The gap around the headlights was checked by tech at the national in Portland last week. I know I've seen this rule before but I can't find it in the GCR now.

Does anyone know where I can find it?

Thanks,

Ken

I don't know, but if 6mm is the rule, I need to widen my gaps [Smile]

These cars are going to start looking funny with folded up side mirrors and 5mm gap at the top of the left headlight cover...

I believe its from the FSM. Front bumper cover/hood gap is 5mm +/-1.5 and the hood/fender is 5mm +/-1. The gap around the headlights is not specified in my FSM.

They do get picky about the flush headlights once in a while. I was talked to about mine once last year. I don't think they really know what to look at on a SM so checking for flushness gives them something to do while they hold us in impound. They keep telling me my car is way overweight on the scales. I keep explaining I have a 1.8. When I drove Terrell's car I asked them what it was supposed to weigh and nobody knew.

Keith,
This my favorite conversation while on scales [Smile]
Steward: "how much are you supposed to weigh?" Kyle: "What do I weigh right now?"
Steward: "2274"
Kyle: "perfect, 2274"
Then I drive off.
At last years Rose Cup, I think they had a sheet with a diagram of the hood gap/headlight gap rules, according to SCCA, it was a supplemental diagram for the GCR. I would assume it should there this year.

Whoa, hold on there pilgrims [Smile] This used to work.

I was dq'd last year at the Rose Cup for being underweight. Seems that some parts that fell off the car were not put back on [Big Grin] If our stewards are good enough to take the time to weigh, then we should at least get it right.

On my list...

I saw some MAJOR headlight gaps this last weekend at Blackhawk, and was wondering if there was an "official" rule...

For the sake of a newbie (me), what is the advantage, if any, of larger headlight gaps? Additional airflow into the engine bay? I'm just trying to understand why it was enough of an issue that it had to be addressed in the rules.

Cr@p. I've got a banged up front and always have a gap. Now I've got to add body work to my To-Do list.

Kyle, that's what I was thinking. If tech has something they're using, It should be in the GCR.

They had the same sheet last weekend, but I can't find it anywhere.

Ken,
I remember some bickering about it being thrown onto us at the last minute and that we had never seen the diagram before. They then told us we could get copies of the diagram from them during the weekend and/or it would be on the scca website shortly... that was a year ago.

I was tech'd by Runnoffs crew and they measured the gap. I asked the reason and was told that some enterprising racers have used increasingly generous gaps (intentional) to increase airflow into the area of the intake. On this basis I am fine with making sure we all comply for performance equivalency (I had to modify my hood attachment).

There is no reason to have this gap listed in the GCR. If every detail of car spec of every car in club racing was listed the GCR would be - well - very big. This is covered perfectly well in the FSM.

Hi Craig, I know the reason they're checking it, I just wanted to see where they were getting their info from. Never thought to look in the FSM. Duh!

Thanks!
