the way i see it is that the chassis is just a frame, its the suspension mountings that are important, iv just started welding my chassis and am leaving the suspension mountings till last, they are tacked on for now but once the rest of the chassis is done i will tripple check that they are in the right place and aligner correctly then fully weld them on...

this way i know even if the chassis is slightly out that the suspension will be bang on (or as close as possible on a hand built car)

I agree with Jake here. However I am not even tacking my suspension brackets until I have fully welded the chassis and any movement(hopefully minimal) has taken place. That way I can be sure even if the chassis is distorted slightly the suspension brackets will be correct to each other and our datum (the surface table).

i agree with that to a point but having a really accurate chassis is always better. i did exactly what Ronnie described. my chassis was that good that i made and bent the side panels cut all the suspension holes etc out of the book and they fitted and lined up with the chassis perfectly. the thing that made me laugh is that when i told chris gibbs he informed me that the cad drawings for the side panels were never made or tested for fit

Naaa I have a direct line with the fella, it helps to know "where" you are going when time comes so I do my bit to keep in with him......

indeed it is, did a bit more welding on mine this afternoon and had a good measure to see how distortion had effected it, the only thing i have found is that BR12 has lifted a little (under 1mm) so have fixed some old wall ties to the table hooping over the bottom rails to keep them flat.
