that you can probably not use to lower the car a bit. It's not much but every little bit helps.

The Gravity RC tires give excellent traction, and as already suggested you can play around with the amount of traction compound you apply and also CA the sidewalls somewhat. On hot summer days on asphalt, I found that traction compound did very little and cleaning my tires after each run with Simple Green worked just as well. I assume your track uses sugar water (or similar) in the corners for traction.

If you are only limited to the parts that came in the box, you could put some anti-wear grease inside the stock plastic dampers. This can take away some of the bouncy nature of the dampers depending on how much grease is used. This is what I've done when I've raced with those type of dampers in Eurotruck racing. The TCS rules allow using grease or lube on any moving part in the Eurotruck class.

As was already stated, there are ways to affect handling with traction compounds or the use of super glue on the sidewall/tread of the tires.

Today was our 1st outdoor on road race with our local club. Temperature was way past 80°F so track had to be above 100-120°F.
I tested out my TT02 that I haven't touched since the fall/winter season ended in March. I slapped on my Gravity RC USGT tires reapplied some CA glue to the front tires. Checked my friction shocks had Dielectric grease (it's what the veteran recommend to use since it's inexpensive and easy to get at automotive stores; I put the nozzle on low setting and do 1-2 squirts. Just enough for 1-2mm in the body. Too much gets messy).
My TT02 felt grease, a little lift throttle rotation made hairpins easy as it made the back swing around just enough and get back on the throttle.
I'll try to post some videos later.

Alright guys. I've started posting my TT02 stuff on Thingiverse.

Have the side skirts and a few splitters up, as well as the 911 RSR headlight buckets. Also a little bumper brace I have whipped up.

The stuff is all free, but there's a donation link on the files in case you wanna buy me a coffee or some 3D printer consumables for my time and effort. I actually just ran out of new nozzles for my sub-par Monoprice MP10 printer LOL.

I have pretty much posted all the Aero stuff now.

Look for a pic when it gets dark tonight of the latest thing I have designed and built for the 911!

So here she is, with my latest design implementation.

Underglow with 14, 180 degree, flat top 5mm red LEDs. They are on a separate harness from the headlights and tail lights, and draw less than 300ma. All wired in parallel. Each section has a plug. The bumpers and both side pieces. I designed and 3d printed the sides, and just drilled a few holes in the bumpers.






I'll try to get pics when its a little darker out, but the light covers the entire underside of the car and it looks good! At least to me it does LOL. I know underglow isn't for everyone, But I wasn't happy with what was available to add underglow currently.

I'll probably do the wiring better on the next set and maybe make a cap to hide the wires on the sides.

Full aero underkits designed for 2 bodies now. The 1991 Audi V8 and the Lancer Evo VII Tommi body.




Diffusers here for the Audi (may fit other bodies, Mounts to the rear bumper plate so can't use it with a rear bumper assembly). https://www.thingiverse.com/thing:5392178
