Hey Paul,

What t-bar and shock settings are you liking on the 12x?

I am using the Hotbodies shock with 40wt AE oil. For the Tbar, Robbie has some new ones coming out that I have been testing. He said they will be available at the snowbirds in his shop. I have some that I can give you when I get down there.

I have posted this in the 1/12th thread also, but more help maybe found in here with the 12x .... anywho...

I've got a few questions....

There is this sweeper (in the pic) which comes off the main straight, and you carry alot of speed through this corner, But 3/4 of the way through the sweeper my car starts understeering and i have to button off the make it around the sweeper, whilst some other 12th drivers carry more speed through there.

pic of the sweeper:


we don't use tyre additive

Chassis: corally sp12x (corally spec, standard front)

What i've tried:
Soft and hard T-bars

Soft and hard fronts,(even the softest compound still 'pushes' / understeers mid corner on power.)

hard and soft side damper fluid

Soft and hard front springs

different shock fluids / tensions.

I'm using pink rears, but thinking of going slightly harder to see if i can get more front traction.

Or i'm actually thinking of putting some weights on the very front of my 12x front, as there seems to be alot of biased weight to the rear.

Any tips?

Also....

I'm still a bit clueless as to what levels you adjust the tweak screws on the tbar for what surfaces etc etc?

cheers for any help... there is always more to learn with 12th

How much are you guys shimming under the front of the t-bar? I started Frechettes car off with .040 under and it seemed very balance.

I don't have anything under mine. I think it has enough steering with out it but we will see at the snowbirds.

Jeff didn't have any spacer in Cleveland, and his car had plenty of steering.

Thanks, Paul. Jeff used the silver center spring with 30wt AE oil in Cleveland and O-rings under the 1.6mm T-bar to stiffen side to side. He said it did NOT need any more steering. Jaco 2pink front and yellow rear tires.

I've been testing the new tbar as well. Main reason I haven't posted my setup is I wasnt sure we could talk about them yet hahahaha. I'm still fiddling around with it though, I'll post a final setup later this week I'm thinkin.

Overall first impressions are AWESOME

Default Spacers?

Hi,

What solutions are you guys using to keep rear track width correct while using jaco prisms?
I'm considering machining AE style rear axle spacers, but maybe there are some wheel hub kits or something?

Most are just using a bunch of CRC 7mm axle shims. They are the only onws I know of that make shims in the right dia for our axle.

We use the Corally extended pinions with no problems.

Yeah, Corally's diff/axle setup is a little different than others. Using those pinions that Larry suggested will solve the pinion issue.
