A little help please,

I have been given a set of gmax 60mm g max shocks and spings front and rear, complete with shoxker tops/mounts for my mk4 escort cabriolet.

I have spoke to a lot of people and they have told me this is too low and will ruin the ride. What i want to know is will these struts be ok if i get a new set of springs? (35-40mm?) I may be being a bit dim here but any help would be helpful.

Thanks in advance.
