I have Rsx type s and base progess springs for sale. They have been in my car for about 3000kms. I decided to buy ground controls becuase I got a really good price. They are suppose to be a 1.4 and 1.0 drop I believe but they ended up at about 1.7 and 1.4. They ride awesome and handle great. I bought them for 265 im selling for 165obo. Cheers
