front chassis bracing
I was looking at the new dax cobra replica
and in that they have put a cross brace between the suspension mounting points
and one have any ideas if this would do any good if on a locost if tubes fu1 and fu2 where cross braced as the forces on the top suspension on one
side would be feed towards the forces from the bottom one on the other side.

Wil there be space in your chassis with the big engine for it??
Theres a thread on here somewhere with the best strengthening add ons..
I reckon it would help cos it would stop that part of the chassis flexing on cornering etc..

I've done the mods described and just looking at the front end makes me feel a bit safer (assuming it gets on the road)
I would also recommend to new builders that they fully weld in a steel floor and seat back. The flimsey Ali jobs just aint strong enough. If you want
more poke, use a suitable engine rather than break your legs for the sake of a couple of pounds in weight.

x bracing
Yes, it is a good mod and I think it is included in the later versions of my lowcost chassis mods (The above link is one of mine). I don't
emphasise it too much because of the engine clearance issue. I wouldn't want to suggest something that would get in the way of fitting an engine
for obvious reasons.
You can't really go very wrong with adding diagonals, V braces, welded in panels or X braces to most spaceframes as most them are not very well
braced to begin with.

Front Chassis Bracing
The Cross brace on the new Dax chassis is not for strength, it's part of their camber compensating front suspension setup.
i.e. If one of the front wishbones moves up the cross tube moves the opposite wishbone to ensure that both wheels stay parallel and thus has zero
effective camber change. Apparently it's a very complex system to setup (reading between the lines if not done correctly it will cause more
problems than it solves).
