<br>O.K. this is what I believe to be true: <br>FRONT: non-sport- (22mm.) sport-(27mm.) both hollow<br>REAR: non-sport (12mm.) sport-(16mm) both solid<p>I have found some conflicting information by seaching the archives that suggests that the non-sport front bar is also 27mm. This could only make since if the sport bar were contructed with a heavier gage steel. Are there any other differences? I.E. bushings, end link hardware, ect....<p>I am looking to upgrade my 97 1.8TQM with 98 sport bars and springs paired with bilstien H/D struts. I am hoping to end up with improved handeling with minimal harsness and reduction in ride height. I have gone all out on my previous cars and regreted it. I am looking for a "middle of the road" and conservatvie suspension upgrade. Has anyone else done this or something similar? <p>I Would appreciate any comments, advice and or constructive criticism. <p>Scott

The older 96/97 front bars use to be 22mm....with 12mm rears...the<br>new 98 sport and non-sport "front" bar, I believe, is 27mm and hollow.<br>The rear bar is where you get the difference...it is 16mm. The Neuspeed<br>front sway bar is 27mm, but SOLID. The rear Neuspeed sway bar is<br>solid and 22mm. I have the part numbers for the sport suspension if<br>you want them...just email me.<p>Steve S.<br>97 2.8QM<br>H&R coilovers<br>Neuspeed Sway bars
