TOPIC:

I have the last few weeks been building some Group C chassis, and by doing so, I have not found one practical use for the A3 parts mounted to the chassis.

Can anyone help me figure out what it's for??

If you put a screw through it, you can limit (and adjust) the maximum roll of the chassis.

Edit - and influence understeer/oversteer...
I put some titanium screws in my C11 so it'll give some nicely coloured sparks when hitting the tarmac.

I think it's about the maximum angle the T-bar can make compared to the chassis...
Pretty neat feature actually. The only car that I've seen so far using something similar is the F103 TRF.
Although there the approach is different and the angle of the T-bar itself is limited by screws MA2 in the battery tray :




Btw - if I am correct less body roll will give more oversteer...
And more allowable angle will shift the characteristic to understeer.

Another edit of course - I think the official term for it is tweaking...

Mmm... tweak would refer to the weight distribution according to this article.
Although the previously discussed could be described as such.

"Tweak" is also linked to coffee, a small mountain town, & underpants gnomes (If you've seen that episode?)

I thought I saw 'em all (several times) but I can't seem to recall this one...

Those tabs are for a under cowl that was never made.It has nothing to do with tweek. I talked to the Head of the direct drive chassis cars and that is what he told me.

Oh well, if that is true then they've found a new purpose.
Seem like strange spots to attach an undercowl though...

Rakuda, welcome on the forum!

There are two more screw holes in the rear for the plastic tub that hold the rear of the undercowl on.

Why would one want to attach the extra plastic bits though when there are perfectly fine holes there already that will match the shape of the chassis better and that would also be a more stable connection?
