hello.put a idler arm repair kit on my 91 300sel.i also replaced steering stabilizer,it was shot.the old benz runs straight as a arrow now.also put on 225/60/15vr yoko tires i had in my garage for my bmw.the handling has improved a lot.the vr speed rated tires made a big difference.the car handles a lot better,more responce.they fill the wheel wells nicely to.now i am going to put on new shocks,and move to rear of car and check out rear suspension.i have had this car 3 months and it is working out pretty well.this is the biggest car i have ever had,my wife doesn't like to drive it she says it's to big.
