I keep hearing that these aren’t as good as Ireland engineering’s kit. Also heard complaints here and there that ride height adjustability is on 2in.
2in is a lot, you can also alter height by changing spring size later. Its a tried and true piece of kit, and Jay at GC is very knowledgeable.
IE stuff is basically DIY coils, might as well just use ebay sleeves and whatever shocks you want at that point.
