The way it sound the rattles have been fixed... So if your in the market for Coils on a bugdet... BCs or Megans is the way to go... if you have bank... go with KWs Or JIC or maybe HKS...

 

are they really big different between the (BC/Megans) and (JIC/KW) ??? im looking for a sporty feel, i like harder suspension...

 

They all have basic functions, dampening adjustments and ride height adjustments.

The cheaper coils are known not to last as long, i had a customer with a G37switch his low end coilovers after 6 months because of the rattle and the rear shock was blown already. 8K miles on the those coils.

As for the quality coils like the JIC/KW'S aside from better and higher end construction, you can have them re valve here in the US if ever warranty issues come up or you need them to specifically tune your suspension to your needs, ie track set up. They are also safer because i've seen the cheaper coils snap in half.

Hope that helps
