Raffaelli Posted January 12 Report Posted January 12 1994 Lumina Z34. Already have the rear end taken care of, and I wanted to beef up the front. Anyone know of the firmest springs I can get for the front of that strut design? I think I read something a while ago about 1996 Monte Carlo 3.4 front springs would be it. Suggestions? Quote
55trucker Posted January 12 Report Posted January 12 There are no longer aftermarket *performance* springs manufactured for the 1st gen W's, if you've got the FE3 suspension under the car then you've already got the stiffest springs available. I take it that you want lower the front to match the dropped rear's ride height? Raffaelli 1 Quote

55trucker Posted January 12 Report Posted January 12 The springs are not a *Chevy* thing....all 1st Gen W's with the FE3 got the stiffest coils available. What's under your Z34 is also under a GP with the FE3 suspension. Raffaelli 1 Quote

Amanita Posted January 12 Report Posted January 12 (edited) I did a bit of digging on this a while ago and unfortunately if you want to change anything about the suspension rate in these cars now past what FE3 gives you'll either need to contact a spring shop or figure out how to fit coilovers on the car. There were custom coilover mounts available here but the last batch sold out years ago. I'm sure there are springs out there that fit the car and provide a stiffer rate than stock but as far as I'm aware nobody has come across ones that fit.

55trucker Posted January 12 Report Posted January 12 Spring shops can only install what's available in the aftermarket, & FE3's are not one of them. The springs availability is *generalized*, only the basic spring would be available. Raffaelli 1 Quote

I should have specified contacting a spring shop that specializes in making custom coil springs like this website https://www.coilsprings.com/classic-car-coil-springs No idea what numbers you'd have to give them, I wish I had a spec sheet from a discontinued aftermarket performance option for reference but I imagine those are very hard to come by.

SuperBuick Posted January 12 Report Posted January 12 Automatic equipped FE3 springs from a 3.4 DOHC car seem to be the stiffest. The manual trans springs are slightly less stiff (as compared side by side, and they have different part numbers). In other words your automatic Z34 has the stiffest ever available factory.

Raffaelli Posted January 12 Author Report Posted January 12 Going by the RPO sticker, the fronts a little confusing. I’m assuming BPY code for the front springs Quote
