GRM believes in us and what we do to publish a magazine about it, know what to test, spend the time and money to test in the hopes that you will buy a subscription, or at least that issue.
Sort of like me publishing free technical information that gets used by everyone in the hopes that folks will throw some business our way.

So I got to pull the front coilovers and check clearance on my NA, Keep in mind I have drift knuckles, I don't know how these will clear with standard knuckles.
To clear the sway bar and control arm (v8roadstet tubular arm, and fm 1.8l sway ) I need to run a 5/8" spacer.
I will need 30mm flares, and also I need to change the bolts on the sway bar brackets to something lower profile like button head or non flange head.
The bumper/fender tab needs to be trimmed and the brace that goes to the chassis removed.
Also the tire rubs the bumper wheel arch, I'm still undecided about running a splitter and air damn setup, so either the bumper will be trimmed or the air damn installed.
All in all not as bad as I thought. No real pounding of metal needed.

Per one of TR's higher-up's:
We (Tire Rack) received an update from Pete Calhoun (BFG Motorsports Marketing Manager) this week to clarify the situation. The revised tires will have a new part number, the speed rating will be revised from W to V. BFG is still in the pre-production stage for the revised tire and no "new spec" tires have made it into the market yet. The set that Andy H tested for GRM were a pre-production "Test Set".
7 current Rival-S sizes are planned to receive the update, 205/50r15 through 245/40r18 (all 3-rib designs) The wider, 18" sizes will be unchanged. At this time we do not have a firm ETA for the new version, but the indications are late summer for all sizes to become available.
You are confused. That aero-drag comparo was between the 245 VR1 on 9 and 10" wide wheels. Since the extra wheel width is entirely outward, the tire sticks out further into the airstream. That's why I love running dataloggers, 'cuz you find stuff like that. Surprised me how big of a deal it was.

Wannafbody lives in a state of confusion. I'm not surprised.
Emilio, was that data published anywhere? Curious how just a simple tire spat would do compared to a full air dam.
