HELP Suspension Spring's

[Griffin84ss]

Hello all I am new to this and i am about to order a set of spring's moog# 5660 for my 84ss that's stock and theses are recommended by another member on here and would like to know if these are correct? Thanks for any information

There are a few Moogs that fit- 5658, 5660, & 5662. It really depends on your goal, however, I think you'll like the 60s.

Thank you. Mr. Fleming442, Mr.pontiacgp I'm not trying to make it pro touring racing I just want it to Handel really well so any and all information and or part #'s will be greatly appreciated. Thank you guy's again

Moog part numbers:
5658- 530 lbs/in
5660- 598 lbs/in
5662- 648 lbs/in
5664- 707 lbs/in
Rock shows the 62s as 748, but that doesn't make any sense given the part number to rate increase so I changed it to 648. Keep in mind that the stock replacement 5606 is 350 lbs/in.

Keep in mind those thirty plus year old springs have sagged over time,even new stock replacement ones may make it sit higher than it is now by default only.

Thanks for all the help I think I'm going to go with the moog 5660 ones and get the pro forged .5 tall balljoints with the micro cell ZQ8 bump stops. I think this is a start if anyone sees a concern please advise. Thanks in advance.

.....and what is minimum wheel diameter before it hits the inside of the rim?

.....and what is minimum wheel diameter before it hits the inside of the rim?

The Tall lowers shouldn't hit the Rim. Tall uppers might make the arms hit a smaller diameter rim, however, especially when turning tight.

You can see there is lots of room for a tall lower BJ, but the dust shields need radiusing, and the lower A-arm lip may need to go. The 12" and larger Brakes generally space the Rotor out 3/8" so the arm's lip usually doesn't hit the rotor, just the dust shield.

i couldn't tell if you're looking to lower the car @ all Griffin84ss but if you do go with the taller lower bj's it does lower the car slightly.

MELLOELKY I was advised to use this setup and may have to cut the spring's a 1/4 at a time to stiffen up handling and lowering it at same time if this isn't correct please explain. I guess I'm am going to have to go with 12" brake upgrade with a 17×8 rim size hopefully it will work
