SORRY THIS IS IN WRONG SECTION. FOR SOME REASON I CANT POST IN TECHNICAL SECTION! Right im intrested in some tein springs. They guy whos selling them states they drop a glanza 35mm. Im sure they would work fine on my n/a unless glanza's are lower standard, because it says that are designed to work with OEM shock. 50mm or 57mm actual ride hieght drop is to low for standard shock. The problem is that ive seen some other tein springs which are the same but state that they drop yur car like 35mm. He hasnt stated whether they are tein S springs. Are there more than 1 tien spring type for the ep91?
