I actually found a couple of these on ebay. These strut tower bars are from
http://www.cpracing.ca Their prices on their website are cheaper, and they include free shipping. Their rear strut tower bar is all welded, no joints that allow movement (this impressed me) AND to top it off it's a 4 point STB which means it mounts to the floor in the back and the front STB mounts to the firewall.
I was going to go with a set of Megan Racing strut tower bars, but these seem like they would provide better rigidity. Does anyone on here have 4 point strut tower bars, and if so did they really improve the chassis?
