MTS,
Above and beyond just "looks", perhaps the most important thing for you to consider when choosing a body kit, is the overall quality of product. Take it from someone who has researched and inspected virtually every aero part known to mankind for the 986 boxster. Regardless of price or prestige, many of these parts, particularly the fiberglass ones, require a tremendous amount of "tweaking' and fine detail work in order to achieve an outstanding final result. Despite how pleased I was at the conclusion of my Hamann body kit project (and I should be since it won 2 best in show awards) , initially it was a nightmare . Indeed, when I first inspected the parts I was convinced that some kids at a vocational school in Germany had made them ! One would think for the price that I paid and the prestigious name behind them, they would have been "ready to go" right out of the box. That was clearly not the case. Again, the nice thing about the Ruf bumper and side skirts is the quality of the material and the excellent fit.
p.s. Here's some photos of my vehicle.
