The attached images seem to show how the sensor is checked for proper function.

Since the pictures posted seem to show no ability to adjust them on the actual sensor to compensate for "normal" ride height ... I speculate that the only other places to adjust would be either at the headlights themselves or in the software that reads to voltage output from the sensors.

Adjusting them at the headlights basically moves the elevation to one extreme or another which kind of defeats the purpose of the sensor, so I am still banking that the system can be re-zeroed somehow using TechStream similar to how Infiniti's are re-zeroed using CONSULT.

Anybody here have access to a Factory Service Manual?

 

Thanks, I have the super down springs.. the headlights are only pointing down very slightly for me but other than that the visibility is still pretty good. Ride quality wise it is a bit more bumpy than stock over bumps and dips but I didn't notice the side to side rocking that ChuH described on normal setting. On sport+ it is definitely very firm but still not as harsh as the '09 IS 350 with sport suspension that I had.

some more pics...

 

So what happened to OP's car? Khalendar, did you install it yourself? OP might also have a dead shock for it to wallow like he described.

 

Nicely done! What lip is that?

 

I took it to a shop to get it installed

it's the TRD front lip

 

Where did you get them from and how much were they?

 

Where have these pics been all my life? I have LP, and I've been waiting to see a lowered LP with the aftermarket F Sport wheels. Me like! I may go with that set up eventually.

 

if you dont mind how much did you pay for that lip and where did you get it from? thanks!!!

 

i got the unpainted one from nigel-jdmparts - ~$850

 

Install the new wheels and tires yesterday. Springs settled after more than 2 weeks. Alignment done this morning and following are the results.

Front Caster:
Driver: 8.2 deg. [within spec] Passenger: 8.4 deg. [within spec]

Front Camber:
Driver: -1.5 deg. [out of spec] Passenger: -0.9 deg. [within spec]

Front Toe:
Driver: 0.05 deg. [within spec] Passenger: 0.05 deg. [within spec]

Rear Toe:
Driver: 0.15 deg [within spec] Passenger: 0.15 deg. [within spec]

Total Toe: 0.10 deg. [within spec]
Thrust Angle: 0.0 deg. [within spec]

Rear Camber:
Driver: -2.6 deg. [out of spec] Passenger: -2.3 deg. [out of spec]

 

Why is the front camber so weird? one side within and the other out of spec?

 

Not sure I would assume to compensate the curvature of the road. Didn't get the chance to talk to the tech that did the alignment.

 

IMO he should have adjusted them to the same values so left side and right side match. Caster is different and camber is different and that doesn't make sense to me.

 

Should of gotten a measure of suspensions before the drop spring installation. I think I should of gotten Down Springs rather than Super Down Springs (too aggressive). Hope someone has a alignment printout after their spring install.

Khalendar, do you have the alignment printout on your install?

 

Um where's the pics
