I'm lowered on coils.....the vibration really isn't that bad....but the fact that it does vibrate worries me.

Its hard to catch on video since you only feel it. On stock wheel and Road Magnet Springs I get a slight vibration when you are stopped while in gear but you really don't notice it if you have your radio on. Every once in a while i get a shake while accelerating around 20-30mph. but its nothing ridiculous. When I put my 20s on the shake kinda got worse when accelerating.

From what i have read it seems that it kind of varies and also depends on how that persons interpretation of "bad vibration".

Im lowered on H&R springs and it does vibrate. I did install new CV axles on the front yesterday and the vibration is significantly better. Even before it wasn't that bad, I don't regret it at all. Plus it doesn't vibrate all the time, it comes and goes. Don't go too low, thats all I can tell you.

I'm lowered on H&R springs and have almost no vibration. I have aftermarket 18's with OEM size tires. The only notice I can tell you is the ride is a little bit stiffer hitting bumps and uneven roads. Overall the stance and look is well worth it.

Thank you all for the replies, I'll probably lower it cause I cant stand the wheel gap.

the vibration comes because the front drive arms are at a weird angle after being lowered.
as far as how bad it vibrates??? i had mine lowered and running 20" staggered, and only felt a little vibration accelerating between 20-30 mph,

I'm dropped on BC coils and don't get much vibration at all. It's an occasional thing when starting at stop lights and only lasts till like 10mph. Most of the time it doesn't happen at all. Front fender to ground is about 24.5" i think. Rear is a bit lower than that probably about 24" fender to ground. Only issue it's caused is I'm going to have to replace my passenger axle soon because I can tell it's slowly starting to go. Think I hit a decent bump on a highway bridge or something and it strained the axle angle and the CV boot crapped out some grease. Nothing serious yet though because it didn't lose too much grease but I'll be replacing shortly and playing with setup as I'm going to 19" wheels in a few weeks.

I have very minimal vibration at idle, other than that no issues at all.
