Should be per pair

So the wheel spacers gave you more negative camber? Can you explain how spacers altered the alignment?

The farther the wheels move apart the angle between the wheel and the axle becomes larger. Thats what I believe causes alignment to change. Not sure what other factors though

I looked up more information and the example that made the most sense to me was imagine a spacer that were 20ft long the center of gravity of the car would obviously bring down the car lower causing more negative camber. A lot of other things associated with the suspension also change but that made the most sense. So the larger the spacer the more significant the change in camber would be. :tup:

Are H&R bolt-on spacers hubcentric? If so, I'll get them right away!

Any pics of spacers for the perfect stance with Swift Springs? 15/20 or 20/25?

Plenty of pictures on the forums, but for a few millimeters of poke, 20/25 is the way to go!

Do stud-replacement spacers require retorquing after driving or is it just for bolt-on spacers?

This is what I'm running. But it really seems like an extra 5mm up front is going to work. 25/25 anyone?

always retorque regardless of spacer type or no spacers at all

you want to retorque the lugs anyway a few times after driving 5miles or so after taking the wheels off the car.

for stud replacement type, you just retorque the lug nuts.

for bolt-on type, ive been using loctite blue on the inner nuts and let them dry overnight. no need for retorquing those, but i still retorque the wheel lugs that hold the wheel to the spacers.

I thought this was a descent video. Pretty basic, but well explained.

What kind of or brand of spacers did you use? I have a 2014 370Z with the stock 19's and would like to put 20mm bolt on style all around spacers. I was told by Stillen that the H&R's 20mm bolt on would not work on the front, that is the reason I ask.

I did H&R 25 mm in rear with stock 19" sport rays & 275s

So can you use 20mm bolt on style all around?
