Update!
Not much happening this winter. I'm looking at getting a set of track only wheels, 19x10.5 front, 19x11 rear. Also looking at Bridgestone RE-71R 305 tires all around. I have new, longer wheels studs to install. No changes on the Z/28 suspension. I'm still running the OE 1LE rear bar which is bigger than the Z/28 rear bar.
The 2017 1LE is in the back of my mind. Guys who now own the Gen 6 1LE and previously owned a 5TH Gen are saying positive things. One comment was that it is a big change. My bro-in-law has a Cadillac ATS-4 with the Performance Trim (not a V), 2.0L turbo. I fell in love with the razor sharp chassis and awesome steering on this car. Now we all now know the Gen 6 is built off the same chassis (Alpha). I previously said then to my Bro-in-law is if the Gen 6 Camaro has the great steering of his car and add the V8 it would be perfect. Fast forward to the recent 2017 1LE reviews and that same comment has been said.
I wish i could keep my 5Th Gen and still get a 6TH
