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!

I love home made solutions
. Especially with something like this I can imagine the face of the next guy that buys your car and decides to take the wheels off for work or cleaning.

There is a certain satisfaction that comes with solving a problem with stuff you already own. Buying and installing parts is always fun, but creating something out of stuff you have lying around is a completely different level of enjoyment. Nice work.

Mad genius for sure. Of course, coilovers are still a better answer...MWAHAHAHAA.
But then I only paid $1100 for mine.
But seriously, perfect. You should drop a line to H&R. It was actually one of the reasons I went PSS9s, but back then I didn't know as much about the actual suspension build layout, and everyone raved about the (true) order of magnitude improvement in handling and ride with PSS9s.

Looks good! You'll have to give us a follow up 6/12 months down the road and let us know if the puck is holding up...

Keep an eye on them and if/when they start showing faliure, have the same things made out of aluminium or even steel. Any local machine shop can crank them out. Make a bunch and sell it to get the money back.
