    as far as benefits, pretty much anything anywhere in a rolla that stiffer is goin to be a bonus (as long as it doesnt add too much weight). a half cage made a huge difference to the handling of my rolla when i had it.

    the main seams are the ones which are under the most stress, and connect to the more important parts of the car. i.e strut towers, wheel arch's and chasis. weld these to each other and you should get some positive gains from them.

    i recomend searching through old scholl rally builds and such where this was done a lot and see what they did.

    in reguards to legalities, if the engine bay is painted i challenge any cop to pick out that the bay has been seam welded. i dont think its illegal any way, just say you bought the car like that, and try to talk your way out of it if they pick it. i talked my way out of a weber carby, gatorade being used as a catch can, and twin tips poking about 1/2m out the back of the car. just depends who you talk to...

    Considered adding more meat to the chassis? This could help stiffen up the chassis without a rollcage. The mid section seems very weak and i've seen countless chassis bend at almost identical areas. One of the club86 videos shows bracing done on tsychia's car which seems like a good way considering he thrang'd his car alot. Here is an example of some1 doing the same, believe I saw it on the EU forums.

    i eventually want to run rosejointed equal length rear end in my 86 track car and i think i read i'd have to seam weld the chassis is this correct?
    would a full cage do the same job?

    Ive had my engine bay seam welded (Cheers Dimsum) and a half cage installed (and again) plus suspension completely redone since having my 86 off the road.... I cant comment on the improvements as I haven't driven it yet, but I suspect it will be in a whole new class than what I remember

    I really wonder how much of a difference seam welding makes, I don't think people give spot welds enough credit

    Lots, the proof is in the pudding. People have been doing it for ever, in my previous and current gravel car you could notice the difference with the engine bay, strut towers and around the rails done.
    Personally I think it's well worth doing, and you would never have any problems with the fuzz, as long as you re paint the welded area.
    I got nothing.

    yeah we all know it does something but I think it's more the icing on the cake than anything big, just my hunch anyway
