sin^-1 (delta the distances top of wheel to bottom of wheel)/(diameter of wheel. Not advertised wheel diameter, but the actual wheel lip diameter. Usualy advertised in inches plus one inch (guesstimate). same units, otherwise you cannot divide the two, duh

Side A; 18mm delta, 18 wheel lip diameter
sin^-1 (0.7087/18) = 2.26 degrees or -2.3 degrees of camber

Side B; 28mm delta, 18 wheel lip diameter
sin^-1 (1.104/18) = 3.51 degrees or -3.5 degrees of camber

Geez Sid, did you not pay attention when you were installing the links? One side is close to stock, but the other is turned out 1.5 turns!

With the H-Sport (Promini, same thing), usually 1 full turn = 1 degree. With big rear swaybar, you want about -1.5 degrees

Basically, you want about 0.5" or 12mm delta from top of rim to bottom of rim to get -1.5 degrees of camber.

You're welcome,
Ryan

Got it. Went out and got a 1-1/8" wrench and ended up with a 15mm delta for both wheels at the top. What do you calculate the camber to be? You mentioned 12mm for -1.5 so I should be pretty close?

Thanks and leave the drawing to me

15mm delta equates to -1.9 degrees of camber. That'll work

Motor-On!
