We know, we know... you've already seen spy shots of the upcoming Ferrari F430 Challenge Stradale. But we can't help but get excited for what promises to be one of the most tantalizing applications of the more-power-less-weight battle cry. We've seen what an improvement the formula made to the F430's predecessor, the 360 Modena, so stripping weight off the already faster-than-spit F430, tightening it up and squeezing a few extra prancing horses out of its screaming powerplant should make for an even hotter ride.

To recap, the 430 CS is anticipated to strip an additional 100 kg or so off the curb weight of its "ordinary" sister by stripping out non-essentials and replacing some of the sheet-metal with carbon-fiber body panels, all while boosting output by an extra 20 horsepower or so thanks primarily to a freer-flowing exhaust system with tips placed higher in the rear panel, like on the previous 360 CS.

These latest shots of the 430 CS test mule, which you can see in all their glory by following the link, were snapped at the Nurburgring and show a revised front end with what look like flared nostrils and a track that has apparently been even further widened over the already broad-shouldered F430. Slight changes, to be sure, but the fine-tuning of perfection has us eagerly counting down to its anticipated debut at the Frankfurt show in September.
