Rear Spring Swivel Cups

[racing08]

Is it worth it to use swivel spring cups on the rear of an IMCA Stock Car? Will they actually free the suspension up any?

[fastford]

it will free the suspension up some , also a spring works best when kept strait and not deflecting ......

Ok I didn't know if the metric 4 link had enough movement to make them worth while or not

[fastford]

the metric 4 link in stock form will bind sooner than a system with a panhard bar , but as competitive as these classes have become , i think every little bit helps.......

no not needed or good on the rear, they will cause you more issues than doing good.
