Bonnet lifters

I'm trying some atm, still unsure if I like the look or not I just pressed 2 m6 nuts into an m10 nut and then drilled the threads out of the m6 nuts with a 6mm drill made four of these and fitted longer bolts, bonnet locks down and releases perfect, it's only a small lift though so it looks quite subtle
 
I'm going to put a washer at each side of each nut that will give it 13mm lift at the rear if I like it I'm going to make my own spacers from round aluminium bar and get some high tensile bolts to keep it rigid and secure
