Hi there, yes I swapped the 350's out to the rear when I put the 550's in the front. I did this swap after only doing 10 odd laps in the car, as it was scraping the LH side panel off on one of the long sweepers on my home track with the std springs.
The spring swap made a big difference to the feel of the car, much flatter cornering. I went up on front and rear shock settings as well which also helped. Around 1.5 secs were shaved off lap times but some of this was probably due to added familiarity with the car as well.
I expect that the car would have been quicker again on these springs had it been aligned and corner weighted. We ran it straight out of the container initially and found in the weekend that it lacked negative camber and the toe was not quite there either.
