I think they are mainly referring to the fact that these are originally designed for the aluminum hubs on the 2wd stuff. There usage on the 4x4 is something new specific to this 8mm mod.

Awesome. Thanks Cain and Evil.

what will the c hub tower do to the car? handling wise? i have a set of carbon tours just sitting around.. pro and cons?

Give the rer more traction mid-exit of a high speed sweeper.
Try them, you may like or you may hate it.

ok i will try them today.. i will let you know my results this evening.. seems like my rear end is still unpredictable.. likes to dance coming into the sweeper and exiting the sweeper.. i just wish the car would be consistent and not so unpredictable! i can have a few consistent laps and when i want to push just a little more it gets all hay wire!

Since you are raising it 8mm... Just remember to add (Most run 7mm) washers under the inner ball stud if you do the 8mm Mod.

While changing to 11t Pinion i noticed, that my chassis-plate damages the motor-case! there's a big scratch in the chassis-plate, where the motor hits the chassis when landing and the motor case has some "optical" damage. Is that normal, or is my motor just too long? it's a tenshock with 4600kv

for the c hub tower mod? at the moment i only have 2 ballstuds in the inner hole at the moment.. when i put the c hub tower on do i have to raise the inner hole to 7mm?

You don't have too. Play around with it and see what you like.

If you do the c-hub mod and raise the outer ball stud 8 mm, you need to raise the inner by 7-8 as well to truly benefit from the mod. Otherwise you will not only have a completely different roll center than those running the mod, you will have a much higher camber gain rate which will probably make for a worse off car than just leaving the ball studs in their stock location.

ok i will.. what if i do add more ballstuds to the inner hole.. what will that do to the car handling wise? more stable or less stable?

i wll try both! thanks krio

The higher I raised the inner ball stud the more stable my truck got. 7mm is the highest you can raise it and still get the ball stud to screw into the mount without modification.

I have some computer m3 standoffs I am going to try. Will raise the ballstud up to 11mm

Voila!

Raises it 8mm or higher up to 12mm
