You will want to hang around.
There is only one aftermarket rear swap bar, that I will be offering a small group buy for.
So keep checking daily here.
There are not such thing as aftermarket control arms for this chassis, there never was.
There is one person manufacturing strut bars still and her name is Karolina Gocal on fb.
Also Jon Blakeman who is a member here is a dealer for SuperPro bushings and helped to develop the kit.
So you can reach them both on fb.
Also we have a suspension thread in our FAQ's so peruse that for a while.
Other than that, there is not much anything else and no nothing bolts up to our chassis that is not made for it.
And since we are already the best chassis out there for handling other than some Ksports which I am the author and still current dealer for, all that is needed to improve your suspensiong is replace ball joints, bushings and endlinks.
