It looks like it was one of perhaps half a dozen turbo LTZs built before the constraint. I wonder if it came with the five speed shifter knob?

Of course it does. GM did not sell any with the 5speed knob, they just shipped a few than got them off the market. There is a story about when a member came across one here on the forum. He even ran the gear shift through its paces with the salesperson sitting next to him to show the salesperson it had six forward gears. This is one of the reasons I believe the Sonic turbo LTZ lasted so long - waiting for the shift knobs.

Its over 39000!
Yo Danny5, can you take a side view pic at ground level without any downward angle (straight on) from both sides cuz it's very hard to tell how low it dropped since your car is black (the black tires seem to blend in with your current pics). Also, if I have 17" aftermarket rims will the tires tuck under more (less gap) since they're bigger than your 15" stockers or will it be the same?
Not the prettiest picture since it's over exposed for yah
The overall height of the 15s should be the exact same as the 17s.
You want to keep the circumference more or less the same, so to achieve that, you decrease your sidewall height by about 5 points for every inch you go up in diameter. Our stock tyres are 195/60/15, so that means 16 will be 55/16 and 17 will be 50/17 to keep the rolling diameter the same. Someone correct me if I'm wrong.

I think Danny meant the outer circumference of his tire is the same as a 17" wheels' tires outer circumference. He is saying that the way his car's tires look in the fenders are what the will look like with a 17 on the car (minus the lower profile tire and larger wheel).
But yes, you're right, you do drop the percentage to width to get the same overal tire height in a larger wheel.

Thanks bro, this^ is exactly what I was talking about, now you've convinced me to buy these springs & with the write-up you posted, it'll save me hella $ on the install if I do it myself, win-win situation!

Installed this morning. So far high speed, low speed, and comfort seem to be unaffected. The rears bottom out faster on large high speed bumps, but I had 600lbs of people in the car on my rough road testing.
Cornering is the same as before, these springs are pretty compliant. I love the look! Rubber air dam is now 4" off the ground.
Anybody know stock height from hub to fender? Apparently I got my measurements wrong before I swapped it out.
I went from 16.5" front to 13.5", and 16" rear to 13". The before measurements are definitely wrong. Any stock height hatches want to measure for me?
They are going to vary from car to car.
Measured measured from ground through center hub to fender.
Stock height Lowered height
Front left 26 7/16" 25 3/16"
Front right 26 1/2" 25 5/16"
Rear left 27 3/16" 25 7/8"
Rear right 27 7/16" 25 15/16"

You can use them on your next set of wheels so that they are not wasted. Or, sell them to someone else on here with stockers that want a little more width.
