Air Dam/Splitter Questions


Wink

Recommended Posts

When going through tech at Barber last month, Dan mentioned to me that next year (2018), we would no longer have to claim the roll plastic, we've made our air dam with, as it will be considered part of our splitter. I haven't been able to find any update in the BCCR touching on this. The plastic is 21 points, I could use elsewhere. Just looking for some confirmation.

In the interest of brevity, they omitted some words from the rule, but the idea is that you get the splitter and associated stuff for 10 points. Splitter not much good without air dam or adjustment linkages, so those are included.

Same with 10 pt wing.. also comes with mounting stuff and adjustment stuff. 

 

Although not written in the rule book, a rear diffuser is also 10 points, and a flat belly pan is 10 points. I recently asked Phil and Mike to include these items in the rule book.

That's pretty much what mine looks like.  WE claimed 10 points.  However, it looks like you have a splitter too.  I think that is an additional 10 points.  I could be wrong...

Roll Plastic 3pts/sqft 

 

Its just over 7 ft around and 14'' tall

Yea, I am saying that ours, that is roll plastic, was claimed as "air dam 10 pts".  Tech was fine with that.

 

The splitter sticking out of the bottom may be another 10 pts.

@Mopar 63

 

Is this correct?

 

10 point splitter

10 point wing

10 point diffuser 

10 point belly pan

Then diffusers and belly pans are valued by square footage of material used, correct?

 

 

That was always my interpretation. Main reason I hadn't even considered a flat bottom

whoa there buddy.  I didn't say that!  :P

 

I believe any individual aero device is 10 pts as long as it isn't made out of unobtainium.  I know the rulebook doesn't say that exactly, but that was how I understood it from some earlier threads.

 

oh yeah , 10 point spoiler....

 

So, to reiterate...  On the front of the car.... 10 points for a splitter or an airdam.

 

Rear of car: 10 points spoiler or wing or diffuser.

 

Middle: 10 points undertray.

 

This is my opinion.... But, Tech has agreed with me on the airdam and spoiler....

So are you saying that if you have an airdam and put a lip on the bottom, it becomes 20 points total?

 

@red0 This is why I am pushing for the rule to be inked... if it isn't in the rulebook at 10 points, then any intelligent person would conclude that the point value of diffuser / bellypan would be determined by material and surface area.

We may add it in the future.
Its 10 points as long as it doesn't go past the rear dif. Same as your front splitter (10 points) and it can't go past the front spindles.
If you cover your center under carriage its also 10 points.

If this were true, would there be a really fast E30 with all of the aero and still 500pts or less?

 

Is it just me or is a direct correlation to efforts for brevity in the rules and how confusing they are to try and understand???????

Things should go into the BCCR so everyone can know and understand the rules.  Or, put them on the tech sheet.  This would save to poor tech guys hundreds of emails per year. Or, save them from explaining the same thing over and over a hundred times a year at different races in tech.    It would also help new teams from having to guess.  The rules need to help save tech from headaches, not invite them.

My understanding was that a combined airdam + splitter like the one in the first post or on the GWR e30 is 10pts total, not 20pts.  But like with every other rule, we probably all understood it differently and need confirmation from @Mopar 63

 

We have a combined splitter and airdam like the Miata pictured and have only ever paid 10 points total for them.

We have been told that same thing in tech in the west.  Splitter AND/OR Air Dam is 10pts total

Well good, the car isnt at 500 yet anyway, but hearing the flat bottom will only be 10, instead of by sq ft, is great news. 

 

However I do feel, there should be some aero clarification in the BCCR, but grey areas seem to be the norm, as the series grows and cars develop.
