Suspension Springs
 

Hi all!

I am Matt with PAC Racing, some of you may know me or have talked to me. I am looking for some feedback/help from you guys. I have thrown around the idea of doing drag springs for stock, super stock and anyone who races a class that needs an OE style spring.

My question is, is there a need for us to start doing stock style suspension springs? Is there already a great line out there that does not need improving? If there is not, what needs to be done? Any help ideas would be great!

Thanks!

Matt: A lot of guys are using Moroso "Trick" Springs. Just take a look at their catalog and you'll see a listing. Question for you, why did PAC "supercede" the PAC1409 beehive? I used the PAC1409 with great success and you guys replaced it with the PAC1409X, which has a significant amount more seat pressure. Thank you.

Re: Suspension Springs
 

And invariably the ride height with the Moroso springs isn't right, so you have to cut them...and then they don't fit the pockets correctly...unless you cut a full coil at a time...

Yes Matt...there is room in the marketplace for an affordable series of springs to fit most popular applications. The Moroso line is a good place to start...

PM me if you want to discuss further...

Re: Suspension Springs
 

We decided to go with the "X" only series due to its additional processing over the standard 1409. The loads should only be 15lbs more. In all honesty, most people like the extra 15lbs. Are you having issues with the extra load? If we have enough people complain we may do a low load version that would bring it back to 150 @ 1.800".

Thanks,

I know what they are advertised as, but It's more like 20-25 lbs. more in actuality. I called and talked to Jason from your company about this in early April. Please bring back the original PAC1409. Thank you.

Tim,

This is the info I am after. It seems Moroso's "trick" spring is the go to spring. At the same time I hear so much negative feedback. We are searching for a product line that works the way it is supposed right out of the box. Now you did mention affordable. What is that? Our stuff would range in the 70-100 range more than likely. That is per spring too.

Thanks,

Jim,

I will have some discussions here and see what we can do to help you out.

Thanks,

Matt,

I can't speak for anyone other than myself...but I would gladly pay $70-100 per spring for something that works the first time.

Matt -

I currently have the Santhuff front springs on my stock suspension 1992 Camaro I run in SS/BS. As Tim said, the Moroso springs are difficult and usually need to be removed at least once to cut off a coil or trim. The Santhuff springs are the total opposite. Install and they are ready to go. I would say if you can make something similar to the Santhuff that do not require almost killing yourself to get the springs in, you will do very well.

BTW, your valve springs on our modified motors are amazing. Keep up the good work.

Re: Suspension Springs
 

I’m actually in the process of switching out springs and I totally agree with the Moroso needing to be cut to get a correct ride height, but don’t agree with the Santuff being a onetime fit. They use a smaller dia coil than the Mororso and they definitely have more stored energy, but using them on an early Nova really takes some finessing. Because the coil wind is so much looser, it makes them taller and in my case it had a tendency to bow under load. I know the early Nova/ Mustang is not the best bench mark to go by because of their set up, but it sure would be nice to have something in the middle at that price. Not a whole lot of options out there to choose from…..

Re: Suspension Springs
 

When it comes to coil springs, front and rear, we stock and sell products that already work, and are not super expensive. I dont want to speculate how much R&D Dad has done over the last 40 some odd years with nothing more than stock replacement components.

I would say unless you are going to be more specialized like the Moroso or Eibach, it would not really be worth your time with the R&D.

Just my opinion of course.

Re: Suspension Springs
 

Moroso front springs are all we have ever used...no idea where to start with the Santuff's. We have always had to cut at least one coil on the Moroso's to get a decent ride height and to prevent bowing of the spring. With that set there is always a probability of one or both springs collapsing...this usually happens soon after install if it is going to happen at all. The latest set has 1-1/2 coils cut...sagging a little now but still acceptable. About 1690 pounds on the front of this car w/driver and small block.

Re: Suspension Springs
 

It used to be that front springs were a one time purchase without much thought given to replacement. Moroso was the only choice forever. Observant racers have tried some alternatives that were much better than the typical spring that required cutting and often ended up too stiff. Different cars have different needs. While some cars have off of the shelf items that work, there are many cars out there that would benefit from a custom spring.
We tried different springs and found a set that was awesome for our car, but difficult to fit yes. I also don't expect them to last forever. Fresh springs of the correct size spring rate, etc have a place in the market. More racers are figuring this out, but not all racers have an alternative. If we can order custom springs at a reasonable cost, I think there will be a growing market.
It will require testing. Some people want someone else to figure their cars out for them on the internet and never test. Then they complain when others are faster.....:).

Matt, check your messages please.

Re: Suspension Springs
 

Hey I wanted to throw a little word out there that this year PAC is paying contingency for suspension springs as well as valve springs.

Also if anyone wants to try out some test springs we have a 17.5X3.75 with a 210 rate, let me know.

Re: Suspension Springs
 

Matt,

I would be interested in springs. The Moroso springs are not ideal in my opinion. This is from my experience with Fox body Mustangs.

Thanks for looking at a viable marketplace for your products.
