The last Newton I studied came in a yellow package and promised to be a healthy alternative to candy.

Regarding the wing, I've had both versions on my car. The mechanical spoiler is a neat design trick, and the act of it deploying as I accelerated down the on-ramps would gather the attention of many. Children LOVE it. I've seen folks of all ages making the face, and pointing as I sped away. I would give a wry smile and carry on about my way.

The SRT spoiler gives the car a "balanced" look, adding much-needed visual weight to the rear, at any speed. The SRT wing is a thing of beauty, especially in person.

Some notables:

• N/A wing (and assembly) is significantly lighter. It also provides but a fraction of the downforce.
• SRT wing gives the car a much more planted feel at speeds north of 100. While the N/A wing stabilizes the car, the SRT wing glues it to the road.
• Both are equally annoying to clean, in their own special way.
• The amount of road dust recirculated on the back of the car is MUCH greater with the SRT wing. A small price to pay for the amount of downforce you gain.
• The attempts from others to race you at a stop light are cut in half, with the larger wing attached. Seems the chil'ren are paying attention to the SRTs on YouTube...
• Mileage with the SRT wing drops by 1-2 MPG. I regained that by lowering the car, but still...
• At speed, there is a slight "buffeting" noise from the wind seeking a path around the wing, that the N/A wing didn't have.
• The SRT wing adds mass at the very edge of the decklid, making an accidental "slam" a frequent occurrence.

That's about it. Real-world, the SRT wing is worth it's trade-offs. The N/A wing is perfectly adept at keeing your car from doing somersaults at reasonable speeds (<140). The SRT wing gives you assurance in the fact that you're going to be planted at ANY speed.

Now, I'm gonna go buy some Newtons.

Cheers,
