These are good coilovers if you’re not willing to wait for better brands like BC. I’ve had em for only a month and time will only tell how long these will last, but I’ve drove them well over 2k miles already considering that this is my daily, and living in Hawaii roads here are pretty harsh… With the stock springs ride quality is ok even when setting dampening to soft max, not great if you’re looking for a comfort ride. However I changed out the spring with swift 5” 32k front and 6” 28k rear. I only got this brand coils just to go low as much as possible and not so much for track or ride ride quality. Build quality is good for its price and had no issues with fitment at all, just make sure you use the sleeve adapter for the struts as for GTI its 54mm.
I’ll say if you have the money and patience go for BC, if not these are pretty good despite the negative feedback it gets from others. I actually have 2 guys running this brand too well over a year and they never had issues with it.
Fits GTIs with DCC dampening as well just make sure to get cancelers, and sway bars end links too.
