RS for life. (The car or me)
I haven't seen the article and probably won't. Motor Trend isn't on the top of my reading list. But when these guys and the Car and Driver guys came out to ice race with us in the past; it became clear that their expertise is in writing not driving.
Who drove the cars?
What track?
I am curious about the fact that the RS was understeering at the track as one person stated and then oversteering at another part of the track.
Either way, I enjoy my naked, I can lock up the wheels when I NEED to RS, in the snow, on the pavement, and through the gravel.

From what I understand 1/4 drag racing aerodynamics, really don't become that noticable (ie measurable) until trap speed of over 100mph. I am sure you can measure the difference between and Evo and a Mac truck, everything similar (engine hp/tq cuyrve, weight), but I don't think it would that notice with a buick grand national and evo (given evrything else equal)

I picked up the magazine and read the article last night. Very good stuff. I understand what caused the RS to brake worse than the GSR and MR from 100mph, but I'm still confused what factors caused the RS to lose ground after the initial stage of the course.
Do any of the people in here who have track experience behind the wheel with both the RS and GSR/MR agree with the magazine's opinion of the RS having more oversteer? I refuse to believe the spoiler or Vortex thingy have that much of an impact...if any. If they do BMW would be slapping them on their M5 and M3. Those 2 cars are built to rule the autobahn where speeds like 120mph are nothing.
EDIT: Ooops...I meant oversteer, not understeer.

The cars were all tested by the same person (Chris Walton) for all tests as are 95% of what we test. They were tested at Streets of Willow @ Willow Springs International Raceway in Rosamond, CA for the track testing protion of the comparison and Californaia Speedway in Fontana, CA for the instrumented portion of the testing and I can guarantee you that none of our California test team has done any ice racing recently, so it wasn't us you claim to have witnessed.

We could do this test again with three different Evo's and the acceleration numbers could all be close but different depending on how strong the engine is, in which Evo. The track results would likely be the same, since the weakest engined car in this test finished first at the track.

There's a reason why all f-1, rally, GT, and to a lesser extent NASCAR autos have spoilers and air diverting effects...
If you need more proof, check out this baby
