The rules say that the body must be mounted on the trim lines. I guess I am asking what is the legal trim line at the rear? On the PF COT at the rear there are two lines. Will the bodies be required to be cut to the lowest line or can the body be extented below thoes lines? Or trimed to the top line?

Mounting question #2: Does the body have to be mounted in the center of the front wheel openings or are you permitted to mount it forward?

you won't be able to move it far if you plan on using them side dams on the wing... on a protoform body that is.

the body must be mounted in the center of the front wheel well.

I've got a question pertaining the mounting of the cot body. I've mounted the body and trimed to the corrects lines on the pf body, when I measured the roof height it was almost 4 3/4" tall, and the hood was over 2 1/2. how can you reach the minimum if the the body has to be cut at the trim lines? I;m not looking to slam or rake the body either but if I cut the splitter down to the min. then the sides get cut at an angle and not necessarily on the trim lines anymore. Anybody with some advice or knowledge would be appreciated, I'm trying to get this done for the weekend, thank you Jason

I went by the height requirements and the 1/8" minimum splitter rule. I think that gets you where the rules intend you to be after all that was what was stated. In most cases that is under the body lines but a few spots it was over it.

My front body posts on my 10R5 are LF 1.68 RF 1.70 so there isn't a whole lot of slam. The nose looks like a snow plow. :freak:

I have my chassie ride hight at 6 mm with 2.25 tires and the body trimed on the line and 3/16" spliter. The top hight is 4.625" amd the hood is 2.7". Remember, just like the real cot these have a tall green house (top and window section). There is a small rake from back to front. I trimed the rear to the bottom do not paint line.

I have a wing question. There are three lines on the wing top. I think on the real car they are called a "wicker bill" and are used to add down force. Can any of thoes be trimed?

Sorry for so many questions. I just do not want race day problems.

Larry B,

In the updated TOUR rules, they say you can go no lower than the bottom line. Alan Behler suggested that you cut down the side and bend it instead of totally cutting the lines off. I believe there are three lines.

Dang Larry... that's almost 4x4 territory!!!! LOL

I set mine up with 5.5mm ride height and 2.15 tires. The hood is about 2.7 and the top is about 4.5 - 4.6ish. This gives me room to go down to 2.10 tires and still be legal. You're right about rake.

Did someone say Baja racing. lol

Bill, looks like the Cot rules are working. I was watching the cup cars at NH this afternoon and working on my new HD4 car. Our wings (PF) are a bit higher than the ones on the cup cars, But it is the same for all of us. Not trying to start anything here. Who knows??? we may need that wing. You know what they say "plant the rear and make it steer".

I do hope we can get OEM wings so we may use the different hights for tunning. Most of all I just want to get back to the track. See you soon at Rosewood.

I hear ya dude... can't wait to get back on the rug. The COT bodies are hot and I think the 13.5 class is going to be a lot of fun.

I actually used superglue... thought about the nylon buttons but didn't have any to try out. Might be needing the OEM wings if that don't work out too good.

Anybody want to post a picture of how they got away with lowering the front end to the min. 1/8th" splitter and still have the sides cut on the body lines behind the front tires? I've asked this question a few posts back and never really got a straight answer. I would like to know before I have to paint a new one because I cut to much.

do you have to use the side dams that came with the body? Could you use lexan cut to specs? The ones that come with the body seem warped

I worked for the better part of 3 hours to mount the body getting the trim lines to the chassis hight, before I cut anything. I only trimed the spliter to 3/16". I also round the corners of the wheel opening (about 1/16" ) to keep from cutting the tires. After mounting, I also use a flat sanding board to square the body bottom up sideto side.

The next one I mount should be a lot easier sence the body post size wll be set.

I don't think that you literally have to cut the body on the line, you just have to follow the 2 1/2 at the center of the hood and front tires and the 4 3/8 at the roof along with the 1/8 minimum splitter. They are not going to tech the car with body lines they'll do it with height and clearance.

At least that's how I'm interpreting it.

Not sure about that but I would assume that it must be from the original wing or from the OEM wing that that manufacturer makes... could be wrong... definitely one that the TOUR board would have to rule on. :wave:

Here's a picture of mine... not sure if you can tell the body lines or the splitter height or not but I went strictly off the height requirements.

You can see that the line on the side has a little bit of rake from front to back.

Bill, you are right about the 4 3/8" at top and 2 1/2" on the hood. But,,,,, this is in the rules (INTENT of the Rule: Cut the body on the body line and don’t rake or slam the body.) I could drop my body a ton to get 4 3/8" on top. We need a comfirmation on what they will check.

Why would we need heights if we were only to trim at the line? That statement is just what it is... intent. Truth is you can't slam that body anyway, at least not that I see. My body, holding to the height requirements doesn't have a whole lot of front nose dip which would be the aero advantage, and there's still a lot of travel room for the front tires. Besides that if you took it at cut lines only, then the protoform body and mcallister body would have to be identical and I don't think they are.

Another point is that if you use cut lines only then there really isn't any need for height requirements.

Maybe we'll get some clarification from the guys on the board and they can help clear it up.

09-21-2009, 05:55 PM
If you have the correct hood height, the correct splitter height and the correct roof height, should it matter where the cut lines are as long as the body isnt scuffing the track? It shouldnt be that important.

I agree fastforward, but i run big cars to and if the rules say one way and then the rules say i.e. cut on the body lines then all of a sudden its found to be illegal, just want a clarification because the rule is unclear as to which you can do, meet body height rule or cut on body line. It may be stupid to worry so much about this but I don't feel like buying and painting another body because I trimmed above the body lines.

Alan Behler

ok guys here are the golden rules for mounting a COT body

1 mount the body in the center of the wheel well provided in the body mold

2 the splitter can be trimmed to 1/8 inch

3 the hood can not be any lower than 2 1/2 inches at the wheels

4 the roof may be no lower than 4 3/8 inches

5 the back of the body must be left in and on a protoform body it still must have the protoform mold in the back.

the mold lines on the side are a reference point. as long as you meet the 4 and 3/8 height they do not matter.

steve and i have gone over these rules. so if you have further questions go ahead and ask

09-21-2009, 07:30 PM
I cut the body at the line, cut the splitter to the minimum, mount it, then trim to fit. This leaves an ever so slight amount of rake in the body. Now, since I race with Steve on a regular basis, he's seen my car and had no issue with how anything was setup or mounted on the car.

might want to add that the protoform logo has to be intact in your rules page cause i already cut mine out :confused:

Then you cut it well above the bumper line.

Alan Behler
09-21-2009, 07:34 PM
the trim line in the back of the body is below that molded protoform
so yes it is the rule in general

this coming weekend will be the first for alot of guys trying the cot's. im curious what the thoughts will be on it after this week. i personally have seen guys turn out likeing it alot after trying it a night of practice. Danny Ost was fairly happy with his the first practice night he tried it. i like mine thats for sure

All I can say about the COT is this... last night I was over a lap ahead of the track record, set in February, the second time out with the body. Unfortunately a lap car didn't give me room to pass and I ended up getting turned around, and I still only missed it by a tenth.

No complaints here.
