I just put Bilstein's and new tires all the way around on my 1983 300SD. My rational was that I could expect to ride on the new shocks for 10-15 years or maybe more. Do the arithmatic to determine the life cycle cost. It also does not make sense to put your ride, performance, and tires at risk. Think long term $$$ and short term enjoyment.
