Rear Coil-Over conversion

[92turboLE]

anyone know who makes rear coilovers for a 92 grand prix sedan... my monoleaf is all cracked and broken and currently held together with a 2 dollar clap from the harware store... the monoleaf, when good, rode like shit anyway and i would like to do a coilover conversion in the rear and maybe lower it about an inch....

 

any good manufacturers or part numbers that i should look for???

 

thanks in advance for the help

1st: go here for LOTS of info on coilovers:

FFP & Held Motorsports are the only places that make them now i think. FFP is CO based i think.

and Held Motorspors:

i emailed Held about thier coilovers and they gave me some generic email reply back that didn't even answer my question. they were basically like 'go back and re-read our website'. ok so uh, fuck you too FFP coilovers are FAR superior to my TDC coilovers (TDC is now out of business), i'd recommend the Addco 7/8" rear sway bar, along with a rear STB with any coilovers since the monoleaf itself had alot to do with lateral support. and i definateley like my KYB rear struts. the front of my car is lowered with 1.5" drop Eibach lowering springs i got from TDC. they definatley didn't lower the car enough and i'm planning on cutting a 1/4 off the bottom of the spring. that and going from a 225/60 tire to a 225/55 tire should give me the stance i want. i hope.

there is also this option; a flex-a-form lowering transverse leaf spring. go here to read about it:

don't get your hopes up tho, i think it's either in the developing stage or they just now released it recently or something. i would want to see how low it gets the car before i bought the spring and the price. fwiw, i would rather have an actual lowering transverse leaf spring than coilovers. hopefully flex-a-form follows thru with a W-body lowering spring with preferably 2" drop or so.....or more

Actually I suggest you keep your monoleaf. You can probably get one from a wreck yard. They are far supperior to the independent suspension that you get with the coil overs. I have seen coil overs brake at the weld where people welded the lower part of the strut to the coil over system.

 

Just as a comparison after GM discontinued the leaf spring on the back of the W body they have transfered it to the Z06. I got a 2002 GTP and a 1992 GTP the 1992 GTP with the leaf spring will outhandle any heavily modified newer GTP on any track. I wish I had the mono leaf for the new GTP. I know cause I raced my two cars on the track.

 

Just my thoughts.

Corvettes have had fiberglass monoleaf spring front and rear suspension for a LONG time. Maybe since the C3 'vette, not sure on that, but the current Z06 isn't the first time they used it.

Yeah, the transverse monoleaf debuted in 68' with the 3rd gens.

You're probably right I have not looked at an older corvette only a Z06 so that's what I can say for sure. It was a supprise to see this in a sports car though. (after all the mono leaf bashing of the Wbodies that happend years ago)
