I still haven't had time to put the rear shocks and springs in, so today I decided to push the rear axle up by hand until it hit something. Guess what it hit! The gas tank!!!! For some reason there part of the tank flares out at the top right over the axle. That is the part that the axle hits. Here is a picture of the scuff mark the axle made on the tank just by me pushing it up by hand.

What part of the axle hit that? The beam that connects both sides? I'm hoping to get mine on the lift tomorrow to see what I'm hitting...

Here is a picture of the empty spring perches when the axle is touching the gas tank. The tape measure shows 6 inches, so if your springs and shocks can allow your axle to compress this far, you NEED bump stops!

Here is what the wheels/tires look like when the axle is touching the gas tank. These are 17" wheels with 205/50 tires. It looks sweet, but, something tells me that driving with the rear axle hitting the gas tank could be hazardous to your health!

The tank hits with the wheels only that far up?? Hmm. My rear tires are that "tucked" just sitting in the garage...

Yes, it was the beam that spans the middle. I looked carefully around the ends, and everything looked clear there.

Well, I guess I'll do what you did in the photos with mine and see what's what. I'll try to post photos tomorrow night.

Cool! I'll be interested to see what you find.

I also see marks where mine is hitting the gas tank. I put green tape over the marks for the pictures so it's easy to see where they are.
Passenger Side: Driver Side: This is the lowest point for me. I measured 11.25" center of wheel to the fender. My problem is, my rear sits at 12.5" So that 1.25" of travel seems easy for me to hit. I might have to install some bump stops... |

Last night I was looking around and found that summitracing.com has several styles of cheap bump stops available. With just a bit of fabrication, the should work fine. My first priority, though, is to get my coil-overs installed so I can get the car back on t he road though. My Dodge 2500 cummins is beast, but is a bit expensive to use as a daily driver!

This does not look good to me... Moving the front of the axle up puts the lower rear spring perch at a bad angle. You now have a lot of side loading on the spring.
On top of that the axle hits the gas tank? Either of the first two would stop me from doing this mod... But the bigger reason not to (for me) is there are almost no SCCA classes (until you get up to Mod - no, not Steet Mod - I'm talking full tube-frame Mod classes) that allow suspension pick up points to be moved. If you want to change the toe, install the shims.

For me the SCCA rules don't really matter since I have a Street Mod2 1972 240Z (thus the username/email). I'm just trying to make my daily driver fun to drive.
I do agree that the springs seem to have an awful lot of side load, which doesn't seem good. I don't think raising the pivot point is the CAUSE of the axle hitting the gas tank. That would be due to ride height & supnsion travel. The axle would still hit the gas tank if the lower pivot is used if the ridevheight is too low, or the suspension compresses too much. |

Well, the stock suspension already puts the spring perch at a bad angle. Moving the axle position up just puts it back to factory.
But yeah, the downside seems that it's hitting the gas tank. With the the axle in the stock position, it will NOT hit the gas tank. It only hits due to the axle being higher. The spot it hits on the gas tank isn't the side of the tank, but the TOP flange. |
