I am curious as to what the mini GP would be using for suspension.. although a lot of similar parts, I would think it sits lower than the m35i. At least what I would say is that our struts would be good for lowering springs, as they are adapted for being lower than stock already. I am not holding my breath for a lot of aftermarket parts on the m35i as it's such a low production and not sought after car. That may be the only regret on my part... I love modifying my stuff, but availability is certainly very very low on this.
While I'm here at work I went to realoem and tried to look up the parts.. it seems the spring itself isn't even listed as available as it's greyed out:
