Spring location on rear of metric??

[racer21]

Just wondering if one is better than the other and what each does,in front of centerline,behind or just centered up on rear,thanks in advance guys!!

In front of centerline!!!!

[a1driver]

there is alot to be gained by spring location on the oem 4 link!

[a1driver]

well hot rod if you mount the lr spring in front and the rr spring behind whats going to happen? you go think about this and let me know.

[a1driver]

think about the rotation of the housing related to the centerline of the springs.........

[a1driver]

you're like talking to a rock, if you think your housing does'nt rotate we'll just stop right here.

simple physic,..newton's laws of motion,...every action has a equal and opposite reaction...you can look it up

i can explain it i just choose not to explain it to someone whose ego tends to obscure their thought process. much of what applies to 3 link suspensions converts to the metric 4 link too.

I do not have a metric car, so have never ran any motion paths on one. The only thing that will allow rotation of the rear end is one of two things.

1. Motion paths of the links themselves, like the birdcage rotation on a standard four link dirt late model.

2. Rear end rotation from torque... For this one to happen one or mor links must have movement. Leaf springs wrap, pull bar cars pull.

For a stock metric chassis you will get little to no wrap from torque, possibly a tiny amount from bushing flex, nowhere close to the movement of a pull bar or torque arm. If you get more movement than that you have something broken.

I did state I have not measured rotation of the rearend due to motion paths of the links, so you could possibly get a small amount of rotation from that, but this will not be on the scale of a late model.

Again, with all solid links you will get NO, NONE, torque rotation to index a spring.

Stock car do you have videos out there to watch,im new to all this and can learn more from seeing than reading,and I do like your comments on stuff!! Keepem coming

[twizted]

Ok I'll put in my 2 cents, this is the only stock metric 4 link video i have seen. Depending on the bushings and condition of them I could see a minmal amount of axle rotation and possibly a minimal amount of advange to spring mount movement. Final conclusion is that our class cant move suspension mounts anyway and on a 3400# stock car probably would have to be alot better driver than me to fell the difference in moving sping mounts on housing.

here is one way to get some movement from your rear end....LOL
