I actually purchased the racks from Nissan (in Mississauga), it was far cheaper than any rack store. The cross bars & feet are Thule brand. The actual bike mount is from Rack Attack (Canadian website) and you could order it in any colour you want (I picked red to match the car). It works well, fork is secure, and I bought the locks for the fork mount. I do secure the bike when going on long trips with extra ties to the mount, but for short trips to daily biking sites, I just use the lock & tie that came with it.
I even take my bike mounted on the car & will leave it on my car for the day while at work. When I do that, I use an extra lock that I wrap around the cross bars / bike mount.
Close up (notice the extra ties used - road trip to Quebec):
EDIT: The fairing did not come w/ the racks, my bro stopped using his roof racks for his SE-R, so he gave the fairing to me. It reduces ALOT of wind noise when the bike is mounted. Without the fairing, with bike mounted, I could not open the sunroof.
