Thanks guys. I will try those suggestions.

Does anyone happen to know what size the set screw is in the FT wheel hexes?

Thanks again!

Good enough Jeff, I will be picking your brain at the track next time out. I am very interested in this and an looking for a good tutor on this subject.

I'm sorry Cherry, but it's backwards. In the same way that using a softer sway bar will yield more traction at that end of the car, lowering the roll center with the 8mm mod reduces your "bind" (even though a better description is leverage) allowing more weight to transfer therefore planting the rear end more.

And you should be confused!! WTH, who started this one? I have a hunch, but the only thing that can bind suspension related is the hinge pins. Bind is the wrong terminology.

Not backwards ....

I know from experience using the c brace on my mod buggy how lowering the outside stud makes a lot more traction ....

a single lower stud makes more bind or resistance = more traction

M3x3.

This. Traction is driven by weight transfer. More transfer, more traction.

The local Ae gave me the word or term describing
how the 8mm mod works ...


Bind as like a tight suspension pin or ball cup sounds good to me ....


Kiro .... "leverage" sounds really good towards describing how more or less resistance is achieved.....

so confusing! I want to go back to bio class

yeah know ?
Why
when I first posted the picture of 8mm mod ?

I did not mention it and just you guys eyeball the thing ....

That is exactly what I have been under the impression of, but WC has a way of taking that and totally flipping it. I get if you do the outer hub mod only that you are raising roll center and taking away traction and if raising inner only you are lowering roll center allowing for more weight transfer(traction) but if done equally(raising inner and outer ballstuds) that should also lower roll center which should create more traction(weight transfer), not resist traction rolls and for high grip as WC puts it. I have read somewhere to raise roll center to fight traction rolls and to decrease grip and that is not what I am personally seeing this mod perform. It is to keep rear end from checking out when coming out of a corner when acclerating which to me is adding rear traction. How is that supposed to help traction rolling on high grip tracks. Seems to me you would want to remove shims from inside ballstud to a point but then you really start running into camber gain on compression. That is when you would also have to lower the outside ballstud to keep camber gain in check, correct?

Or is the camber gain what is making for less traction? I am so confused.

"Resistance is futile"

Another NW Short Course Nationals in the the books with 182 enties. AE wins again. On a track that looked like it was made by a Team Losi driver the Team AE guys pulled off a win in 2w and 4w. Interestingly enough the winning truck has a EXOTEK chassis on it! I ended up 8th in the A.

Outdoor racing is difficult with wind in the 20-30 mph range all day/night and my light weight set-up was not in favor of the wind. About half my laps where on pace the rest I was blown off course and sometimes I just could not see from my eyes watering. All part of outdoor racing in Eastern Washington I guess. Live and learn
