Please post your spring combo's that work well here.

1. Tell us if you have a Big Block or Small Block engine and any heavy options like Air conditioning.

2. Spring rate in lbs/inch, part numbers & MFR.

3. Measurement from top of wheel well opening to center of hub. This dimension is best because it is not influenced by tire diameter.

4. Post your wheel and tire sizes/offsets and a photo if you can.

Let's keep the messages short and sweet and just a pic or two.

Here's a link to a good discussion about 6308 and 6320 front coils: http://www.camaros.net/forums/showthread.php?t=110202
Thanks, David

Re: What springs work? Post your combo's here!

I have a 69 camaro coupe with a 350 sb. The car is an original A/C car but does not have the A/C parts currently on it. On the front I have Eibach 1" lowering springs (Jeg's # 369-3848.120). My rear was a mono leaf, but put on the 3 leaf mono replacements from (JCW # ZX942669X). My measurement on the front is
13 1/4". I will edit my rear measurement in when I get it. My rear measurement is 13 7/8". My wheels are TTII's 17x8, 4.75 bs, 5x4.75 front, the rears are 17x9.5, 5.5 bs, 5x4.75/ The tires are Kumho 235/45/17 front, 275/40/17 rear.

Re: What springs work? Post your combo's here!

I have a '68 RS Coupe, small block/iron heads equipped with a steel blowshield/McLeod adapter plate/T-56 and no A/C.

Dennis, I contacted Hotchkis when I installed the 1607's in my '68 and they told me that they are about 600#/inch for small block and 620#/inch for the big block version. Not positive about the rear rate as I have a modified set of old Rancho Challenger GTS III springs in the back. The blacksmith that de-arched these springs to set the ride height guesstimated them at 200#/inch.

Front:

Springs - Hotchkis - 1607F @ 600#/inch
Wheels - Weld -Draglite XP 191-16348, 16x8 w/4.625 Backspacing
Tires - Yokohama A032R, 245-45-16
Hub to fender lip - +/- 1/8" 13.5"

Rear:

Springs - NOS Rancho Challenger GTS III @ approx. 200#/inch De-arched 4"
Wheels - Weld -Draglite XP 191-16348, 16x8 w/4.625 Backspacing
Tires - Yokohama A032R, 245-45-16
Hub to fender lip - +/- 1/8" 14.5"

Re: What springs work? Post your combo's here!

All I know is.....springs are driving me crazy. I replaced my front springs yesterday and they are lower than the ones that were too low. dammit

Trial and error is not going to work....too hard of job.

At least I still have 10 fingers and not much blood was lost.

Not a happy camper. But I'll get it right sooner or later.

Re: What springs work? Post your combo's here!

i have a 69 with a sbc, aluminum heads, water pump and intake manifold. has headers, no air conditioning compressor installed. car weighs 3420 lbs w/o driver.

front: global west S-2 springs, 500 lbs/inch linear rate, claimed 1 inch drop. wheels are 17 inch wheel vintique steel rallys (measure 18 1/2 inches lip to lip), 17x8 with 4 3/4 inch backspace. tires are goodyear f1 gs, 245/45zr17's. measures 12 inches from hub center to fender lip, 25 inches from ground to fender flare. photo: http://i175.photobucket.com/albums/w154/guccieng/119_1916.jpg, http://i175.photobucket.com/albums/w154/guccieng/119_1918.jpg

rear: global west L-2 with delalum bushings and shackles. claimed 1 1/4 inch drop. spring rate unknown (about 175 lbs/inch, or so i've heard...). wheels are 17 inch wheel vintique steel rallys (measure 18 1/2 inches lip to lip), 17x9 with a 5 inch backspace. tires are mickey thompson et street radials, 275/40zr17's. measures 12 1/2 inches from hub center to fender lip, 25 1/2 inches from ground to fender flare. photo: http://i175.photobucket.com/albums/w154/guccieng/118_1891.jpg

personal comments: love 'em. the front and rear work well together. stance is spot-on what i was looking for; low but not riduculous. nice ride, not harsh. combined with hotchkis hollow 1 1/8 sway bar with poly bushings, nice ride over single potholes as well. not sure how i lived without them!

