You asked about coilovers, and people are stirring you away, that isnt what you asked for.
Generally if your a younger guy, you can handle them, otherwise older crowd says they are too stiff for them. lol
Get coilovers dude, those guys never tried them , just the typical thought that they are track only. Millions of people rock coilovers on street just fine. Coilovers and spring/shocks difference is like night and day. When it comes to coilover talk, you will get opinions from people who never tried them or have no experience with them. You get plenty of adjustments with coilovers, and basically new pillow ball mounts with front camber plate.
megan racing is decent on a budget. They been out for a few years now and still around. Got them on my car and great for daily driving. ALot of 240sx guys rock them too. Tho these are not my preferred brand if I was on the market for some (they came on my car).
Im not a fan of ksport coilovers, Had a buddy blow 1 of them out on his lexus LS400, but they where cool to send him a replacement shock for it.
Can't go wrong with Tein, I had used Tein coilovers , steering arm, tie rods, tension rods in my old 240sx. Great japanese quality products and you can always have them service the coilovers, they can rebuild them for you at a charge.
Stance is another popular brand with guys on here, hear nothing but good stuff about them http://stance-usa.com/sus/products
I am personally wanting to switch my megans for a new set of Powered By Max coilovers, they are pretty stiff for some people though
These also adjust front caster btw
