The height difference on the latest cars from the first Focus RS is 11mm – We have measured this.
Our kit is still compatible with the later cars also.
In regards to warranty, we have multiple Ford Dealers in the UK and EU purchasing our kits directly from us and installing into customer cars so rest assured there’s nothing to worry about.
Kits are in stock and ready to ship.
