In this post you stated that you used 720# springs and 320# springs. Which ones were on the front and which were on the back? http://www.camaros.net/forum/Forum7/HTML/000870.html

The 720 is front 320 is rear.

Check their web page. http://www.guldstrand.com/

If the spring is not there, I'm sure they can make one for you.

chicane 67 might design one for you, send him an E-Mail and ask.

Yes, the springs should still be available. Although, there are three different configurations, which would be determined by the front spring rate. There is a matching rear rate for each front rate that he sells, to maintain balance. The rear springs from Guldstrand might be costly, but worth the moola.

I have made a couple of changes to his original spring design to get the spring closer to what is needed in ride height and rate changes. I had my springs done by a local shop and they were less expensive and come with a lifetime warr. That and my configuration changes to the spring design, over the years, I have finally come up with a spring which met my ride height and rate needs for my application. REMEMBER, that Guldstrands springs are sold outright, with no garr. on height. To lower the vechicle, you wil need to purchase the lowering blocks as well.

The lighter FIA springs rate about 260 lbs.

With the spring design in hand you can just about make any rate change just by choosing the individual leaf thickness.

The 320# is a 0.380 main
0.380 second
0.360 third

The 260# is a 0.380
0.360
0.360

The 220# is a 0.380
0.360
0.320

And with this you can essentially change the ride by putting in Teflon liners (full) or just teflon pucks. There are so many different configurations its silly.

But Guldstrands right out of the box will work.

I am just very picky, spent a lot of time on the scales and driving the car sideways to figure all of this stuff out. I have 6 pairs of springs.....just to tune the car. But the ones in the car now, are the best balance I have found yet, and they havent been changed in 5 years.

Tom,

In the post that JVOLK81 mentions above you say that you run 16X8 wheels with 245/50 16's. What backspacing do you run on these wheels. I have a set of 16X8's I plan to install and am curious if 245/50 16's will fit. These wheels have 4.33" backspacing. Based on your fit, is this close enough to your backspacing to work?

Thanks,

Ray

With a 16x8x5 4 3/4 with 4 1/2" backspacing a, 245/50/16 fits, on all four corners. The only problem I forsee is that you may rub slightly on the inner fender. A 245/45/16 would also be an excellent choise.

My fitment works due to the above wheel and tire fitment, and, with the brakes I run (Baer 13" track PBR) I have to use a 3/16" wheel spacer on the front end ONLY (with a fresh pad, dont need it with a slightly used or thinner pad). With the spacer and wheel/tire combo, it does not rub with the alignment I run on the car.... The rear fits great.

With the rim you have described, it will most likely rub the inner fenderwell on the front, and it WILL rub the lip in the rear! So you may have to do a 'cut and roll' on the rear lip so not to cut up the tire.

Mind you that the fit does have to do alot with ride height and alignment. With a rim of 4.3" b/s, I would almost be positive that it will rub if the car is lowered.

Anyone?

Thanks for the input Tom. I figured the 4.33" backspacing may be a little less than perfect, but want to use these wheels.

If you are running 3/16 spacers up front, then that gives you effectively 4-5/16" (4.31") backspacing there, which actually is just a hair under my 4.33". Do your 245/50's on the front rub the inner fender? What about the bolt at the extreme lower rear of the front fender?

My car probably isn't as low as some here. I currently have stock 14X7 ralley's with 245/60/14's all the way around, which are about the same dimensions as 245/50/16's I think, maybe slightly narrower. They only rub the front on extreme bumps and rub the swaybar only slightly at full turn.

Anyone else running a 4.33" backspacing? I remember seeing a post once from I guy running 16X8 S10 wheels that were 4.33" backspacing, but can't find the post or remember what size tire he was running.

68ssconvert,
Keep in mind the early camaros had much more front wheel turning angle than newer cars.

As they went wider on tires Chevy reduced the amount of steering angle available to keep the front wheels from hitting the frame.

I plan on adding an adjustment bolt to where the factory steering stop is located on the lower A frame. This should keep the tire from hitting the swaybar or frame.

My 69 vintage race Camaro has this done to it.

I have a pair of 88IROC 16" x 8" wheels I can measure if you are iterested.
I also have 85 15" X 7" Z/28

If you like the ralley wheels, you can probably get some made in the offset you want.

68SS-

Actually, on the front it should be a great fit, but, my worry is in the rear. Even with the set-up I am running, the rear is REALLY close to the inner lip....and I cut the lip off to about 1/8" as to give myself more clearance, the only reason it does not rub is the Global West bushing/shackle kit (I believe p/n SH-102)those bushings really plant the rear end in the chassis.

As for the fender fastners, I use Allen type buttonhead fastners....they have a much lower profile than the stock hex bolt. (really saves tires).

I fully cycled the front suspension without the spring and it did not rub with the 245/50/16 Goodyear GSCS.

Thanks again Tom for the reply. I'll check the rear close when I test fit tires. I've been interested in Global West's bushings, I'll check on using them in the rear.

Are the button head fasteners commonly available, where should I look for them?

David, a correction to your comment to Tom -
Actually it is really great having ALL of you guys here. I'm really glad I found this site.

The fastners of question are/should be available at any hardware store or your local NAPA auto parts. Just take a stock fastner with you to get the thread pitch correctly selected.

I can't hold myself back!! Lets don't get all huggy/kissy here now guy's . What would the girls think, He, He!!!

Glad we all can exchange info and since I've peeked in over at Team Chevelle it looks like the A-body guys are the same way. Wonder about the X-body crowd. pdq67

Chacane67, do you know what rate the Global West front springs are? I had been told 500#. I have the S-2's. What are your thoughts on their L-2 rear springs? I was reading their setup recommendations.
