My intial experience with the car, I wore though a two sets of rear tires for each set of front tires. I bought a new set of rims and put on the Nitto NT-01s
I then had the car re-aligned. These tires are all wearing at the same rate - all four are about to cord.

Would this indicate an alignment that promotes understeer?

Is this a good thing?

Where are the tires about to cord? Inside? Outside? Everywhere? What was the tire life cycle before and after the alignment (front and rear)? What are the alignment specs?

+1 what are the (new) alignment specs?

with stock alignment the R/F ratio is about 2:1;
with a proper alignment is closer to 1:1 than 2:1

(with 888s and MS cups and PS2s)

and btw understeer is not to be judged by tire wear..

you are working your front tires harder - implying either more front grip or more scrub

Here are my alignment specs:

Front Camber: Both Left & Right -2.5*
Front Toe: Both Left & Right 0

Rear Camber: Both Left & Right -1.9*
Rear Toe: Both Left & Right 2 mm (in)

Sway Bars: Front - 1 from full soft
Rear - 1 from full soft

The tires are wearing evenly but the outside edges are nearly corded.

Hot Pressures are 33 psi front and 38 psi rear.
Tire surface temperatures are:

Outside Middle Inside
Left Front 131* 144* 145
Right Front 133* 142* 144*
Left Rear 153* 163* 172*
Right Rear 168* 173* 181*

shouldn't the sway's be 1 from full hard not soft ??

^depends. I run full soft in rear and around middle in the front. I've found less bar in the rear is faster - but you really need to trail brake. A lot.
