I was toying with doing the Bilsteins instead but I love the way my Runner handles with the stock suspension. Then Brock gave me a great deal on his spacers and I couldn't pass it up.
I did not do the install myself, I used Brian at BDR Automotive in Holliston, Ma. I paid about double what you were quoted for labor, but then again I've known him for a long time, and he does real quality work. He previously was working at a high end Rover aftermaket 4wd drive shop and he owned a lifted 3rd generation 4runner so he is familiar with our vehicle. Since he has set-up his own shop about a year ago I wanted to throw him the business.
He also just installed CBeit's overland warehouse suspension, tires, etc and I hear that came out wonderful as well.
He did tell me that the install did take more time than he thought it would due to the KDSS so if you have that you might be in for an extra hour or two of labor??? He performed my alignment too, so when I picked it up yesterday it was all done. With the spacers, it drives just like stock..with the exception of the E rated tires (LOL). Just sits a little higher, and def looks real good to my eye.
