Lowered with Eibach convertible spring in the front.
Lowered with G37S coupe OEM rear springs in the rear.

Thinking about going back to OEM springs now...

 

That's pretty good wear almost across the whole tire..

Been doing some burnouts or the often occasional fast exit?

 

Looks like too much negative camber. When you replaced the springs did you get a four wheel alignment?

 

More than likely you'll need some camber help. You can use the SPC front camber arms, but they don't make the rear arms for the vert, you'd have to use the 4 bolt setup which consists of 2 bolts for the toe control and 2 for the camber arm adjuster. You have to use a dremel tool to elongate the bolt slots, but it's not too tough. Here's a link on that~ https://www.myg37.com/forums/brakes-...-template.html

 

Too much toe out wears a tire MUCH faster than too much camber.
Was an alignment done after having the springs replaced?

 

Very good even wear, but as other said, the toe being out of spec will lead to quicker wear. Thanks for the picture feedback on your experience with this setup. The eibach up front will run low height wise due to the vert weight, but front camber arms would address that, SPC or SPL , and I highly recommend SPL if you plan to track the car. SPC otherwise, but SPL gives a log of adjustability and if beefier.

 

how many miles did the tires last to get to this point?
