So i went to a tyre specialist the other day to fill up on nitrogen when i saw a eibach lowering kit. They qouted R3700 for the installation as well as balancing of all the tyres, etc. Is this a good price? Are there better kits available like H&R? Looks and styling is not my main priority now. Im actualy looking more at performance. Would this be a good mod or would the ride become too stiff and uncomfortable?
