Which body to use??

With the Shepherd the bost posts are set, so does it mean we have to standby with two bodies (one set forward, one set back) for race tuning? Or shall we set the body to 14mm from the tip of the bumper and use the gurney wing to adjust for downforce/traction/balance?
I have two uncut bodies so i'd like to experiment

14mm is WAY too far back for a Shepherd. Needs to be 18-20mm.
Often what I do when trying a new body is I will go ahead and paint up two, mount one the way I think it needs to be but leave the holes uncut on the second. If the car seems pushy, I can cut the holes in the 2nd for a more forward mount. Too twitchy, mount the 2nd back more.
2mm can make a BIG difference.

What I did was put the carbon front body mount left the stock body post pushed them as far front as I could then put the body 12mm from the front bumper with the LTwieght and it handles like it is on rails full trigger none stop but when I put the regular wieght body it will not handle it will push in the corner.

My car turns like all get out and is still stable at 20mm with the wing up. It's pretty darn amazing actually. But then, I have always liked a body slightly more forward than most people. Doesn't matter what car, track or body, I always seem to be about 2mm forward of everyone else with the same combo. It's just what works for me. I can get stability from other areas.

i am going to give it a try, i still have a P909 unpainted to try it on.
thanks guys, learnt some more about body mounting

if you mount the body too far front, yr front wheels will be rubbing on the shell during a turn right?...
#23
The rear wheels on my vector does scrape the TOP of the body though. must be getting a lotta downforce there
#24
do you guys mount the body as low as possible? i mount mine with the front edge of the bumper touching the shell...
maybe that explain why the front wheels would rub on the body when turning, if i mount the body too far front.

Yes, at least on the Shepherd the front tires will rub on top if you go really far forward. 18mm seems to be the limit with the front arms back, 20 if they are forward. Raising the rear with the Shepherd extenders or other methods will help.

does raising the rear with the extenders have the same/similar impact as raising the gurney strip? more rear traction and thus pushing...
#28
When you raise the gurney (thanks for using the right name ) you also move it back, which moves the center of pressure back. Raising the body doesn't really change the center of pressure much, but still increases downforce.
