I run stock and don't change it.

We're running the standard flywheel and clutch bell of the RTR. Problem is the clutch shoe springs brake really quick. 1 or 2 days of driving and bang...they brake. It doesn't matter whether we use the 0.9, 1.0 or 1.1 mm springs.
Furthermore we use the 2.5x5.0x0.5 mm washers underneath each shoe to allow for free movement as much as possible.

any thoughts on the quick braking?

-2mm is what we use 99% of the time

Would you say it's better to have a stiffer car in high grip tracks and more flex on low grip?

One of my cars runs rtr clutch, and I've never had that problem. In fact I blew a bearing but never the springs. Sorry can't help! Maybe send a photo of your setup?

Hey guys finally getting around to putting my 3.1 shock towers on. What screws go where for the suspension mounts? All looks confusing to me. Is there any instructions on which screws are used for where? There are 4 longer screws too with 2.5mm hex drive, and then all the smaller rounded head screws. And also 4 lock nuts. Really unsure which goes where.
Also noticed in trying to put the screws into the back of the upper shock mounts, to mount to the shock tower, the thread was very stiff and almost feels like
It doesn't want to take that screw. Confused!!

OK here is the rundown.

(1) the 4 longer screws (2.5mm cap screws) are for the UPPER shock mount. First, use the black cone washer along with the 2.5 hex screws....LONGER one for the rear shock, shorter one for the front shocks. then mount to the shock tower, then screw in the offset spacer (greenish gray color thingy), same thing, longer for rear shorter for front. Then mount the shock on and use the locknut to close it. Yes I believed they machined the thread at the end "tight" for some reason, just need to screw it in a little and it will thread it in...

(2) Lower mount are the same as the GT2.0, one button screw (longer one for the rear shock shorter one for the front shock) and one set screws for each lower mount, simple as that.

Thanks for the detailed info solara,
But That's weird-
Look at the serpent page and it seems to me that the longer ones are at the front to offset the shocks so they don't bump into the camber links. They also in these photos seem to have the original screws into the shock itself, and a button screw as the mount to the tower.

I also just tried to fit the longer cap screws as you suggested. The shorter ones worked with the shorter shock mounts.
The longer cap screws didn't even with the longer shock mount and the spacer for the cap screw.. The non-threaded section wouldn't screw in far enough to be able to screw in flush with the shock tower. Ie the non threaded section Hit the thread about 2mm too soon. That is including using the spacer. This means my upper shock mount has 2mm of wobble.

The black cone washer needs to be 2mm thicker to make it work OR the longer 2.5mm hex cap screw needs to be threaded the whole way instead of non threaded the last 10mm or so. Make sense?
Problem is, if I use a washer to space it the extra mm or two, it would give me not enough thread at the other end to bolt the lock nut onto.
All else is working fine now!

Are you able to use the 4-shoe clutch?

That said, we run the RTR cars in the UK under a 'stock/RTR' class and I have 2 buddies who ran the whole season and did zero maintenance on the car and clutch and didn't break anything including the clutch springs.
