Congrats on the new Ohlins R&T suspension. If you are using Vorshlag camber plates - What spring rates did you end up going with?
As for camber, yes, there's a chance the toe will change significantly if you make a large change in camber. While you were on the alignment rack you should have had the shop change your camber from your street setting to the track setting and then tell you how many turns of the tie rod it takes to get the toe to change from its street to track setting - some people mark the tie rod, others remember the number of turns for a given change in camber.
If you are running street tires on the track then you might be able to get away with a compromised steet-track camber-toe setting, however, if you are swapping to r-comp, etc tires on the track then you'll definitely need to run more camber.
