Chris I actually did do a bit of seam welding before I painted it white It was a pain to do as had to get rid of all the old paint ect. I basically just did around in my engine bay to stiffen up the struts and swaybar mounting and engine mounting ect. I didnt go overboard. My car has some cracks in the body nothing to major just the lead joins on the rear quarter to roof and top of front windscreen stiff susspension and circuite racing does it i have both my front and rear screen urethaned in to stifen the shell also teh 6 point cage makes a huge diference driving without either the strut brace or roll cage it feels very sloppy well compared to what im used too.
cya next week at the nationals (if its going)
Cheers Andrew
