I just got home and need to get the alignment done, but would that explain the car being a scary mess on the freeway?

We installed the springs and SPC stuff today and I had to make a 40-mile drive home. Maybe the rear springs weren't settled enough, but at one point the car hit a bump and I ended up half in the next lane.

It's kinda skittery over bumps. No freeway safe, for sure!

 

You need an alignment... tires won't last long under those conditions..

 

That does not sound like just alignment issue. If your camber or toe is even moderately off, it's not going to cause frightening bump steer. I say moderately because GF210s are not extreme lowering springs so OP should not be out of spec by much. My guess would be that if the dampener is tired, it'll allow the spring to recoil with more force than it should thus producing this type of behavior. What's the dampener and how old is it?

 

what SPC parts did you install? new arms and or toe bolts could put you far from spec

 

^ +1, same thing i was thinking.

Springs have nothing to do with it, except maybe a little more camber/toe, its the arms/bolts that will put you far out of spec.

If installing arms, you should get an inital alignment right afterwards imho, pref before driving. Then get another once the springs settle.

 

springs affect both camber and toe, since you cannot change one without changing the other

 

Yeah it has the spc camber arm on the rear. It's just a little wild back there at highway speed. Car actually was riding great at less speed. I'm hoping it's just the toe bolts and arm needing the alignment.

 

^ Thats what i said...?


The point was that installed/undialed arms/bolts would be more of a reason why he might be way out of spec... he wont get too much - camber ( and therefore toe also) from GF210's.

 

You definately threw the specs out of whack, when i installed my camber arms and my trip to the alignment shop was scary, any bump the tail of the car would wiggle...at the shop my toe was 42 degrees one the left and 1.03 degree on the right.

I actually didn't install the toe bolt, i tried to, couldn't fit the dremel in there so gave up.

With Tokico Springs and Ichiba Camber arms, i was able to achieve 10 degree toe with 1.8 degree of camber...the rear still wiggles slightly on bumps though...

 

Thanks. That's exactly what I felt. Scared the s&@t out of me for a bit.

 

We got it dremeled alright (that's a weird back hole to get) and the SPC toe bolt in there but obviously had no idea how much to tighten it. I'm hoping that's the issue.

 

The recommended setting by NISSAN is .08 degrees, i got .10 and I am still getting a slit "wiggle" when i go over bumps...its Toe this sensitive?

 

OP, come back and post your alignment specs before and after and let us know if alignment was indeed the issue.

 

Will do, Ziggy, although I don't want to come across as the "enthusiast who reads the internet too much" guy at the shop, haha

 

That's OK. You secret will be safe with us. We won't tell

 

I'll see if I can scan in the settings sheet they gave me, but long story short, one of the rear camber arms had the bolts a little loose and the camber/toe was WAYYY off. Like two or three degrees.

Runs perfect now!

 

Here's the alignment sheet. Obviously, no front camber arms, so that's out of spec.



I'm definitely curious if the SPC rear toe bolts come loose easily. Just in daily driving, we'll see.

 

a moderator in this forum had reported that they do come out of spec over time....the only way to fix this is to lock them im with square washers and get true coils with toe arms...

 

my car did the same thing after lowering it on sportlines (similar drop) and the spc rear camber kit. turns out when i went in for an alignment my toe was waay off in the rear and my rear sway bar was loose. Tightened the brackets on the rear sway bar and did the alignment and the car was perfect once again.

 

Over time, yes. You need lockout washers broheem.
