I have H&R's and Boge turbo gas on my '86 4kq. The car now handles very well, but the turbo gas inserts give a very hard ride, especially on the bad streets of Pittsburgh. I would recommend the Boge pro gas inserts. They are supposed to handle well, but they won't take the cracks and pot holes in the road so hard. Just a thought. Tom B. '86 4kq
