FRPP lowering spring replacement numbers

Hello everyone,
I'm looking to add this mod to my car. I recall reading a thread where the parts were discontinued, but there were substitute part numbers. I can't find the thread for the life of me. Does anyone know what the new numbers for the FRPP springs and shocks are?

Thanks!

Hey, check out fordracingparts123.com, you'd want to get M-5560-zx3b for the springs and M-18000-zx3b for the dampers. The springs are discontinued but you can still track them down places like this site for instance. Some people are buying the zxm1 springs instead using them with these dampers, but other say the springs are too harsh for those dampers because the springs are progressive and meant to be used with the more expensive zxm1 dynamic dampers... I'd got whole zx3b set I first mentioned from that site, it was the cheapeast direct bolt up option and I don't race so i don't need progressive or dynamic in my suspension :) they got to me quick with no issues- great site, and I love the set up. Just be warned, my camber ended up way farther out than what many others experianced, seems different for every car. Make sure you check your alignment after install and be prepared to need camber bolts or arms and some adjustment to the front. Hope that helps some! :)

Ford dealers have a d2d network (dealer to dealer) they might be able to track them down that way. Also try ebay. Many dealers list on there and is how i found mine.

I was able to swap mine out and had the dealer check the alignment and it never budged. I do wish i had a slightly different damper set up. I love the springs. To me they are softer than stock but are awesome on the track.

Pick up some spring compressors from harbor freight ($15) or borrow a pair from autozone. No special tools necessary and can be swapped out in a hour after you have assembled the new ones. I did mine in my pajamas on my living room floor.

Those springs you mentioned, the M-5560-zx3b, are they lowering springs? it doesnt say, but there are other springs on there that say they lower ride height 1.5"

Well, yeah. Basically there are two sets of springs from ford racing that you can use, the M-5560-ZX3B and the M-5560-ZXM1.

They both lower a vehicle approximately 1.5". The difference is that the ZXM1 type is a progressive spring rate spring designed to be used the the ford ZXM1 dynamic dampers. That set up is definitely more expensive and performance oriented. It's suppose to be a harsher ride, but better suited to track use...

The ZX3B type is the one that most people have used here. More meant for stance while maintaing much of the ride qualities from the stock suspension. Same ride height, just a more average spring type and designed to be used with the regular ZX3B damper set.

I went with the ZX3B springs AND matching ZX3B dampers because it was only $340 after shipping. Many people have said they are too soft, but for me- I found them to be a hair stiffer than my stock set, I can track around corners in the city better, and that's all I really needed. Mine settled to more like around a 1.7" drop despite the claimed 1.5" drop. Other have settled to more like 1.4"... Each car is different, where some people haven't had camber issues, others have- which is why said just be prepared. I wasn't.. And the extra expense and time was not something I'd planned on having to do after install. It took me about 400 miles to settle down that far... My camber was fine on install, not fine 400 miles later, basically.

The springs are available on eBay too right now, but they are $70 more than fordracingparts123.com. The site is operated by don wood automotive, which is a certified dealer of ford racing parts.. So don't worry, they're legit.

EDIT: let me correct myself... Those two sets of springs above are the two that are a direct bolt up from ford racing. You can really use any other springs with the right hardware kit such as the Massive Speed omni kit. BUT, those two are the only ones from ford that will go right on an 08-11 focus. You CAN use those springs with whatever other dampers, just be warned that the damper life will be shortened if you keep the stock type dampers with lowering springs. I didn't want to deal with that, so I got the springs and dampers to install as a set... Maybe that's why I don't feel like they're soft as some say? I don't know... I guess it's all a matter of opinion. I've never bottomed them out...

No problem! Haha... I waded through all the info on them for like 2 or 3 weeks before finally making the plunge. It was kind of hard to get it all figured out and sorted! In the end I still had to track down bushings for the rear- I didn't know I had aftermarket shocks on the back instead of the stock ones. If you're all still stock, you shouldn't need any additional parts to install the setup, though... And I didn't think I'd have camber issues because so many people here said they didn't with this setup, and... I did! I didn't have any issues with toe in/out though- which will really cause tire problems, BUT I've read about a *few* people having to get toe arms after the ford springs. So it's really case by case I think.
