planning on lowering the ride down 1.5 inches, will +/- 2 degree camber bolts be enough to fix the camber in the rear with that drop? will be getting ISR front upper control arms for the front camber adjustment.

 

Camber bolts add an additional +/- 1% more than the stock adjustment.

 

In the back camber is controlled by an arm not a bolt. The toe is controlled by a bolt and toe bolts are a very common mod to give greater adjustability. Aftermarket camber arms are also popular mods, just stay away from anything made by Ichiba. Their parts are junk, plenty of fail threads/posts about that company can be found on Driver.

 

i was looking at the Z1 rear arms, theyre on backorder for a month though and ISR front upper arms if camber bolts alone wont get me into spec

 

 

The front eccentric bolt & washer absolutely adjusts camber. The rear ones (all in the rear subframe set up) adjust toe.

 

actually the same way u elongate the holes for the toe bolts, the same can be done with the bolts connected to the stock camber arms. you can do it that way and install camber bolts instead of buying camber arms but you wont get a lot camber adjustment.

 

Thank you. You don't HAVE to camber arms when cars get lowered a bit.
The SPC eccentric cam bolt can be used for the rear toe AND camber slots. The eccentric bolt can bring you back to around -2.2 degrees of camber in the rear in my own experience and remember to zero your toe so you dont chew through tires. My continental DW's went for 23,xxx miles with 3 track days @ -2.2 degrees camber and 0 toe in the rear.

 

Makes me kinda mad I spent all that money on the camber arms now... of course I learned this after.

 

I don't know a heap about toe so sorry if this is a dumb question but, how low can I go before needing camber arms in the rear?

I plan to go pretty low with my car and don't want some crazy camber on it.

 

The general thought on here is drops of 1 inch or more need toe and camber adjustable parts. Less than that will not. So if your definition of pretty low is more than an inch plan on more parts to buy. But remember that toe is the tire killer, you can be a little outside the parameters of camber for the car but if your toe's tight you should see minimal wear from the camber.

Camber is how straight up and down the tire is. More negative camber results in the top of the tire sinking into the wheel well and more positive camber brings the top of the tire back out to the fender. / \ = negative camber \ / = positive camber. Moving the camber adjustment more negative will help the car handle better up to a point which is why Infiniti and other manufacturers will have some negative camber in their stock alignment set up. But more camber will wear tires faster.

Toe is how straight ahead the tire sits. You do not adjust toe with camber arms, they have their separate adjustable components in the rear of our cars. HTH

 

Helps a lot, thanks for this reply Blue Dream. I was planning around a 1.5 inch drop to begin.
