question about front tubular control arm upgrades

I was reading some of the upgrades guys have done and seen the option for MM SN95 tubular control arms and see according to the website it requires a coil over conversion.  Is this mandatory for the 88 Tbird or just for the SN95 Mustangs?  That or was it even really necessary, and when you guys did use the Tubular control arms was the camber plate necessary as well?  I see on their website it says there are clearance issues.  

I was just looking at tubular control arms because I'm rebuilding the front , section by section.  I figure buy the time I try and source replacement lower control arms or rebuild my old ones it is probably just more time effective and a cleaner install job to buy tubulars  I already did KYB shocks and happy with the ride and height but also not wanting the hassle of coil overs, whereas I am just looking to replace worn bushings and ball joints.  Curious on what the interference is overall. 

Thanks everyone.

To answer your first question, a coilover conversion is mandatory if you install the MM tubular control arms. The MM control arms do not have a spring perch. For your second question, I would say the CC plates are mandatory as well. MM has a lot of good tech info and I'm sure they have some info on requirements for the CC plates. I believe the interference they are referring to is if you go with the offset control arms. The offset CA move the wheel 3/4" forward in the wheel well. This combined with say, their tubular k member (another 3/4" forward for 1.5" total) could cause some tire clearance issues. The non-offset CA with the stock 88TC subframe put my tires in the stock location. I now have a tubular k member and with 235-45/R18 tires up front, I'm getting real close to having an issue. I'm also running a full 96 cobra brake system so the spindles move the tire out of the fender well by 3/4" as well. As you can see, I have gone down the the rabbit hole of mixing and matching various parts.

With the above being said, I love my coilover conversion and couldn't recommend it enough. MM will work with you to recommend a spring rate that is appropriate for your application. The coilovers offer so much adjustability and to be frank, provide a higher performing ride than the stock or stock replacement shocks/struts can ever offer.

Yeah thanks John, when I typed this post I had forgotten that the spring was separate from the shock on the Tbird.  It's been a while since I swapped the shocks and been working on some other stuff so just got my cars confused.  I was thinking they were already a strut spring cartridge so now that I realize there is no spring pocket on the MM CA's it makes sense.  Thanks for the reply.
