Not without a caster plate.

Because castor angles are fixed on a BMW MacPherson Strut? And the only way to adjust it is by adding castor plates?
Seriously? I had to answer that? It's like talking to my 4 year old daughter.

This is not a typical question that comes up everyday in forums, so I was curious to know if there was a back story to your question. I do not know if OP's desired to adjust the slip angle or address a self centering action problem (too little or too much) at low speeds. Adjustment to the caster is not typically done. By the way hack its not spelled "castor", it's caster.

Besides, the reason why (I think) you are getting attitude is because you were already given the answer: Quote:
P.S.: Do not attempt to insult The HACK. He is one of the few people out here from whom you can actually learn something worth remembering!

He asked the question to opens the forum, which allows us ask for follow up questions. I knew the answer, but I do see my error (I'm big enough to admit it) of not being clear to whom I should have addressed my question, which was not towards the Hack. I was not being insulting. The two words have the two completely different meanings. I do agree he's knowledgeable, but does not give anyone the right to give sassy comments without reply back. I think I've explained myself clearly.

Alternatively, one can modify the OEM plates for added caster the same way Dinan did for camber.

My E36 M3 also had macpherson strut, but bentley gives a range for front caster in the alignment section of the book. Why would they give a range if it is not adjustable?

The stock plates are fixed, youre right some macphersons (sw20 mr2) can be flipped around to "adjust" caster/camber. Ground control/Vorshlag offer plates with both caster/camber adjustments.

Those are the acceptable ranges. Once you are out of the range you should be looking at defective/bent components to replace to get you back within range.

Caster on the E9x and E8x chassis is VARIABLE during the turn, unlike most strut suspended cars. For most cars we ship Vorshlag camber plates in the full-additional-caster position because most chassis need more caster and the only way to get it is to change the static caster. But the E90/E80 have dynamic caster provided by the multi link lower arm. We ship camber plates for those chassis in the no-additional-caster position as we feel they already have enough due to the unique suspension.
