I give up. Can not find any video for the rear suspension. I have it all together & it looks right ...... but. Help

Photos? Let’s see it. Especially the top.

They are posted in my build log. http://dfkitcar.com/forum/index.php...in-build-227-06-ss-2-4l-donor.1913/post-41937

Is this what you are looking for?

There is more at my AllDataDIY account.

The rear looks good from what I can see. But the shock height needs to be adjusted.

This is what I have..

Coilover Options

Honestly, I haven't paid a lot of attention in the past to the conversations about aftermarket coilovers since I was planning on using the donor struts. However with the rebuild, I'm 90% sure I'm going to replace the struts since one of them seems really weak on the compression (and causing a...

There is a ton of conflicting information on the spring setup. I have the #300 springs up front (as shown in the video) and the #400 in the back. Seems to make sense since the majority of the weight is in the back. Yes, I need to adjust shock height.

thats backwards. The 400s are up front due to shock angle. 300 in the back.

I agree. I understand your thought process Captain, however the angle of the front require a lot more spring that the straigh angle on the rear even though there is more weight on the rear. We have the 400 up front and the 300 in the rear and the fronts are almost too weak on rough roads with two people in the car.

 

[CaptFrank2001]

Right out of the video (#23). It says 300 right on the spring.

They need to charge the video

from my notes when I was building:

“400 lb springs go on the front and 300 lb springs go on rear. Weird. Since front are angled Adam said. Who would know????”

But I believe that when you use the factory struts. I remember talking with Lonny and he told me when I was upgraded to the coilovers that I need to move the front 300 to the rear and buy 400 for the front. I really questioned him just like you are and that was when he explained the angle of the front really needs more especially when going to the stiffer coilovers.

300 up front and factory struts give a softer suspension and the 400 up front and 300 on the coilovers on the rear give a firmer suspension.

Definitely 400 front and 300 rear. We did it backwards at first and it handled like ****. Just swapping the springs made a massive difference in handling. Have changed a lot of springs rates and things since then but getting the softer springs in the rear is crucial.

Go here and plug in some numbers and check the spring rate at 90 degrees. Then using same numbers change only the angle of the spring to like 45 degrees. This will help understand the angle figuring in on rates. Heavier springs to the front due to angle..
