if you are mking a 4 link for example and there is no motor or gear box how do you set your pinion angles
or if you have a box in and your making 4link etc how do you know your pinion angle as the vehicle isnt sitting on the ground etc while you weld it all up and set it up

What I like to say to the buy a GQ thing....

X2 to slunnie's suggestion.
Adding weight is a guess too. Desired ride height isn't a guess as it's the measurement the whole 4 link was worked out on. If if sits higher/lower once complete that's then a spring issue but the pinion angle needs to be right at ride height.
Have a look at the Pirate buildups - they are all either built at ride height or full compression after angles at ride height have been confirmed.

Bunky?
In any case, no, I'd put the car on chassis stands at the height you want it, hook up the links, adjust pinion angle, then calculate/trial and error springs and/or weld perches on to suit the height you;ve worked out the links for.
Remember, your suspension design only works for one height. Lift or lower the car from design height and the geometry gets worse (although lifting it normally makes it worse than lowering) - that's why it's critical to make it work at desired ride height.

i am going ot face the same problem but with wider 60 axles in a 40 series. i was going to put it all together with the ubolts and no welds - weight and shape of perches with the u bolts clamping it will be good enough whilst its in shed and rolling down driveway. once nearly complete, shaft length finalised and weights pretty much kerb weight align properly then weld tight... would this work for you?
even when you spell out commonsense to the RTA they still ignore it!
