description  When I built my Lunchbox I originally fitted oil filled shocks, then I changed my minds and went back to the kit shocks but was never sure of the camber angle that they put on the front wheels.

Of course, if you're using oil filled shocks then you can do this just by adding some spacers on the pistons.

It's simple to fix though, I cut 2 lengths of rubber tubing down to 6mm (I actually used the rubber tubing that came on the kit supplied motor).

The pictures say the rest though really, no more of a description needed, sorry for the indoor dark pictures!

Since doing this, I decided I didn't like the new angle on the body, so I filed down some broken body posts and used them as spacers on the front body posts, meaning the body is now back in it's original place

Yeah, oil shocks spoil the fun! To pre-load the suspension (to get rid of the camber) I usually use small cable-ties on the front rods and large ones on the rears. Another trick you may want to try is using a TL-01 servo saver, this preserves the steering geometry when the front hits the deck. LUNCHERS ROCK!

Nice touch, makes you why Tamiya couldn't work that out for them selves, as the camber I think wasn't done deliberately.

Admittedly, it does look cool!

but I love the positive camber! - these are not about handling!! (I'll expect a backlash)

I have got some more oil shocks on the way now, decided to go back to them. Will also add some extra bars to the chassis to stiffen it up a bit Got some more weights to go up front if needed, still want to wheelie, but not so much!!

I see you've added some tyre weights to the front end; one of the better mods I think Of course, you could do the same thing with the oil dampers, and get rid of the 'bouncy' effect
