nah i havent had any problems with it cracking the window.. ive had my 15s for almost 2yrs and no problems.. i jus need to secure them so they dont slide around my trunk lols
you can ask wildman or the admin they'll give it to u dude lol
i forgot how i got the password i believed i jus asked for it
i remember sumthin about havin a certain number of post tho
but check up on that
they dropped way lower than my h&r's and eibachs that i had, they pretty much had the tires tucking, they are pretty cheap if your looking for something that's in the price range.
