I was under the impression the prokit springs were a 15mm drop for a type R and the sportline was the 30mm drop. However most vendors including tegiwa http://www.tegiwaimports.com/eibach-pro-kit-lowering-springs-honda-civic-type-r-ep3-01-06.html and the main ebay sellers etc put the prokit at 30mm. Are there two types of prokit spring? As 15mm is all I need. Thanks
