Installed Swift springs today. I read tons of reviews of people saying the ride was actually smoother than stock despite these springs having a higher spring rate. This is what drew me to them. I must say...I'm impressed!
I also tried to bolt on my z1 20mm spacers and quickly realized that none of my 21mm sockets would fit in the hole to tighten the 'inner lugs'. I even tried the lug wrench in the trunk and still didn't fit. Am I just incredibly stupid or is there a special socket you guys are using on these bolt on spacers? There is barely any space, I don't see how any socket would fit.
