    Note: Not responsible for any damage to you or your car, this worked on my car so will work on yours. The kit as been tested over and over countless hours by Rick@DEFIV. If it doesnt fit you did something wrong.

    ***This tutorial assumes you know how to get your car secured on jack stands, if in doubt do NOT attempt this DIY!

    Suggestions:

    Do NOT use a torch to remove bushings, it is not needed and can deform subframe amd make install of bushing appear off...they are with in .001" tolerance. They fit PERFECTLY.

    Notes:

    *I assume you know how to take exhaust, panels ect off.
    **The design off this product is the copyrighted by Rick@DEFIV.
    ***You can use a hole saw to pull out bushings instead of pipe if needed.

    Here is the work of art, this kit really impressed me with how close everything fit....I can't imagine the testing involved to get this to spec. Rick Has some of the best customer service in this bussiness period!

    Ditto, nicely done! Might be a good idea every so often to make a good visual inspection for signs of metal fatigue or cracks - solid bushings remove flex for sure, and may also pass along stresses that the flexible bushings previously absorbed.

    very good point, haven't noticed any yet, this kit really does transform this car...wheel hip is gone...launches better since I put this on a few months back.
