Please do nothing rash before seriously considering this.
My roll hoops are from a Mazda MX5. They cost me a measly fifty quid because there are far more Mazdas on the road, ... more cars, more sales, more competition, more choice and lower prices.
I had to fabricate brackets and buy the stainless pins (that Pendragonfalls also did not receive) but for a semi competent person this is not a problem. If anyone needs help on the design of the brackets required I can forward an AutoCAD drawing that I made of mine, which may help.
My bars are 60mm diameter, so much more chunky than pendragonfalls bars, and without offending anyone I believe that they are better looking. Just my opinion. Don't beat me up.
All for fifty quid!
If you think about it virtually all cars are about the same width, all seats about the same distance apart, and therefore all hoops will fit reasonably well. At fifty quid I took a chance on them fitting, and they do! I had just missed an identical set that went for £25 so was gutted to have to pay fifty! Trawl e bay, buy a bargain and look better ....... what is there to think about!
