Lowering Bottom Spring Perch

[AK260]

CO, you are most welcome and I’m glad to be of service. The offer is very serious, if you want them from here just tap me up.

The OD on mine was also 55mm hence why the gaiter has such a great stretch fit without over stretching. I spent hours on google before I came across something that was right or very close on all three dimensions. I also didn’t want anything too short that would pop off every time the car was jacked up.

Will do! Thanks for the support!

So I had mentioned above that if you are going to do the split collar perch support concept, you need to pay attention to the collar size.

This is what happens when you impulse buy 2" collars for your 280Z because you assumed they were the right size. They aren't. The 2" collars are too small and won't fit around the 55mm (2.165) diameter 280Z tubes:

Not wanting to admit defeat, I aligned the collars and chucked them up in the lathe and bored them out to fit the 280 strut tubes. Looked like this on the lathe:

In the end, I had to take off so much material that they got a little Swiss-cheesie, but good enough for the temporary use that I plan for them. Would have been better to start out with 2 1/8 collars instead of 2". I would still have had to bore them out some, but not as much and they wouldn't be quite so holy:

But in the end, here's what the bored out collar looks like on the 280 tube. Should be "good enough." :

Especially if you weld them into place when they are just right.
