Got a bolt on OMP strut brace for my mk2 fester which is bolt on but is there any reason not to weld it on instead? Not to bothered about removing it later on any views?

 

you won't be able to change suspension top bushes or remove nut holding strut into strut top may need a bigger hole in the strut brace to get a socket in, you wouldn't be able to get a spanner in and an allen key to hold strut either.
really thinking about it, don't weld it in.
what you can do use use nutserts, that's what i did with my mk2, i used M8 nutserts, hard to fit the bloody things, but hold it very tight.

 

Why not just get some roll cage tubing and weld between the struts? Better than the (normally) flimsy strut braces, and will have the option to use it for harnesses?
