Just installed 10" C4 spring bolts
I should have got these a long time ago, instead of buying the 8 inchers..these things really dropped the rear to match the front nicely.

17s right now..i'll be putting the 15s back on tomorrow, because i got to take it to the alignment shop next week. Still looks like theres enough clearance though..i'm running a 7 leaf steel spring.

I still got to go down some, and i have plenty of room for adjustment. 
my front fender sits at 26" and back sits at 27.25"..i think i need to bring the back down to 27" to get a good even spread between the front and rear. Not a good pic..its night and not very good lightening in my garage.

There's another similar posting on the C3 forum. I'd just like to add my opinion as stated on the other posting. (Hopefully I'm not getting to be too much of a boor here.) All this stuff about body height/ground clearance should have statements related to the suspension geometry. Basically stated, ---I think this is correct, is that the half shafts should be parallel to the ground with a driver and a representative fuel load in the car. My experience with 225/R50X17 tires on my 1968 Corvette with a 360# VBP spring is that the car is really low and the half shafts are parallel to the ground (Well my 10 inch bolts will need to be adjusted to ~9.5 inches to get the half shafts parallel.) I have 550 # springs in the front. I'll lhave to wait until I get the engine in to see what I have to do to trim these springs (if anything.)
..............Bottom Line. Do try to lower the car as much as possible. But do make sure the half axles are parallel to the ground when you're finished. My opinion.

Would 27 miles really cause a problem on the 17" tires? I would really want it all set up the way you will drive it - meaning that it be aligned with the 17's on it. Also, get the ride height correct before you spend money on the alignment. JMHO...

After my stance was adjusted, I cut mine down to about 9 inches.
They are quite noticeable from the rear, I may paint them black or something.
