I have read everyone uses the purple spring and shimming after doing tires. I just ordered some og bighorns 27x9x12 front and 27x12x12 for the rear. Is anyone using or has tried the gold or white spring as opposed to sticking with the purple? If you have what’s the overall difference after you installed them?
