which set up would be the best performance wise? they seem very similar to me but i was wondering which would be the better of the 2 for occasional autocross? not too concerned about ride quality, just fixing the body roll of the stock springs & such.

Both are about the same.....I have used them both but on my car I went with the Tanabe only because there early support for the Versa. As somebody that AutoX his Versa all the time all you need is a strut bar save your money on any other mods and get a good set of Shocks but even that can wait till you get a little more millage on the car. Even my crew from my Race Car team (Nissan 240SX) can't believe how well the car handles with minimum modifications and one driver was on the Nissan Champion GTP design Teams of the late 80's early 90's and works on the present day Nissan off road teams in Chassis and Motor engineering an extremely stiff chassis. Check out the pictures on my website and you will see it in corners etc no roll very little lean really amazing with just Strut Bar/Tanabe's/Adj. Shocks. :wink5:

Hope this helps you out.
