I run hc+ all round. Only the rear ones makes the noise(not enough load to heat up properly?), I know because I had the front one first. I have leant my leason, so I recommend b spec rear.
If u can afford more expensive coilover, why not
I would love a set of ohlins myself. On the other hand(dont want to troll), kw v3 runs 7kgmm spring front 5 rear and its progressive spring(act as softer spring first). std is 8kgmm all round, so it will be harder. Valve quility does contribute to coilover harshness, but mao can order softer spring combo for ya. At last Std is almost a third of the price of kw too, customer support is great from my experience.
As soksta mensioned any coilovers are harder than spring/strut combo.
