What's the difference between getting the FCM threaded sleeve set vs getting the cheapo ebay coilovers and adapting the threaded sleeve?

ebay and Ground Control sleeves are for 2.5" I.D. springs.

As stated earlier, he has a kit for the standard 3.25" I.D. springs.

Shaikh does the research, uses high quality parts to make his kits, and above all else, he knows Miata suspension: from compression dynos for bumpstops to camber curves at random ride heights to shock dynos. So if you have a question for him, he'll easily have an answer. The guy does his research and strives to provide innovative and high quality parts for those of us who prefer to think outside of the FM box of most M.net members.

(nothing against Keith and FM btw)

I mentioned this kit in the Coilovers Suck [email protected] thread. Good stuff. If you have questions, give him a call. He's quite friendly and informative.
Oh, and I'm not affiliated with him either.
And sorry for the repetitive post...lol

stuff looks solid. although the price is up there and near GC price without springs. I'm not sure which real good quality spring you can get out of the 3.25" except for FM. I have S-techs and I'd rather just sell my springs and get GC overall.

Yeah, I have stock springs (shoot me) and can't see myself buying springs softer than FM's...
Actually thinking 400/325 lb/in (close to 7 and 6 kg/mm) would be best suited for my driving and preference, but I'm unsure what length springs to buy.

I'm not the biggest fan of FCM stuff, but this I think is going to be very useful tool to have, and I love how he has massive amount of options, and not like GC, where you have to buy the whole kit. For a low budget minded owner, this is great, as now corner balancing can be achieved, and it opens the door for more ways to screw it up :D..........

Nice to have another alternative to buying GC's for those who already have stiff enough springs.

So the 3.5" perches work with the stock springs or stock style springs, so you would use FM, Tein, etc. right?
But with his 2.5" perches for "race" springs, what kind of springs would you need? Are these the same size as the GC uses?

yes, 3.5 is the normal size for most lowering springs, but make sure.

2.5 is for race springs, which is what the GC kit uses. If you look at race springs, you have lots of options. From length of spring, to the spring rate. Popular names are Eibach, and Hyperco. Tein has them too, along with Swift, or basically any well know coilover maker has them, if they don't, then it's a good sign they're coilover isn't too serious, or isn't well developed :(.

Hey guys! Jumping in a bit late...

It's actually 3.25" but you all know me to be a stickler for details ;) Yes, all lowering springs for the Miata are 3.25", to fit the stock perch. Tein S-tech, Racing Beat, Eibach, Tokico lowering kit, stock, FM - all will work.

The 2.5" kit will take any race spring, including some that are also excellent quality but much less expensive than Eibach, Swift, or Hypercoil. The QA1 available from Summit Racing and Suspension Specialist Springs avaialble from PitsStopUSA are my top choices. I just got a batch of QA1 400 7" and 300 7" springs for a few customers getting complete coilover kits.

I will be offering springs to make full kits but don't want to carry everything under the sun. Easy enough to order and have it delivered in a week, that way it's exactly what you want. If you buy a complete coilover kit, including springs, perches and FCM mounts, you'll get bump stops thrown in for free!

I'm glad others appreciate the variety of options! I'm going to be cleaning up the website to simplify the interface but I'm happy with how it's progressing.
