Hi, a very good model, very solid and quite easy to assemble. Compared to other models on the market, it is the most beautiful, cheapest and most robust that I have found, even ordering it from France and having to pay far too expensive shipping and customs costs. Fairly simple to assemble, it still took me a good day of work but no major difficulties encountered. Everything is quite well designed so that assembly is simple. I recommend GC Fabrications for its half hoops with an attractive price/quality ratio and I recommend BOFI Racing for its always fast, simple and reliable services as well as its well-stocked catalog of high quality items! I am finalizing the editing of a YouTube video which will explain in French the installation of this roll bar in my Mazda MX-5 NB.
