I'm just thinking to install a composit spring on my'81,I have changed the original shocks with kayaba gr2.
I use the car just for a ride and I don't like the car when it's too stiff,I'm thinking to put the 300lbs.

About your experience this combo will work fine?

Thank you.

I would...but then the bolt head would be below the rim.

The longer bolt won't stick down farther. It will allow the back end of the trailing arm to raise higher, which then will cause the front end (connected to the body) to lower.

No it won't...it's position is defined by the bushing that's at the spring, which remains constant.

The end of the 10" bolt (not the head, it is up) will definitely be below the edge of the rim.

The bolt head is on top. This is the Bubba version.



An 8" bolt works fine.



I could lower the back a bit but with 235/60s it is OK for me. It would look much better with 225/70s but the tires on it are 80%. Why change?

Sorry to hear of your Dad's passing....Sometimes it is difficult to know what the real question is.

Yes, if you wish to present at shows as an original car leave as is. If you wish to drive then go composite.

Wow, can't believe I have to explain this. OK, if the longer bolt doesn't stick down further in relation to the wheel; how is the car lowered? Go out and take a look at your Vette. The longer bolt allows the spring end to go down closer to the ground which lowers the car.

But in actual practice, the change in bolt lenght, if done properly, isn't that significant enough that you'll get into trouble. Keep in mind, this rear suspension design has been around since the 1963 model year, without any major ride height adjustment issues....
