Could be wrong but there is no requirement in the IVA manual for any roll bar to be fitted and it is only used (apart from being a roll bar)to mount the seat belt mountings,an adittion to Talons comment on the Blue books reqiurement's in motorsport is for a rear protection to be fitted, its a good idea to fit a rear bar to the Roadster rear stay's.

well just had a go at bending my rollbar... complete failure!!!! Packed it with wet sand, used a 50mm die etc etc

I was using ERW tube and I read somewhere to have the seam halfway between horiz and the bottom of the die. Tried to bend the tube with the rollers in nice and snug and the begger kinked staright in half like a coke can.

After much cursing and declarations of selling the stupid car etc etc I reconvened back to the garage looking at my 35 that I just put in the bin and thought well may as well try all other possible varients...

Tried it with the seam vertical and rollers untouched, kinked
Tried with rollers out on the last 2 holes (as I read that somewhere) seam horiz - kinked
Same set up but seam rotated to the halfway position - kinked
Tried with seam on the top - kinked

So I give up... stupid tube.... stupid tube bender

Not a good start to a day working on the car

If your using the open formers that come with the clarke 12t bender it does'nt matter what you do with the tube it will always kink or go flat. You need to use high sided formers like the hilmor conduit type, how ever the biggest hilmor former is 42mm. You still get minor kinks that are 1mm deep but can be over come with a little filler and paint.

well i guess that's a little comforting that I didn't completely screw it up but I think i best leave it to the guys with the proper kit

too expensive to keep experimenting, think i'll try and find someone local who is geared up to do this properly

thanks for the response

Only thing to remember is that if your seatbelts mount to any part of the rollhoop then the IVA man will want to check the construction and that the arrangement is structurally sound. Otherwise there is no requirement for a rollbar under the IVA.

I am intending to mount the seatbelt points in the crossmember, but it will be a solid fixing
