Im going to order a corally sp12x soon and was wondering if anyone could help with the corally tyre ratings. I know where purple and pink fall in line but maybe someone could list a soft to hard list of where their gold and silver compounds come into play.

thanks

About the Corally tires,

Partnr.(tires only)-colour - shore rating.

Front Tires
1418-Goldstar - 30
1412-Green - 32
1419-Silverstar - 34
1416-Gold - 36
1417-Silver - 38

Rear Tires
1406-Gold - 28 (slightly softer than green)
1402-Green - 28
1405-Orange (Outdoor Compound)- 28
1407-Silver - 30 (slightly softer than pink)
1408-Pink - 30

Standard setup: Silver front, Gold rear.

If you are referring to the X-Stock (black can) then I would highly recommend it. It has torque and RPM. Very fast motors!

Question guys-
I've never ran a 1/12 on carpet but planning on it for a big local race coming up. With the Checkpoint $$ motor w/Infinity brushes & gold springs AND 1.75" tyres, what rollout is good to start with? The track is small-n-tight...

thanks a lot.

For mod I liked double pink pinks from jaco, so the closest would be pink and the silver stars.

now the only thing i need is the corally tire truer adaptor

One more question, how low can tires be run down to with the pod plates on the sp12x? For mod I like to run around 47mm, so Im assuming they can run at least that low, but for stock I run like 43mm. Is it possible to go that low?

i have a corally arbor for 1/12 if you need one.

We developed a few design interations and worked with the shop to create a manufacturable design. Standard manufacturing flatness tolerances are less then ideal. I think the final part speaks for itself.

I've got a new JR Z3650 in my CRC 3.2r and it's making a lot of noise when I turn the power on. Any idea if something is wrong with it, or is it normal?

ANY idea guys??

I don't own the 12X, I ran a 12M.
But when I saw the prototype early this year, I saw the axle heights weren't changed. And for as far as I know they didn't changed the podplates in the production version.
With the 12M I drove with the stock spur gear (78t, 48 pitch) which has a diameter of 42.3mm, so I used the tires untill they hitted the 43mm in diameter.
With that diameter I could get the right ride height, hopes this helps.

Hey Mike D,

Which side of the rings is the recommended side to put up against the diff balls? Is it the flat side like normal.

Thanks,
Steve

On this aforementioned X-motor, what is a good spring/brush combo for the beast?

Hey GrandeGixxer,

I would try the F-Brush with a Red on the Pos + and a green on the Neg - or you can try a green + and Green - a close second brush choice would be a Trinity 4503 brush

Hope this helps

Each motor is different so try different settings. I currently use black on + and red on -. I managed to get my hands on a great batch of f-brushes!

I tried on the co27 green/green reedy 769 on the dyno it was ok on the track fast!!!!
