FAQ: Aftermarket Lowering Springs

Robo,

The handling must be great, but doesn't it ride like a buckboard? My car on the other hand handles and rides like a mattress right now.

Say,for all you smart guys out there,If my current springs are 450pounders over the oem of 154lb, what % increase is that?

There's no crazy formula in this.  It's straight up math.

(450/154)-1=1.92, or 192% over stock.

haha! I like that.I was king dummy at school but I sure could skate fast!

It is.No,she doesnt handle at all like that.At first it felt different,but it now seems quite normal & the Riv is very tame at all speeds.She kinda hits the expansion joints and the such at very low speeds but at higher speeds she floats.weird.
Go to afcoracing.com and check out their spring chart and cut it in half according to your vehicle weight.Talk to the afco guys and come to a determination.I would never ever ever go back to stock.My driving pleasure has increased with the 192% over stock rates to a prodigious degree.Its just ridiculous! Your deciding factor in this case is the amount of spring rate your shocks can handle.If your shocks are shot,you will pogo all over the place like an old van with clapped out 25 year old monroe shocks.Not good.If your shocks cant handle the extra weight,they will be unable to control the Rebound! this is not good either.Your shock may wear prematurely. Call your shocks manufacture and inquire how much spring rate your shock can handle and buy up to it's limit.Simple.

The saga of lowering springs continues... Can anyone give me a published cross-reference to the p/n tags that are on my stock front springs - PN 22132527 and SMF under the number. Can't find the number or specs anywhere for comparison to the Spring Specialties specs taken from 22192716 - the only number they have. Anyone?

Thanks, Richard

I don't think you're going to find specs on them anywhere. The best I can do is look them up and see what cars they were put on, and what years. We don't even have specs at the dealer.

Thanks Scott - any information will be helpful

Well, I just looked up the P/N. 22132527 isn't a good GM number....

That's the problem. This is a factory original low mileage car and that p/n came right off the tag on the front spring...

What kind of car? Year?

why dont you just take Moog springs part number for your year and give CSS those numbers?

What do you guys think of these? I've never heard of the brand, but the eibach springs for the Seville fit, right? So shouldn't these?

http://www.clubgp.com/newforum/tm.asp?m=5924565&p=1&tmode=1&smode=1

Im not sure if theres any difference between these and the Eibachs people put in their Rivs but I would imagine they are the same. Might be a good deal for someone who cant find a set. If you can get an account activated on ClubGP anymore, that is...

After doing a bit of digging it looks like they might not work. Part number for the STS spring kit (the same one we need) is 3872.140. The kit he's selling is the 3865.001. That doesn't mean that they won't work, it just means that they probably won't.

No, they won't fit a G-body.

  

Sorry, for some reason i didnt see you guys replies. Matt and Jason, were those replies to me or
Dave?

OMG Tyler you've done it. You've found an alternative to the Eibachs. I'd like to know as well if they will fit a Riv.

Those also appear to be impossible to find though...

They were replies to mine and then got merged to this thread!

Dave where did you get yours? I assume the ones Tyler posted are out of stock as well.

One of you dudes has got to do the coil over mod! Robo is still the only dude to have done it, but he never shows any pics of the thing.. you'd think he'd show it off if he really dropped it a couple inches..

I'd go for the F41 springs if I had no other option. And Abaddon is the only dude to have done that, right?

What's the advantage of the F41 Springs? Aren't those from a PA Ultra? Wouldn't that sit even higher?

I'll take a pic tomorrow.