Re: What springs work? Post your combo's here!

68SS 350sb no air, ordered SB springs from firewheel classics, set her up about 3" too high. Re-ordered from another vendor, same story ??? Cut one coil off the fw classics and it set down perfectly. Gabriel gas shocks up front and gabriel red ryders (old school but works) with the stock rear multi-leaf.

Fender lip sits about 1" above tire, 225-70-14 BFG TA tires all around, factory 7" rallys. 1.5* caster, 1* camber, zero toe in. Nice setup for a driver.

Re: Front Spring Recommendations

New springs went in this weekend. Bought a set of Moog 6320s this winter, and finally got good enough weather to spend it laying in the driveway. Found some interesting things while taking the old springs out. I had a Moog 0638 on the drivers side, and a 6312 on the passenger side, and I've had the typical drivers side lean in the car, with the drivers side being about 3/4" lower than the passenger side in the rear, for as long as I can remember. Lesson learned, check the part numbers on both springs when you are replacing them

After replacing the springs the bottom of the wheelwell opening on both front fenders are 13" from the centerline of the wheels (25.5" above the ground) and both rear wheelwell openings are 13.5" above the centerline of the wheel (26" above the ground) and everything is level again. The new springs raised the car about 1" over the old ones. The very top of the front tires (F70-14 Ployglas belted tires) are just about level with the bottom of the wheelwell lip, but when I switch back to radials the will probably be about a fingers width gap over the top of the tire.

Took the car out for a quick spin around the block and its like a completely different car now, much stiffer, and nowhere near as squirrelly as before. Next project is a new set of rear leafs since the ones in there were put in by me in 84 and are now older than the originals that they replaced.

I would say that the 6320 moogs are just about the perfect spring for a small block convertible RS with A/C.

Re: What springs work? Post your combo's here!

Don't have a picture post other than what linked to my signature, but I am still running the GM off road road springs from 1969, # 3848989, its a 500# rate spring. Installed these two days after I recieved my car in '68.
Rear are the stock 5 leaf springs on poly bushings. I just removed the lower spacer short spring and installed a # 3 helper leaf out of another batch of SS 5 leaf spring set. I tried to install the entire 5 leaf spring set but the car set too high. Koni's in 4 corners.

Re: What springs work? Post your combo's here!

I recently changed mine to a spring that was cross referenced to the MOOG 6308. I went to my local NAPA parts guy in Canada, and he cross referenced them to their part number. They are made by Dana, and I was able to measure the uncompressed height, and the OD of the wire and they were identical to the 6308s. They put my car right where I want it and this is the part number. I will post a before and after shot. Handling is superb.
Napa 277-1984

Re: What springs work? Post your combo's here!

Shore, I don't have pics. Mines a '69, with the difference in the wheel opening radius it would be hard to draw a comparison.

Floor to center of wheel opening is 25.5"

1. Tell us if you have a Big Block or Small Block engine and any heavy options like Air conditioning.
69 Convert - small block - aluminum heads - NO AC

2. Spring rate in lbs/inch, part numbers & MFR.
Hotchkis 1907F front and 2407C rear

3. Measurement from top of wheel well opening to center of hub. This dimension is best because it is not influenced by tire diameter.
12 1/4" front and rear

4. Post your wheel and tire sizes/offsets and a photo if you can.
17 x 8 front with 4.75 BS 235/45-17
17 x 9.5 rear with 5.5 BS 275/40-17

Additional - I had to use a 1/2" spacer under the driver's side front coil to get it sit evenly in the front. Global West wants $15 ea. for this spacer. I found the IDENTICAL spacer at my local spring shop for $6.

On the rears, I made some 3/4" lowering blocks to get the car to sit where I wanted it.

I also used SC&C Strret Comp Stage 2+ package and a Hotchkis 1 1/8 hollow front bar. . I never dreamed this old heap could handle as well as it does.

Hi Dennis,

Are you using these rims and tires on the rear of your car with the stock inner wheel wells and the leaf springs in the original location?

Thanks,
Joe
