There are many bonnet options available. Most any of the bonnets are offered in 2×2 twill or plain weave (1×1) carbon fiber, carbon kevlar (blue, red, orange or yellow kevlar), and can be either full carbon (exposed or ready for paint prep) or carbon on the exposed surface and fiberglass behind that or full fiberglass.
The following are pricing examples and the final price would be dependent on the options and style of bonnet.
MKI & MKIII up: full carbon, $325 – exposed carbon with fiberglass, $255 – fiberglass, $185
There are also different style options available, including stock MKI / MKIII, smooth, small scoop, or bulged. Pictures will be added showing the different options.
The vented bonnet was made primarily for mid-engine conversions, like Z Cars but will also fit on front engine Minis and can be made with or without the vanes / louvers.
