You should have 2 sets of inserts for the hubs. A set that the hole is dead center ....that's your zero. And a set that is 1 deg off set that plus 1 if you install them up and neg 1 if you install it down.

Has anyone ever run the rear toe inserts on the opposite sides to get more than 3* of rear toe? I'm experimenting with setups (mainly to get to know the car better) and I'm going to try the 2.5 inserts on the "wrong" sides. That will give me about 3.5* of toe I imagine. I am also going to run long rear upper links and a bit more kickup. I'm hoping this will give me a setup that drifts nicely off power and squares up immediately on power. Much like Lamar's javelin that worked with his limp wristed throwing style I am searching for a setup that will work with my ham fisted driving style. (Anyone get that reference?)

Cody's worlds setup is great. I'm just playing around to see what I come up with.

im using this set up, and it ran great,, very easy to drive. such a good starting point. but take a note that there is mistyping on set up sheet, rebound=rideheight, rideheight=droop/overall shock length. hope works on you guys too.

I've been drinking a nice wine so I hope I got that right! HAHAH!

You will find that the aluminum c-hubs will give you more steering over stock so I would imagine that the 0's will be just fine.
One thing you didn't mention, which I found out in my own testing is that although the +1 inserts most definitely do give heaps more on-power steering and while the car has less on-power understeer, they induce quite a decent bit of understeer on the way into corners.

If only there were some way to allow the car to drive like it has a -1 on the way into corners and a +1 on the way out. That would be awesome!

Like with any change, everything's a trade-off.

The HA parts are absolutely no stronger than the ordinary brown anodized parts. The only difference is in the anodic layer, not the base alloy from which the part is milled. Therefore, the HA towers won't be even the tiniest bit better than the brown kit parts in terms of resistance to bending or torsional loads.

Also, it isn't actually possible to buy the brown anodized kit towers as an official, genuine spare/replacement part. But they've long been available on ebay for HEAPS less than anywhere else in the world (to the best of my knowledge). You can pickup the TKI3 kit rear tower (brand-new, removed from a kit) for about $15 including postage.
Buy the HA if you like the colour I say (or just want to waste your hard-earned $$$).

I haven't ever tried running the rear toe inserts on the wrong side but I have tested the rear camber links in their longest configuration, inside on tower, outside on upright, to see what would happen and indeed the car drifts like there's no tomorrow. SO little traction from the rear end with the very long camber links but at least it did seem to be controllable drifting. Very progressive, but had so little grip I only left it like that for about 10mins and then changed back to normal.

Also, most people run the car with the maximum front kickup, as per all the team drivers or the kit setup, so if you're using any of Cody's setups, he always uses max kickup - not possible to adjust the car to allow any extra kickup.

Gotcha, I was referring to the rear kickup actually. The front is exactly Cody's setup actually.

I ran long links at the last race and it did drift ALOT. But as you said it was a very controllable drift which is why I'm hoping the additional toe and kickup will get it to square up under power with the longer links. I'm going for easy off power drift rather than a whipping around along with a car that squares and tracks straight under power. We'll see...

So are you referring to the rear anti-squat setting when you say kickup?

Anyone know where you can get just the inserts as a replacement part for the aluminum Hubs?

AFAIK the caster inserts aren't available on their own as the ones supplied with the alloy front c-hubs are the same as the ones supplied with the original plastic c-hubs and the inserts can only be purchased along with the plastic c-hubs as they're all part of the same parts tree (if you can call 2 c-hubs and 4 inserts a parts tree).

Sorry to be the one to give you bad news.

Actually this is backwards...the lower hole position gives you +1 caster (lays c-hub down towards rear of car) and the upper hole position gives you -1 caster (stands c-hub more upright towards front of car) when compared with the middle hole insert.

My error, you are correct.
