our 79 regal has this problem with crushing the right rear spring it is probably three inches short after 3 races and showed up after our first practice a few weeks ago i have not pulled it yet .springs are new stock over the counter 14by 75..anyone who has seen the green 8 at kyle may have noticed it the last race .i know nick did from way up in the booth ... i have checked all the trailing arms and none are worn or bent as i can tell during the rear end change last week ..but then again i am not used to this chassis typ .tps ford leaf i can pick a problem easily .this one has me stumped .the springs front and back are stock .sway bar 1 inch not loaded ...

What is the spring rate and what is the motion ratio squared? Also, is it a pig-tailed spring? Is it mounted in a spring bucket with weight jacker? If not, how is it mounted.

 

If you don't want to give away all your speed secrets, PM with the info on rates and motion ratio.

the only speed secrets we have is in the driver and he aint talking lol.........

nick ill check that out when i unload it ...the bad part is we are limited to stock springs ..and this problem cant be fixed with just going out an buying racing springs out of the question . they are pig tailed and located on stock mounting points no jacks or spacers and such .. we really did not have this problem as bad last year .i dont know what changed unless the older original factory springs are a better steel ..ill check the thickness of an old set to the new ..but i know that is a grey area ..

If you have an older Moog catalog you really don't need to buy racing springs. They have (or at least used to have) every spring available for just about every passenger vehicle/light truck. Not sure about their newer catalogs, but the old one used to give spring free heights, spring diameters (both inside and outside), number of coils, wire diameter and rate. Everything you need in order to make the proper spring selection as long as you know what you're looking to buy.

 

PS Whoever borrowed my old Moog catalog and never returned it, please be a good guy and return it. Thanks.
