Thread is full of wins. Instead of cement bags, i'd say just ride your car on shocks and no springs or better yet get them mad jdm coilovers from eBay, their the best out there.
ok...so i dont get the cement thing.. if your putting it in your trunk now only your rear will sag.... where would you put it in the front..stack it on the front seat and put a hat on it with a Halloween mask <-- you can use the HOV lane then....
Or are you talking about pulling out the carpet and lineing the floor board with wet cement and letting it dry... make sure you put your hand prints in the floor...
I don't understand how somebody can even attempt to associate the ideas of "hella-flush" and ghetto rigging his car by adding weight by using cement... wtf.
