Default Possible Droop problem with RTR T4

I picked up a used RTR T4 to have my daughter run at the races, and I noticed that the rear droop doesn't look very good as the arms hit the rear dogbone axle cup. If this contact wasn't there, alot more droop could be achieved.

Is it commone that this is a limiting factor in droop? Should the cups extend in so much that they can on droop hit the suspension arm bracing piece that is close to them.

And before you ask, no I don't have the arms mounted upside down.

If it's for your daughter then she shouldn't care at all but all you need to do is trim a little material from the hub and you'll be fine.

Thats true but I want to make sure that its built right.

Looks like this may be just how it is I guess. Will take pics later on.

Please try to check the rear shocks. The previous owner might have missed the spacers. There should be 3 x 1/32" downstop spacers inside (see manual).

You're probably not imagining it. I had the same issue on my son's T3. Mine for some reason was no issue.

However being race day I took the fast easy way out. Dremeled on the arms a bit to let it clear. Thanks for the comment on the shocks... I wondered why this happened. Makes sense.

Be careful if running dogbones, It sounds to me like someone took out the spacers in the shock for more travel. if you are running bones Put a small piece of fuel tubing in the pockets for the bones to sit on and be centered. I had the older T4 rtr and did this for more travel but lost a few bones till i figured it out

MIP CVD axles would be the easiest and best way to go. You wouldnt loose dog bones either.

Here you go...

You can also check if the eyelet is fully screwed into the shock shaft.

Thanks guys, especially for the pic. Really isn't too much droop then, will be more by default on the cvds than the dogbones as the axles go out so far.

I'll look and see about some CVDs, though the dogbones can work in the right conditions, so will hold onto them as a tuning aid.
