Was the car driven before you took your pic and posted it up?

If the aluminum block is on the bottom of the spring and people are saying the car sits up high now, taking from the bottom and adding to the top is not going to work. You'll make it even higher.
I don't think Grumpy has driven his car either. Mid year guys use these spring with no ride height issue. I don't understand why there is an issue with a heavier C3. I sold 13 EZ Ride's to a builder in TX in the past year. He wouldn't come back if he had 13 different issues. I think part of the problem is that the car is put back done on the ground and guys go this doesn't look right. No matter what you do, after the car has been lifted off the ground and set back down it going to sit up. You need to drive the car around the block and than see how it looks from there and make adjustments.

No, due to the exhaust issues it has not been driven yet. However, when it was first set down the height was at 31 1/2. We rolled it ~50ft back and forth a few times and it dropped to 30 1/2. Based on your comment to Grumpy in earlier post I was assuming this is as low as it will drop. Are you suggesting it might drop more after it's driven? The decision point I'm at now is whether to hack up my exhaust and take a chance that I'll be happy with it, or return this spring and go plan B. (7 leaf steel).

Yes drive it. If you don't like it afterwards then send it back.
What was the factory ride height? Are you sure most people just aren't seeing old school fender gaps and comparing them to modern cars?
Out of the 73 shop manual - target trim heights :
rear ground to inner fender- 27.90 for the coupe and 27.58 for the conv
front ground to inner fender-27.75 for the coupe and 27.84 for the conv
Yes, drive it around and see what happens. Try and stick with the composite spring. Try other manufacturers. You can probably put some exhaust wrap if you are concerned about the heat. I have also read where some folks have there pipes up against the spring and have had no problems for several years. But in the long run, it probably wears them out faster. Which could cause it to lose its tension and lower...
For Van Steel...
I think you misinterpreted Black Dog - I think he was asking if the spring spacer could be removed from the top of the spring and then be placed underneath the spring instead. This would indeed lower the car.
Would there be any durability issues with this approach?
Yes Sir; I'm sure glad Van Steel has gotten in on this Thread, I wonder where the Mfg. Co's. who make these springs are at. I hope that their not all in China. I have a Original GM spring now. I would hate to have all these problems and not have the Mfg. Co's weigh in on what is happening. I would think a lot of other Members would want to know also. Have a great day. Gene

I imagine that must have been with the stock 215 (F series?) With the original 9 leaf and 235/60-16 I was t 29" even.
Yes drive it. If you don't like it afterwards then send it back.
Ok, off to the exhaust shop we go...even though my gut is still saying no....I'll keep in touch with progress!

Your correct I did misinterprete his post. Sorry Black Dog.
Not sure about the TRW spring as I haven't seen their center stack in a while but on the VBP spring there is a 1/2" spacer with a nipple on top of it. You could cut it down and put the thicker part on the bottom. You really need to make sure the nipple stays on top to keep the spring centered in the cover. I don't think the pad under the top spacer has a nipple on it. Again I apologize for the misinterpretation.

The VBP springs are made in house here in FL. The Hyperco springs are made by the OE manufacture for GM which is LiteFlex. LiteFlex has made the springs since day 1 for GM. They are US Made as well.

Is there any issue with heat from the differential getting to the spring to worry about ?

Dear Van Steel, can you please jump in on the other spring thread?
I'm going to transplant this post over there and ask a couple questions of you.
Up until now Muskegon is the only vendor willing to talk to us about ride height issues.

Yes Sir; I wish to Thank both Van Steel & Muskegon for their help in these two Threads. I am sure happy to know, that the majority of the Composite springs, sold, are made in the U.S.A.. Have a great weekend, Thanks for our freedom, provided by our service men & women. Gene
The reason I ask was the factory plastic springs had a composite pad between the spring and diff that if I remember right was called an insulator.
( I still have a few pieces in the drawer from the 3 bolt setup. bolts,insulator,spacer and 2 metal pieces that limited how far the bolts could torque down. )

Those numbers were based on the 225/70R15 tires that were on the 73...the first radials...and what you want to do when adjusting the ride height is try to keep the half shafts as parallel as you can to avoid wear and tear on the joints....
