Rear suspension brackets
MikeRJ - 20/4/06 at 07:33 PM

Finaly pulled my finger out and finished the brackets for the rear suspension. Wasn't happy with the standard brackets as they were so unsupported, even with a brace at the back. This is probably massive overkill, and it's certainly not the most lightweight solution but it should be robust.

Need to turn up some spacers to centralise the rod ends and get everything welded etc. I think the holes give enough articulation, but will check when shocks are mounted . Hopefully have it on it's wheels this weekend and then I can sort the engine mounts out. More progress today than in the last 2 years I think LOL.

What thickness box have you used? Can't help thinking it looks a lot like 1.6mm. I'm not expert but i'd worry about the strength if it is.

It's 50mm x 50mm x 3mm RHS. Bloody hard work to saw...

Are you going to powder coat the chassis? Otherwise I would worry about getting enough paint in there to prevent rust forming.

With regard to cutting 3 mm, have you tried a 1 mm cutting disc in a small angle grinder? I do almost everything with them.

Probably not going to powder coat, unless it's cheaper than I think it is...

I have left the bottom of the box open to allow any water to drain out, and I will thoroughly waxoyl inside the box section to prevent rust. I have rubber boots for the rod ends, but am considering fitting some boots around the holes to limit water/dirt ingress which would make it much better than the book design in that respect.

I hace use the 1mm discs for a lot of stuff and they are excellent, but they are no good for making short/intricate cuts.

How many washers are ypu going to lose down there when you're spacing rose joints?

Going to turn up some solid spacers, can't be arsed fiddling with hand fulls of washers!

looks like a good bit of fabrication to me.

One question though - How will your panelling/bodywork fit around the extra width of the bracket? Or will it be concealed behind the rear arches?

I hope so! I had a look through the archive at several builds before I made them, and it looks like the rear arches come down a fair bit in front of the suspension brackets.
