You don't need longer wheel studs to mount wheel spacers. They just bolt onto your factory studs. Just make sure to use lock tight. I had one of mine come off while going 50. I noticed the biggest difference when I changed to a dual diaphragm booster. But it was the last peice off the brake upgrade that I did.
- FJ60 rotors
- V6 calipers
- FJ80 Master cylinder
- FJ 80 dual diaphragm booster
In that order. I daily drove it for at least a month between each upgrade.
