Then a crush tube it is, but the roll-bar tubing wont crush, if you noticed in the first entry I had trouble with the guy who made the roll-bar, I asked him to make it out of 3 mm wall tubing, he made an executive decision and made it out of 6 mm wall thickness, yes that's 6 mm so the car has doubled its' weight and I predict having to build a f****ing wheelie bar for it. That is why I hate having to outsource things.

Just cut the suspension mount in half, make the crush tube a bit bigger than the tubing, bolt the suspension mount up to the crush tube so the spacing is set and then weld it to the chassis.

Roll-bar will be ok will just need to re-new the rear shocks every 12 month due to being worn out

What about these weld-on tube ends?
http://www.demon-tweeks.co.uk/motors...pin-connection They are used in rally cars to add bracing tubes to existing roll bars. Diam is 40mm.

Now that's a damned good idea Sylvain and the best bit is I can go and collect them as they are only 5 miles away from me.

it's not so much what he manufactured it's the fact he totally ignored me with regards to the materials. I requested 3mm wall thickness and he used 6 mm and it ways a bloody ton, and an aweful lot more work to drill through.

Raise the spring rate on the rear to compensate Arfon
