I need to replace the springs on my 05 WR450 to match my weight of about 215 for primarily desert riding. I used the Race Tech website spring calculator to come up with the following: The stock front springs are .47, Race Tech recommends .469 so shouldn't need to replace them? The stock rear springs is 5.0, Race Tech recommends 5.44 so replace with 5.6? Do all of these figures sound correct? If so, I should only need to replace the rear spring with a 5.6? Thank you.
