Suspension drop and camber increase for track days

I have M3 LCA and TCK front camber plates/coil-overs. At present ride height, I can't get more than -2.75 front camber for track days. How much suspension drop would increase front neg camber to at least -3.0? FWIW, I get alignments after suspension changes.

Probably need close to 1/2" drop

I have only TCK camber plates. My camber in the front is -3.5. You need to drop quite a bit Iím assuming, I have no wheel gap in the front. From the ground to the lowest point of my front bumper is around 4.0 inches.

I'm on BMW yellow performance springs so is minimal drop and can get -4.0 with Ground Control camber plates in combination with m3 arms.

Changed caster slightly to center strut/shock adjuster in shock tower opening. Plenty of camber adjustment now.

With the ground control camber plate i tough -4.0

That's the best camber set up for HDPE... But on the street it's not really good...

Since the caster adjustment, my minimium camber is -2.2. Will probably remove my M3 LCA just to have street-friendly camber during summer travel months.

-2.2* shouldn't be horrible on the streets. Keep in mind the M3 control arms also help you lose the fluid-filled bushing.
