Hello everyone! I just joined the site yesterday, the same time that I bought my 2005 Wrx WR Blue. Its been a long time coming. So I guess that I have a few questions right off of the top. First of all, what kinds of mods can I do without voiding the factory warranty? I know that the factory warranty covers a lot of stuff so I need to make sure that before I install aftermarket equipment. Second question: what is the weight of the stock wheels and tires? Third: what is the largest wheel size that I can fit on my Rex? And lastly, this question is for the site administrators....is it possible to have a geographical map or listing of the members for ease of setting up meets, tech sessions, BBQ's, etc..? Thanks and I am super happy to be a member and a new owner of the WRX!
