WRX receiver hitch

["GARY FELLERS" <Gary_Fellers@worldnet.att.net>]

I would like to install a receiver hitch (1 1/4") on my Subaru WRX.  I have
two questions.

- Can anyone suggest a good place to get a hitch, preferably one that I can
simply bolt on?

- Since I run in DS, would the addition of a hitch affect the class?   In
other words, would the hitch be viewed as modifying the frame stiffness?

Thanks for your help.
