Hey guys,<P>Well, I think my suspension is slowly dying. The car is not riding as smooth as it once was. Anyways, I'm looking into suspension upgrades.. Here are some quotes I got:<P>Koni sports are $501.20<BR>Bilstein touring class $319.00<BR>Bilstein heavy duty $399.00<BR>Sachs/Boge $334.00<BR>(excludes OE self leveling rear)<BR>sets of 4<BR>Eibach Pro-kit $249.00 (These are due 5/1/02)<BR>B&G springs $219.00 lowers 1.6"<BR>H+R $269.00 Lowers 1.3" <P>Can someone please explain to me the difference between the Bilstein heavy duty and touring class? Also, can someone justify the price for the Konis? Are they worth it? What about springs? I'm leaning towards IPD right now (due to the summer sale) but I had H&Rs on my old Maxima and loved them. What about B&G (although I'm a little reserved about the very low ride height). What about the other ones? Any input is much appreciated.<BR>Kai, I know you have H&Rs and Bilsteins. How much did they lower your car and what type shocks did you use? Thanks.<P>Regards,<BR>Mike
