I'm hesitant to be "that guy" regarding this, but I'd like to get some insight from the guys here regarding flares. I'm not in prod currently but have been toying with the idea of jumping in. My intent is not to stir the pot, only to avoid a sh!t show at tech should someone interpret things differently.

The GCR states The flaring of the exterior contour of any wheel openings may not alter the basic body configuration

That said, what are the thoughts concerning box flares? Not trying to pick on anyone in particular, I understand he's a long standing prod member and champion, but I'd like to cite Sam's TR6 as an example. In my mind these would be deemed illegal as it does drastically alter the body:

"may not alter the basic body configuration" leaves a LOT to interpretation...
The way I see it (and I'm just an average Joe), if it still LOOKS like the car, then voila. those crazy squared off DTM box flares? no.. but something like what you've pictured or the widebody kits ubiquitous on an RX7 or Miata? sure-- they still look like the original car but with a little more curve. That's my $0.02.

I had similar box flares on my Turner and never had any issues. The main criteria, as I understood it, was that when viewed from the side the wheel opening appeared to be the same as stock.

The wording of the rule is really clear.

"The exterior contour of all wheel openings may be flared. The fender/wheel opening or any
other part of the body forming the wheel opening, when viewed from the top perpendicular
to the ground, must cover the portion of the tire that contacts the ground while the car is at
rest. The flaring of the exterior contour of any wheel openings may not alter the basic body
configuration or change the wheel opening size, location or shape when viewed from the side.
"

The last bit is why box flares are a great solution that meets the letter and intent of the rule.

The last part of the reg addresses the opening size of the fender. When most older cars came with 13" wheels and now run 15' wheels, all the fender openings are now larger to accommodate the larger wheel.
What is the thought on that?

I don't see an allowance for a larger opening.
I also think a smaller opening might be an aero advantage.

I'd think the same thing.

99 miata from the side:

Matt Reynolds multi-time champ car, been through runoffs tech shed more times than I've raced:

Looks the same to the tech guys!

SORRY this isn't meant to pick on Matt OR the tech guys.

I just bought some bolt-on flares and called it good. I think the intent may be pretty hard to get into the rulebook.

Just don't cover the wheel opening.

opinions vary, but I think that's from when he got brake checked mid-turn by some dude in a Datsun and it cost him a runoffs win..
