measurements on my nismo are

Front: 26 3/8"
Rear: 26 7/8"

So how does it handle differently on the track? Better or worse?

Is there any way you can post your alignment specs with the front/rear spc kit? I'm mainly interested in your camber.

Also are the spacers / camber kit installed in all of the pictures shown in the first post?

any issues using a car jack once you've lowered on springs..??

How does this overall shorter diameter of the tire effect your speedo? According to my rough calculations the front is about 10 mm shorter and rear 15 mm shorter in overall diameter based on OEM Advan on Nismo model, size: 245/40-19 (98 mm side wall height) to 265/35-19 (93 mm) and 285/35-19 (100 mm) to 305/30-19 (92 mm).

I lowered my 2006 350Z 6MT Touring with H&R springs and I had no issues using the OEM jack to remove the wheels.
