So I’m currently in an adventure of restoring a car I’ve owned since 2015 and which has almost 260.000km - it’s a Volvo T4 from 2000, 200hp from factory, wishing to tune it up to around 400hp which is pretty doable in those first generation engines.
Suspension is one of the things I want to change first and I’ve seen some KW coilovers that everyone praises how they change the behaviour of the car for good. However, after talking the workshop where I always bring my cars to he told me that I would be better avoiding coilovers, they tend to be problematic in the long-run and unless you’ve got a real sportscar is not really necessary.
Which are your thoughts on coilovers? Which is their extra maintenance and why would they be problematic in the long run?
