i had bilstein gas shocks on my previous car, Ford Escort, brand new and they made a difference, ai have no idea what could go wrong or what bad review there could be - bilstein is number one shocks brand I think, or at least in the first league
you cannot go wrong only the ride maybe a bit firmer than the stock shocks
you can also try a sport version or race version the letter one is of course the firmest and most expensive
i really like the pssst sound of the gas shocks BIlstein , i am going to get them for my panda when these stock wear out
