Wondering if I should build in some anti dive?
How much are you expecting the front end to "dive" under braking? Is it enough to dramatically change the alignment? Make the car "squirrelly" under braking? My biggest concern would be toe change under braking. A big difference toward toe out will make the car "wander" or "hunt". Just what the driver does not need. Cars at speed tend to "skate" on the salt because of the low traction. Once it "wanders" or "skates" away from the driver, they are just a passenger . . . . . .
I, personally, would not worry about braking traction in dive on salt, the way I would for a car on pavement. I just don't think you have the same amount of traction.
Just my 2 cents, and I am not a suspension specialist. Perhaps some of the old hands on the board can comment in a more insightful manner.
