I'm afraid i can't take the credit for doing those mate lol! The original turrets were cut out right down into the wheel arch then the new turrets measured/fabricated and welded into place, with the bracing to strengthen/stffen it further. I paid a lot of money originally to have them done but the company measured things wrong and they ended up sitting too high meaning the coilovers didn't fit correctly. Unfortunately they shifted the blame and insisted the coilovers were definately wrong, which they were to an extent but as they were refabricating the turrets they could have remedied the problem by adjusting the height of the turrets to suit. To cut a long story short i ended up having an engineer friend of mine chop the tops off to make them lower and redo the bracing to a much higher standard!
