So this might be a dumb question, but I need the answer. I bought some Race Tech springs. They are longer then the stock springs. I double checked the part number and it appears to be correct. Do I use the stock spacer or cut the spacer that came with the new springs shorter? Is the longer spring for the increased spring rate? Do I need the total length of the stock spring and spacer to equal the length of the Race Tech spring and spacer? Any advise would be greatly appreciated.
