Think there are a few people in 172 style clio with either H&R or FK. In my opinion cant go wrong with either.
Didnt go H&R route on mine as only supply the fronts so think it would have been another brand for rear, and more expensive than FK. Told by Performance Driven in Taunton, where I got mine fitted, that get a lifetime warranty with FK as they were fitted by FK approved dealer.
Go with what you can get and what deal you can get. Performance Driven were offering free fitting when I bought mine, inc lowering torsion bar.
