Solution for those with a sagging rear-end!

Solution for those with a sagging rear-end!
Like many others here, my car suffered from a sagging rear end. After I installed my H&R springs, the rear sat about 1/2 inch lower than the front and I couldn't stand it. I searched the various forums for a solution, and it appeared the only answer was "install coilovers".
I wasn't satisfied with the consensus answer of "install coilovers" since I have no intentions of tracking the car and I didn't want to spend $3000. So as I was standing in my garage after my spring install, pondering this problem, I looked down and saw one of the hockey pucks I use as pads for my lift. Right then, a light went off! Hockey pucks are extremely dense rubber that hold up to quite a bit of abuse with little damage. I have used them for years on my lift and floor jack and other than a few scraps and scratches, they're all in perfect shape with no compression or deformation damage.
I took apart my rear suspension and compared the lower spring perch to the hockey puck… It's practically the same diameter!
So, I cut one to my desired thickness using a bandsaw and drilled out the center to the same inner diameter of the spring perch.
I reassembled everything with my new spacer in place.
And the final results are perfect!
I drove around with these in place for a couple days to let them settle in, then had my alignment done. So far after about a month of driving (1,200 miles), they are still perfect. The car drives and handles great. I took them apart again to examine, and other than a very small amount of compression (maybe 1-1.5mm), there are no signs of deformation or splitting.
I'm curious what everyone thinks, is it mad genius or blasphemy!

Did you consider an additional spring perch for the top side where the spring makes contact?
I think a metal ring on top of the spacer would be the perfect setup to prevent wear and tear on the spacer.

Excellent idea! Having just come from the Jeep world, we use hockey pucks for bump stop spacers all the time...great job! I think I might do that too. I don't like the rear end squat either...

i have called a few CNC shops around and left messages for an estimate this morning. Also called some suspension guys that do 4wd, i mentioned Porsche and they said they couldn't help me.
I got ECS tuning wheel spacers 17/23mm. i tried the 17 on the back and still wanted more. i tested them on the front and that were they stayed. i bought the 23's the same day and fitted them the next. i have a little rubbing over bumps. yesterday i rolled the inside of my fender a little. someone said that it had already been done a little before.

Thanks Eddy for the right direction. I found a couple of online metal places and ordered them cut to size instead of going the CNC route. Re CNC, no one called me back, i guess too small job??
The pieces ended up costing me $18 for both and $20 for shipping. The one CNC place i contacted and got through wanted $125 minimum.
I am going to have to wait another couple of weeks because of backlog at the plant and for it to be shipped ground.
THANKS AGAIN!
