Any speed CD-RW discs (under 24x) will work just fine at their rated speed.
Unfortunately, I have found that CD-RW discs can't be burnt at a faster speed than they are rated. I have a pack of 16x TY CD-Rs by HP that burn just fine at 40x. I have the 52x Lite-on that you mention, and my Memorex 4x CD-RWs can only be burnt at 1x, 2x, or 4x speed. 🙁
