Hi, I'm new to Runners too. I live in Uzbekistan and I'm sorry I can't help you with where to get best deals on parts.
I have a '90 4Runner, just got it about a month ago. I'd also like a lift and am thinking about ordering the body lift kit. I can't lift it too much since my wife then would have even more problems getting in to the car to sit next to me, she is a petite woman... So, I was thinking a minimum lift to put 31' tyres, 33 would be great, but not sure how it would look with a little lift. I currently have tiny 29' tyres which previous owner installed.
And yeah, tires are so expensive here, I don't know how I will afford that.
Sorry, didn't answer your questions, but hey, at least someone replied to you...
Good luck with your project!
