I recently purchased my 87 that is running 215/70/14 all around. I plan to change the rear spring back to new stock ones I ordered today. The car sits high in the rear cause the previous owner put a set in from a Caprice Wagon. I'm gonna put on my 15" 84 Hurst wheels on it. Thinking about running 235/60's all around so I can rotate all 4. What do you think?
