Coilover spring rate

[Captain Calais]

Got a question. Purchased a set of Viking front coilovers for my Cutlass. 450# spring rate. Put them on and now the car sits about 2 inches too high. I've adjusted the coilover to lower the ride height but no avail. Car has a Buick GN v6. Are these springs too stiff? The car is being used in autocross.

How come you started a second thread identical to the first one?

 

[Captain Calais]

No clue how that happened. Didn't mean to.

Viking hasn't said anything yet. Just thought I'd see what other GN guys are running with.

I have not seen anyone here with a GN running the Viking set up. UMI has a set to put on their Green Machine and shanghaismith installed the Vikings on his Olds...

Sent and email to my Rep and Vi-king. I hope to hear back very soon hopefully they will shed from light on this issue.

Thanks

Which kit did you order(Drag, Handling, xtreme-light,) ?With it being a V6 you may have needed to go with the 350# spring.

Thanks

Hey James,

Thanks for the help! I keep getting mixed responses from other outlets. Some say 450# is fine, others say that is way to stiff for a v6.

Viking actually just got back to me saying the 450# is not correct for a V6. So off with these and back to Viking with them, and a set of 350# on the way.

I'm just so confused because then again, so many V6 GN guys are saying they have 450# springs on thiers and they are running fine.

Eibach springs have a spring rate of 660 and they sell the same springs for all G bodies no matter what engine the car came with. Here's the listing for the 3803-140 Eibach springs...1978-1987 GM A/G-Body: Buick Regal, Grand National, Century / Oldsmobile Cutlass / Chevrolet Monte Carlo, Malibu, El Camino / Pontiac Grand Prix, LeMans, Grand Am

yeah I spoke to my rep and they said that 350 is V6 spring.

Thanks
