Do you mean like this:
Trimmed Hugger or this in carbon:
Carbon Shortie The OEM hugger cuts nicely and with a heat gun you can finish and tweak the trailing edge for some added detail.
I sourced the carbon bit from
www.valenceusa.com, a Ferrari supplier who are slow to move and pricey, but the product is top notch!
