Alternative rear shocks for Brat / Frog

[njmlondon]

I am finding the stock shocks for my Brat are just too stiff.

I am sure I read somewhere about using 80mm dual springs as a decent set up. Can anybody offer any thoughts on what shocks I should try.

Ok I'll chime in.

I use 70mm shocks from Yeah Racing. Not sure If they are still being made.

Another way I solved this is using the original dampers ( Re re ) with Losi Mini T aftermarket GPM alloy shocks. Just used the springs of them and worked well.

These shocks really suit the front of the Brat/Frog too.

Part of the problem is the geometry of the rear trailing arm setup, similar to the Falcon.

I use the 70mm Yeah Racing shocks too, but any shocks around 65mm-70mm should work. You can put softer springs and thinner oil in them to compensate for the poor trailing arm shock geometry when compressing, but once you get this right, the rear end tends to sag, and since it doesn't have a lot of travel it hits the suspension limits a bit too much. Tricky to get right.

The best thing to do is use the original balloon spike tyres. It seems that these large soft tyres effectively form part of the suspension, whether that was by design or not.

Another Yeah Racing shock guy here...  Really thin oil...  Soft springs...  Its like butter back there!

I'm using foamed ProLine Road Hawg IIs on HPI Super Stars.  Helps prevent roll-over...

Thanks for the advice. 

I read somewhere (but cannot find it now) that the geometry at the rear meant that they compress in an uneven way. By that I mean the first part of travel is really soft and the latter part really hard (at least I think it is that order... it may be the opposite!). Either way, apparently the dual spring set up could counter this, using stiffer springs for the first bit of travel and softer springs for fuller compression. It made sense to me at the time.

I have some lovely 70mm RC4WD EMU Nitrocharger shocks and a full set of alternative springs for them, so I may have a play around with them to see what I come up with.
