I never removed my 4WS
Just compared the 4WS model with the regular SI on Edmunds.com
I have since reinstalled my power steering since 4WS without it is pretty pointless.
Pretty much removed all the brackets from front to back that are pointless.
Interior is stripped right now, but I ordered some Dynamat to place in the car before installing brand new black carpet and making the back a hatchback of sorts without the back seats being used.
I have my dash out of my car right now and am working on removing the entire SRS system. I removed the passenger side airbag unit and I can tell you that one piece weighs way more than I thought it would. 15-20 pounds at least, but I will weigh it soon with the rest of the brackets. The srs system has this weird heavy metal support behind the dash that weighs a good bit too.
I just simply dont trust a 17 year old airbag system, and in the second place I always wear my seatbelt and do the speed limit. Plus airbags can inflict more damage than good, and i have adjusted my seat belt to make sure it does not slip and let me hit the steering wheel or dash.
I love my 4WS and will not be taking it out, so you can all rest easy.
