I have a set of Wilwood Powerlite calipers that I'm putting on the rears of my1.6 turbo build car. I purchased the requisite hardware from Flyin' Miata so that I can use the calipers with 2001+ Sport rotors. Should I use dust shields on the rears? I am feeling a bit too lazy to pull the hubs again and replace the new dust shields with the larger sport package shields. Is there any real detriment to not having the shields in place?
