My First Mod ;)

I had a really tough time getting this done. First shop ordered Tien Basis coilovers even though I told them I wanted Eibach springs. My guess is they had the coilovers laying around as they told me there was no extra charge to upgrade. The bad news is FOR THEM is I knew they were not correct for my car as I have an X model. Definitely should thank those on the forum for teaching this lil newbie.

Second shop had a great the owner worked at West Coast Customs and he knew his stuff. After an alignment he got me back in spec with no issues. The ride is amazing. I literally cannot tell the difference unless I am hitting a big bump.

I really think Infiniti made a mistake not giving the X coupe this stance as part of stock. I now really feel like I own a practical luxury sports car as they would say. I hope I did not catch the mod bug because I can totally see how this can become addictive

Here are some BEFORE pics. Look away if wheel gaps make you nauseous

Nice first mod, too bad you had to go through some hassle though.
How long have the springs been on now?
And do you have the alignment printout?

Been two days Brad. Yes, I have the alignment print out. Do you want me to post it?

Next mod is to add more adjustment to camber F/R so you don't chew up your tires?

Maybe I'm not reading this correctly but my camber doesn't seem to be bad after alignment ie. Current Measurement Pic.

I'm no expert on alignment numbers, but when you deviate from spec, you get more tire wear. If you're driving roads where you can actually benefit from additional negative camber then it's a non issue. If it's your daily driver, then consider what uneven tire wear will cost you in the long run.

Looks really great Jeff I told you not to be nervous and that you'd end up falling in love with the car X's 100000 with the drop. I can't wait to see the new wheels on this setup as well brother

I have an awd with a staggered setup on my car with the same eibach drop and never had any cambers, except the oem ones, and have never ever had any tire wear issues happen camber kits really are mostly used for when your slammed on coils and not a conservative drop like eibachs. I mean it's been done clearly and yes would help but it isn't 100% necessary in my opinion if you get your alignment specs correct.

Yep I finally did drop on Eibach Springs. Was a headache though as a few shops jerked me around. Also I found lots of places won't touch lowering springs.

Judging by the numbers posted, I would expect to see some uneven wear in the rear first. A full degree of camber is quite a bit.

Specs are shown on your printout, it's the min/max for each angle.

I had some uneven wear of my own, fully stock suspension. One rear wheel had toe out of spec slightly, other had camber. Result was progressively more wear on the outside of the tire than inside. By 16 or 18K miles, about 2/32" difference in wear from inner edge to outer edge. This was on summer tires, all season would probably take longer due to harder compound.

Now, this is a X model so full square setup and rotation is possible. On the S with the staggered arrangement, only side to side was possible. I had an alignment done last fall and will be getting new tires mounted in a few weeks. I guess we'll see in year if wear is even.

There's no canyon roads around here. Only corners we have are on/off ramps. So little benefit to be gained by excessive negative camber (which helps in corners).
