Good to know about the tc4 ARM mod.....

I am not sure myself, as I didn't measure the changes. I just copied what Randy and Rick revealed in pictures on redrc.
I guess the geometry changed (maybe not the rollcenter in first place) and gets closer to what Yokomo has.
My own experience before was that you can make the car very fast with stock parts, but it was never as smooth and consistent to drive. So after the change it is much better on the long run. Just more predictable, consistent and forgiving. And for us good but normal guys this can easily bring 1-2 seconds on a five minute run.

It's a lot of geometry and physics. The TC6 arms i believe are longer so just bringing the inner hinge points to match the total rear width is a small part of the total effect.

a shorter arm will change the shock mounting position on the arm which changes the angle and depending on how much the resting length of the shock which will affect the pre-load necessary to maintain ride height as well as damping properties of the shock. The shorter arm with the same inner hinge points will affect camber change at the hub, speed/re-activeness of the arm to bumps, etc etc etc... i dont think i'm even 5% into what the changes do overall... just to one side of the rear suspension and not getting into how that affects the overall car.

that's part of the magic of tuning, i'm pretty sure 95%+ of us do not have the tools and equipment to actually test an isolated change without making a change in the overall setup.

So the tc7 will be a total other car. New arms, hubs, other LG steering rack, undepended from floating Servo, new shoks... Improved Swaybar system... I'm exited...

I am using a Yokomo shock end and spring retainer. For asphalt I run my shocks at 62mm, for carpet I cut about 2mm off the shock shaft and run them at 61mm.

A-Main just lowered the TC6.2 price to $369 so the new car should be out soon!

Thanks. Do you have a link to a setup sheet using these changes? Also, is this something that is used on both carpet and asphalt?

I would imagine that the new plastic on the TC7 will bring the TC6.2 up to the modified geometry so it might be prudent to wait for the new parts from AE to be in stock. I would imagine the new arms and hubs will be a direct fit if AE maintains their usual rev release philosophy.

Svendc

question is, would the new car have the same bodypost positions, because i will make at ones, some new body's for this winter and next season these days...

If AE sticks to their usual rev pattern, they should be the same as the 6.2. Just the suspension plastics get updated.

hum....6.1 and 6.2 are not in the same position....not sure TC7 will match up either

Svendc

exatly, if they make changes of the geometrie , it's possible they change also the shocktowers... shocks and rollbars...but do we know that in terms of weeks of months?

On carpet it gave too much steering. Otherwise it runs very well

Thanks!

short camberlinks, arms in extreme rear possition, must be a lot of steering indeed. :-)
