Now we get into deep water. The control arms do more than you think in relation to design, typically seen on race applications and their mounting points.
Anti-dive is to lessen how the forces typically transfer to body roll, and transfer it through the control arms and spindles instead of the body roll path. The trick is to keep wheel alignment angles at optimal values under braking. Toe and camber can change causing loss of grip or stability, as well as have negative aerodynamic effects that are optimal at the prescribed ride height.
Edit:
The control arm design also allows in the QA1 OBS trucks the ability to run over 5 degrees positive caster increasing straight line stability, which also means even MORE camber gain in a turn.
Detroit Speed has complete hydroformed front subframes for Gen 1 & 2 Camaro/Firebirds that correct handling issues due to better anti-dive characteristics. That’s why you see so many Optima Street Car competition folks using those type cars and placing high in the rankings.
Here’s a quick and easy to understand video on what anti dive is.
Automotive Videos. Anti-dive suspensions are used to reduce body dive by altering the front suspension so that the forces resulting from braking pass through the control arms and suspension linkage rather than through the coilovers or struts. By reducing body dive, the front wheel geometry will...
