you want 33.7 x 2.6 for the bush tubes

and 25 x 2.5 cds for the wishbones

Some useful discussion from the RGB racers.

I'd go with 25x2mm-1"x14gauge minimum for the lower arm/wishbone and 19x2mm-3/4x14gauge for the toparm/wishbone. CDS cold drawn seamless is best but ERW is cheaper.

With the kind of questions your asking I wonder if you are better buy some thing off the shelf.
And if you need a spare you can replace it easy.

Bones get bent ......with the state of the potholes it aint getting any better....You only have to be unlucky once. Or in a good buddys case 3 times

Cheers guys for your help, mangogrooveworkshop i'm making them cus i'm rose jointing the outer edges for setting the car up for hillclimbs and sprint, car wont be used on the road,

I know the roads are harse on a car, i'm also going to kake a jig up and once the cars going make a complete spare set to have with me at meeting, the way i drive i'll need them
