Has anyone switched there bushing using the poly bushing from GS? If so how did it change your handling? I'm looking to tighten up or make my steering stiffer. I drive so what fast and after 80mph it feels like my steering is too loose or soft. So far I have changed my suspension to Eibach Springs, Bilstein Sport Shocks, and I'm running 205-50-16 Viking Saab Wheels. I have a 330 xi BMW and I just like that stiffer drive feel. I know there are totally different vehicles but if I can improve on my 1999 93 why not. Also, the hatch brace that GS has looks nice but I was wondering how doew it install. Whre do you attach the brace to under the rear speaker area? Is there a hole there or must I drill one. I believe I have to drill one behind the rear seat in the center but the other two have me puzzled. Oh, I also installed the 22mm rear sway bar and that did improve the my ride.
