Right then guys almost finished respraying, i've put a fair bit of time into this car now and i want to make it better and better, so i came to the idea of a roll caged (yes it is a 1.3

)! I'm going to gradually kit the car out with uprated brakes etc so i can eventually stick a valver in when insurance comes down a bit.
I'd like to try and build a custom 4 point with my mate who's an apprentice at his dads steel works firm, he said we'd be able to use all the equipment to bend weld and bash one up! probem is i dont know where to start? i've had a look at off the shelf 4 points and they seem to have the front section behind the seats bent into a U shape and then diagonal supports going down to the rear turrets or just below is this right?
has any body got pictures of thiers fitted? i'm looking around for ideas and patterns at the moment as i need to do a more research before taking the plunge. also would it need to be approved if its only going to be used on the road?
cheers guys
