Got a 97 Volvo 850 T-5 Wagon

want to juice it or bag it, what's the biggest size wheel i can fit on it, and still retain a/c. remember it's gonna be layed out. I dont know much about this wagon. any help would be appreciated.

GOOD LUCK!!!
If you want to see what mine looked like check out my V70 T5. It is on 18"s with 35 series tires. Not the best clarity but it's all i had @ the time. It was a few years ago. If you want to lay it out to the body you will need to unibody drop it. If i remember right, mine was about 3/4" off the ground underneath the car. It was bottomed out on the fenders in front & the rear was bottomed out as far as it could go without MAJOR modification. As far as the A/C thing goes it's not really like a truck so keeping the A/C shouldn't be a problem.
