Does changing PSN nick keep GT5P+5+6 intact..?

Miami, FL, CUBA
When I first got PS3 I was bit ashamed lolike look @ mistamontiel consolitis I just never had beefy PC hardware

But I've had it and been wanting to keep my nick across everything

Would this ruin my Gran Turismos PS3 data I assume? Don't care about the rest just my precious GTs

Merry Holidays!
