i am looking in orderng a set of strut tower bars for the front, rear and lower. i have a spyder and was wondering if they are the same or if i need a diff one if i can do one at all. any one installed before on a spyder.

I don't think any rear upper strut bar will work with a Spyder if you want to be able to put the top down. I recommend upgrading the sway bars first. Makes a huge difference.

Ok that makes sense, thank you for the advise

Upper rear strut bars are not needed in spyders. We have that bracing in between the strut towers, since we don't have a solid top.
