I've had them install my lift on a KDSS 4runner. Everything went fine, well priced, and they did it quite quickly. Small issue, the back springs aren't completely seated, doesn't seem to matter. No KDSS lean, although I had offsets for the passenger side.
Dmitry has a lot of experience with 4runners. Stellar built was recommended to me by Trail4R.com guy (Brenden), who is local too.
Stellar built is quite big with the subaru community and praise his work. I knew about them prior to getting my T4R, but I haven't had any first hand experience with his work. That said, the people I know who have gone to him say his work is great. And I've seen some of his bumpers he's built on some subaru's. Job looks good.
