In Need For Speed: World, is there any gameplay difference between the Lustra, React and Glint packages?

NFS:W, after you painstakingly reach level 5, offers you a whooping choice of three performance upgrade packs: Lustra, React and Glint.

As much as I'd rather get a new ride -- something that was far easier in NFS:MW -- I'll have to consider getting a package instead (mainly for pursuit purposes).

Which one exactly? Is there any gameplay difference at all? They all cost the same and all upgrade car stats by the same -- this fake choice kind of puzzles me.

ZoogieZork's comment and the offical blog post seem to imply that no, there is no gameplay difference indeed. Not yet, anyway.
