Okay, after I put my Mugens on I would scrape my rear tires when I hit a bump because the wheels stick out more than my HX wheels did. I went out and bought some spring rubbers from Advance auto, and inserted them in the bottom of my coils. The car rides MUCH better (stiffer), and the tires don't rub anymore, but I noticed that the top of my springs, the coils are touching. Is coil bind going to be a problem with my springs? They're Neuspeed Race springs.

 

If you take turns spiritedly or go to the track, upgrade to better springs/coilovers. Otherwise, I wouldn't worry about it.
