all adjustable coilovers will be stiffer than conventional shocks no matter the brand.
People who use whatever brand tends to defend the one they got...
what I would recomend you is to go for those you'll get better support with. we have different traders offering different brands on the forum. check what sort of support and warranty they offer and make your own choice
If you still want to go for D2s, I would recomend you to make sure you buy latest street design that came a year ago (some shops might still have older design in stock...). I still haven't heard anyone complaining about those new model. and I know quite few guys using them on starbos... here is a pic. you'll notice new design bottom mount is black, while previous design was purple
those new design model use larger struts, have rubber top mount camberplate design and one year and a half waranty...
