Didn't quite get to the thorough detailing that I planned so these shots will have to do. . Currently, coilovers are set up for an aggressive rake look. Driveability pretty poor. I'll be adjusting the fronts up a tad, and the rears down a tad. I'll try to get a proper shoot soon. Enjoy!

Looking very nice
Those are some tasty wheels and the emblemless grill looks great! Agree about getting the back down a little, I'm adjusted to zero gap F&R (26.25" to the fenders) and like the balance and not having the front tires under the fenders anymore. Makes the drive better and evens up the look IMO.
Keep those pics coming!

Thanks for the tip, blnewt! I've adjusted the fronts to 26.25, and the rears to 26.5. We'll see where it lands after settling. For whatever reason, each corner always settles at a different rate. Last adjustment, I fine tuned each corner height to exact measurements using a digital caliper and somehow still settled to different heights. Took before/after measurements of distance between locking rings, preload height-spring perch to top of strut.

I noticed you have SPC F&R kit. Do you think that's overkill to get your alignment to spec to do you think an SPC rear toe-bolt will suffice? Alignment is next for me.

I'd shoot for camber at least -2 degrees and your toe in spec (so your camber will be out of spec but close enough to keep your tires wearing pretty well). If your camber's over -2 you'll have noticeably increased inner tread wear. If your toe is even a little out of spec your tires will really wear quick. I'd get the alignment, see how close they can get it & go from there. At 26.5" in back they may be able to get the toe in and your camber will probably be out by.5degrees (so should be about -2) Your front that low might be slightly over -2. If you have plans to go lower I'd definitely get the full kits.

Thanks again! Before the new wheels and add'l drop, front was -1.6*, and toe in spec, rears -1.5, toe in spec, at about 0.75-1.0" drop. I'm hoping they can get toe within spec with the current height.

Does it matter if the camber angle is 0.5 degrees off comparing left to right, if the toe is within spec on each side? This was my last reading on 0.75-1.0" drop:

Front Left:
Camber: -1.6* (out of spec)
Toe: 0.03* (in spec)

Front Right:
Camber: -1.3* (out of spec)
Toe: 0.05* (in spec)

Front Cross Camber in Spec
Front Total toe in Spec

Rear Left:
Camber: -1.5* (out of spec)
Toe: 0.09* (in spec)

Rear Right:
Camber: -1.1* (in spec)
Toe: 0.11* (in spec)

After a bunch of aftermarket parts installed, time to troubleshoot some issues that has reared its ugly head!

Steering/car vibrations at highway speeds, 60+mph

Eliminated possible cause:
-Wheel/tire balance - had it balanced/checked twice

Possible cause:
-Alignment, toe out of spec - have not done alignment after add'l drop

-Need to install hub centric rings - I assumed the wheels were drilled for the 66.1 center bore, but will take measurements soon

-Project Kics Revo R40 lug nuts - low possibility but it has dynamic lug seats to prevent scratching the wheels, wonder if it requires higher torque tightening than stock spec

Anything else you guys can think of?

I'm guessing toe is the culprit and might have one wheel set up quite a bit different than the other. Interested in hearing what your alignment turns up.

Be sure to recheck wheel torque, too many shops use air hammers and could over-torque or uneven torque on your wheels, could cause the high speed vibrations.

I doubt the lug nut torque specs would be different w/ those Revo nuts 80-85 ft. lbs should suffice.

Quite a few wheel blanks come w/ bores bigger than 66.1 so hub adapters are all you can do in that case, hopefully yours are bored to oem infiniti specs, but not a big deal going w/ hub adapters.

Good Luck

Installed 73.1 to 66.1 hub centric rings and it seems to have done the trick. Alignment tomorrow!

Work wheels stock bore for 5x114.3 bolt pattern is 73.1mm, btw, for reference.

Nice to hear, doesn't take much to get a vibration. Should be really happy after your alignment.

Alignment done this weekend. The shop that flawlessly mounted the tires to wheels, did the alignment. They were super meticulous, very careful, and true car enthusiasts themselves.



Toe in spec without any aftermarket alignment bolts/arms. Camber may be tough to get in spec given the wheel's width/offset. It may rub if we try to get closer. Overall, very pleased with results. I don't believe I should experience any crazy camber wear.

Front Left:
Camber: -2.6* (out of spec)
Toe: 0.07* (in spec)

Front Right:
Camber: -2.6* (out of spec)
Toe: 0.05* (in spec)

Front Cross Camber in Spec
Front Total toe 0.12* in Spec

Rear Left:
Camber: -2.3* (out of spec)
Toe: 0.13* (in spec)

Rear Right:
Camber: -2.0* (in spec)
Toe: 0.15* (in spec)
