Hi
To start, that’s an unbelievable price and would not even consider it.
I have the bilstein B14 coil overs and find them extremely good for not only handling but the car isn’t uncomfortable (it is firm don’t get me wrong) but I use the car everyday and it’s no worse than other sporty cars of similar level.
However even with the coil overs at maximum height, the car will still be 25mm lower.
If that isn’t the route you want to go, replacing for aftermarket shocks/springs would be a much better and cheaper alternative although I believe the tributo Ferrari came with Koni shocks as standard?
If your handy with tools the suspension on these are a very easy DIY, I would be more than happy to explain the steps to take if needs be and there is not a How to on the forum.
if sourcing aftermarket and paying a garage, It shouldn’t take them any longer than 1.5 hours in my opinion.
Regards
