im on neuspeed sports and tokico blues, their warrantee is void for anything over 1.5'' but I've been fine on mine and they ride ok considering i only paid $100 for them (1mo. used). my friend had his tokico blues on race springs and one of them blew and he just sent it back and they sent him a new one w/ o any questions. ive read many people on the boards have done this also...
