I caught a lot of flak for body mounting/cutting/pinning recently at a big race.

 

I have a new chassis that's much shorter than anything else I have, and I didn't cut my body properly to account for this. What I ended up with was a body that had to be moved forward to clear the rear wheels. Well, I do know that that's not right. So at the track, one of my friends offered me a body, and I tried it and it was better. It was still too long for the chassis.

 

A number of folks had their 2 cents worth of advice, much of which was helpful, but was pretty ill-timed for me.

 

So here goes my questions:

- Many of the racers suggested a 32mm dimension. I am not 100%, but I think this is the height from the back edge of the body to the bottom of the cut. Can anyone clarify that?

- How long should the body be in relation to the chassis? If you give an answer related to chassis length, please indicate what you're using for "length" of the chassis.

- If we know the height and length, then anything else should fall into place.

 

I am not looking for instructions on winging or mounting, just for help with measuring / doing this the right way.

 

Thank you in advance

Mike

The 32 mm is the height from the rear edge of the body to the cut as you described. You must be building the body for a C can, a cobalt class(c12, 27, etc) would be lower.
As a rule of thumb you measure the length of the chassis which is from the center of the rear axle to the center of the guide flag hole then add one inch. Cut the length off of the front of the body. These are basic rule of thumb measurements. There are so many variables when building the body especially the class that you're building for and the track you're racing on.

I feel your pain Mike. I raced GR27 from 1994 till 2008 and got the same kind of response to my bodies.  I finally gave up and used Beuf bodies.  Wing car bodies are kind of a black art.

I will look tonight, but it's either a Koford M530T or M530R, which are 3.995 and 4.070" respectively according to their description. Best bet is I will look tonight and measure.

  The 4.12 car is the most popular here at Buena Park, so this is from experience.

 

Cut the body 134 long measured parallel to track surface by 32 mm tall at the rear edge

 

Cut the side dams to 129mm from the front edge of the rear wheel arch to the front of the side dam. this will put the front edge of the guide right at the front of the body, meaning you will have to carve away about an 1/8 of an inch from the top of the guide and shorten the guide clips accordingly. That will put you in the game and it's just a matter of tuning the dimensions to fit your track and diving style.
