Race Clod basic suspension set up

[B.M.T.]

I'm about to start my first racing Clod build, and I was wondering what works for people?

There is no MT racing in Sydney, dare say the whole of Australia, so I don't have anything local to look at or ask about.

I guess my questions revolve around geometry, mostly. Do racers prefer to run a little anti squat on the rear, anti dive on the front, or try to set the top and bottom links parallel?

what terrain do you plan on running on? and what chassis are you going to use?

Easy answer, I have a CPE Terminator CF full race kit in transit right now.

Slightly more complex answer... Smoothish ground but jumping. I guess my local 1/10th off road club's track for lunch break amusement, gravel car parks, grassed reserves. Certainly not crawling.

I will be installing a matched pair of 21 turn Titans, or my pair of Mega 360's for it's initial runs, but might move on to a pair of Traxxas VXL systems once it's sorted and I get used to how it drives.

In response to the geometry question if I understand it correctly you are asking about the tilt in the gear cases with respect to front/rear for each individually?

Links parallel is tough to do with a clod because you need clearance of the upper links when the suspension compresses and the gear case comes up into contact with the upper links

In the rear I like to have "pro-squat" if that term even applies in this case which would mean the axle tips in towards the chassis lowering the motor and making it harder to lift the front wheels up.

In the front you'd want a less dramatic tilt, but still slightly in towards the chassis which would be measured I'm assuming in "caster?" The more caster, the less responsive the steering will be, which is highly dependent on what surface or tires you are running as it is with any other race car.

for shocks: GENERALLY... oil between 30-50, soft-medium springs

Thanks for that.

What I was thinking about was, best explained like this: Viewed from the side, the angle of the top links in relation to the lower.

I had another CPE chassis a while back, but for crawling. The default set up had the top links "higher" at the chassis end than the axle mount end, which caused squat at both ends under load. I reversed this for crawling. Watching racing Clod videos, they seem to really hunker down under acceleration, but I was not sure if this was just weight transfer onto the rear axle or intentional settings to lower the chassis and center of gravity under power, but allow the suspension to drop to full travel when not... i.e., in flight.

In regards to castor, I am surprised no one has made Clod tubes with clocked axle "c"s. Well, I haven't noticed them

I run losi shocks and 40w oil. I have a slight anti squat, or level. It will depend on how much weight the electronics are (one speedo doing brushed, or 2 speedo with brushless).

Thanks!
