I have thier pro version on my 92. I bought the car with them already on it. Wasnt happy with how stiff the ride was at first. But i raised the ride height a little and softened the ride progression knob a few clicks and I'm happy-go-lucky now. They have been on there for at least 5 years. No noises, even when hitting some large pot holes we have here. I like them, even if some here dont consider them to be a good brand.
