Jason,

What size helmet do you need. I have an SA2000, full face, G-Force. Size small.

Graham

Graham,

I dont know what size I wear in g-force, but I know I am normaly larger then small. That being said, I found that I do have a snell helmet that belongs to my gf. its a hair tight, but I can deal with it for 60 minutes at a time.

if all we see is DOT, that is no guarantee that it is a quality helmet.



Kendt, From the clubs perspective, I cannot agree with this more. and even if you peronally know that a DOT only helmet does hold a higher quality, you still cant allow it due to the club having to set a minimum standard. Again, please dont think I was trying to argue that the club should allow anything with a dot sticker. I am arguing that DOT does not always = crap.

Take a look behind the liner of your KBC. I believe they have been Snell certified for quite some time. That might be why it seems better built than your Fulmer.

I don't understand you refusal to wear an open face for autocross. You are going no faster than you would on the highway and I'm sure you don't wear a helmet during your commute to work. Right? I switched from a full face M helmet to an open SA and am extremely happy. Sitting in line waiting for your run and sweating in your brain bucket is extremely uncomfortable. At least with the open face you can catch any breeze that might be blowing that day, or you can direct the air conditioning towards your face and cool off.

Just my $.0000000002



Todd,

I checked on the KBC thing. my old KBC has no reference to SNELL that I can find. again, if that helmet had not been wrecked in and the padding having become so warn that the helmet is too loose, I would still trust that helmet. My girl friends kbc vr2 does have a snell stamp on it (i didnt pull the lining to see if it was m2000 but I know it was not designed until sometime after 2005, so I should be atleast m2000). its tight, but it will deffiently get the job done and look "cool" while doing it... eh, who am I kidding, I HATE the graphics on that thing... but at 90 bucks for a close out helmet, how can one go wrong :mrgreen:

as far as the open face vs close face. It all really depends on the situation. I go up to the mnts without helmet in the car and will push it some. am I running 100%+ percent on an autoX corse... no. is there still a chance of me wrecking, yes. same thing with the highway... but I feel the likely hood of me spinning is less then on an autoX (which I have proven by the number of times I have spun doing autoX vs the times on the street, 2 times, both in the rain, and both driving the speed limit and not playing around).

Simply put, I do not feel comfortable pushing the car, or anything else to the edge (and beyond) my abbility in anything less then a full face. I am sure some of this is influanced by my time on a motorcyle, but, I simply am not. I feel too naked wearing a helmet without a chin bar.

If you want to talk pure comfort, I do agree with you about a 3/4 being alot more comfortable in a car sitting and waiting your turn. Now, if the rules allowed a 1/2 helmet, would you be comfortable wearing that doing autoX? I believe those helmets allow you to be even more comfortbale in the summer heat then a 3/4... though you are giving up even more protection with them.

As comfortable as my Impact Racing helmet is, I often consider picking up a second, open face helmet just for autocross purposes. I figure I'd be better able to see whatever cones I'm about to set on fire.



Karl and james. I think both of you are making the same point, I think a 3/4 is deffiently going to allow for more comfort, but less protection. That deffiently is a trade off that one has to choose from. I have never had issues seeing to the sides of below my nose in a full face. This could be a biproduct of car designed helmets vs motorcycle/street designed helmets. I am actually looking up which technically offers more side to side visibility, but I honestly cannot see the edges of my helmet when I am driving and dont understand how a 3/4 can provide more visibility. Maybe its a "try it to see" thing.

Also, in reference to visibility, Do you just turn your eyes? or do you turn your whole head (and helmet) again, I just cant see the edge getting in the way of your usable view if you are turning your head.


EDIT: Ok, I have not done an all inclusive search, with lots of flashy numbers. The only numbers I have seen is that a "standard" motorcycle helmet offers about 210 degrees of visibility. This should only limit you by 3% of your total vision. I have also found alot of talk about the differences between SA vs M helmets. The reason I dont understand how an open face can be less visible then a 3/4 is that M helmets are required to have a larger visitbility then SA helmets. Link to a forum that seems to cover most of what I keep finding. http://www.lotustalk.com/forums/f238/car-vs-kart-vs-bike-helmets-72506/

James, Kent,

Thanks for the clarification. I never knew snell{version} = m{version} If we go this route, I will likely be out the first few events until I can purchase a snell helmet. (far from the clubs fault... just sayin is all)

Kent, I realize we dont know each other overly well. That being said, I do find it annoying to have to put one on, but I also feel naked without it when I am running at 100% in my car, or any time I hop on my bike.

I do trust some DOT helmets. However, that is because some DOT helmets do exceed the min requirements set forth by DOT.


HMMMMMMMNN, excommunication worthy statement here?

Jason, no one here really cares if you plaster your cerebellum to the front part of your skull while in the pursuit of whatever thrills you derive from this brand of fun. but the rules of participation are non-negotiable. play by the rules or play somewhere else.

BTW, if Kendt were to ask...............

Brad Mackey had given me a used full face that has aged out of the track program. I was going to put into the autox loaner pull, but if anyone wants it, you're welcome to it. It's a Simpson full face w/ a SA 2000 rating. Size is 7 3/8. As far as I can tell from the pics on the simpson site, it's either a V-sport or Voyager helmet and white in color. Inside of the helmet is in very good shape. Let me know if you want it.

A consideration for the Full vs Open Face helmet - what were the safety systems in the car designed for? Was your airbag tested with a helmeted driver? Does that chin bar of a full face cause or prevent more problems? As far as I can tell, there's little evidence either way, but I'm pretty sure that the airbag wasn't designed with a helmeted driver in mind.

The types of impacts you will see on a bike (i.e. head meets road) are a good bit different than what will be seen in the car (head meets window, roof, steering wheel, etc...), so I don't think I'd personally compare the 2 at all -- though I absolutely agree that best protection on a bike is with a full face - I'd rather not leave my chin and nose spread across 100' of asphalt!

FWIW, I run an M-rated open face for AX, and an SA full for track (with full harnesses and HNR planned).

You have a bigger head than Graham. He doesn't have a need for a big head plus you have a lot more hair too.
