I agree with Littlebeast.
That Proton was running 35" tires... I can't remember his name but I'm pretty sure it was a 3" body lift as I helped him along the process.
I installed a 3" body lift to help run 35" tires and reduce strain on the drive-train. If you're going less than 35" tires, I wouldn't recommend it because there's a good amount of changes that need to be done for the body lift to work. If your ARE going 35" tires, then there are pros and cons to installing a body lift, one of the pros is a smaller cost.
Here's more information on the body lift install.
