If I had an eclipse, I honestly would go with a neuspeed front STB and a sprint Front STB. The neuspeed bar is kinda small, and does not stretch across teh main stress points of the strut tower. it does help out a little 'though. I know Neuspeed doesn't make a rear lower bar. they trashed the idea early this year becasue they thought there was no market for it. Matrix, and Pilot Motorsports both make rear lower tie bars for eclipse. I have the pilot bar on my car. it doesn't have hime joints like dc sports bars, so it squeeks :( it does the job 'though.

Have fun!
