Just picked up a set of Koni yellows for my car. Trying to decide on springs. Which is better Eibach or Welmeister at 100lbs.. ? Is there a difference in size? Don't want too stiff of a ride, so figured the 100's would be best and I don't want to lower the car too much if at all. Running 195 65 15 tires. The other question I have is regarding the Konis. Can the factory round cad plate be used on the top of the koni strut where the nut secures it to the strut, or do you have to use the smaller koni one with the notch tab on it?

Thanks,

Tod
