Cool, thanks for that info. I like lots of steering so I think I'll stick with my old setup and then make changes and see what I think of them (what an idea!! ).

I was wondering if anyone could point me to a good starting setup for the Mi3 for foam/carpet. Haven't raced in a while and am starting to feel the itch again.

Well the nice thing about the short bellcrank is that it actually doesn't seem to take away steering, it just makes it more controllable. But trying them back-to back yourself is a brilliant idea, I don't know why anyone hasn't thought about that before
lost - i still favor marc mcgoo's carpet nats setup the best. (3/13/2008 from that link)

just make sure to reset your radio epa's as the shorter rod will most certainly yield a larger turning radius. and double check your toe if keeping the same pivot hole (in the support plate). when the tie rods go from angled back at the hubs to straight (parallel with the dogbones), the car gets toed in a bit.

I am trying to get my head around shock rebound - some setups call for 50%, 70%, 100% rebound.
Can someone tell me what rebound I get if I build a shock 'normally' i.e. put in 30wt oil up to the top, put the rubber seal on and screw the top on with the shock at the fully extended position.
And also how I build a shock to get different levels of rebound?

Now rebuild the shock with 30WT oil and put the bladder and close. Push the shock shaft in and then let it go...it should only "rebound" back about 1-2mm...which is like 10-20% of the 10mm max shaft extension.
When you build the shock "normally", all you get is about 10% rebound at best. To get more, use rebound foam, or o-rings which you can place on top of the shock bladder.
Xray shocks use rebound foams, HB Cyclones, AE TC5, etc...most come with small cyclindrical foams which you put insise the shock's bladder to get more rebound out of the shock.

Are there any recomendations on foams on o-rings that give the different levels of rebound?

What you say makes sense - I will check my shocks tonight when I get home but I thought that mine, built as normal, were pretty much rebounding out the whole way with no foams on o-rings in place?

For rebound foams...some use Tamiya or MMR rebound foams, or Xray. I'm sure someone here can post where they can get them from.
Dont forget to go thru Adrian's posts on how to build an MI3...especially the shocks section...here's a link:

Really good info, and he covers how to build the shocks, rebound, etc.

Anyone using MMR or other kind of rebound foam?
Tech Master
It depends on the shock caps. With 3.5 caps (or older EC ones) building "normally" will give full rebound. For less rebound, you push the piston up toward the top of the shock before putting the diaphragm on.
Tech Regular
MattW - does it follow that if I push the piston up 50% of the way then I get 50% rebound? Chris Ashton's carpet setup talks about 50% rebound.
Tech Master
Yeah it's not far off that - it's not an exacting science, but it's not a million miles off.
Tech Regular
And taking it a stage further does putting the foam pieces or o-rings on top of the rubber diaphragm make for faster rebound?
