Yup!

Morning Guys,

Thanks for your interest.

I may have one prototype not yet assigned. I'll have to double check who's been chasing me and double check my count. I'll pm you and let you know

Worse case scenario, I'll hopefully have the next batch available before the end of next month.

Yes. The brace is designed to fit in the boot without compromising the back seats at all. It should sit parallel but offset a few mm from the backrests.

If the entire boot is needed to transport something large, the brace can be unbolted and removed. The advantage here is that the subframe mounts are still reinforced by the kits it is built on top of when the brace is removed in the event you need it out for a prolonged time.

I'll do a basic tack welded assembly when the first batch arrives and share an array of photo's showing how the tubes fit together as well as how it fits and occupies the boot area before sending any prototypes out for testing.

Let me know if you have any other questions!

I'm sorry to be lazy, end of the day here in Cali, but can you tell me what tools are needed for install? Or at least, will this be completely bolt in or is welding/riveting required?

All good Tbone,

For all kits or just the brace?

For the brace it will come in kit form and require just welding. It comes with plates with self clinching nuts pressed into them that weld onto the topside beam kit and front mount extensions kit and then the brace is assembled and welded together.

For other topside reinforcement kits, in addition to welding it is necessary to drill a guide hole through the subframe mount from beneath (guide and HSS long series drill bit supplied).

After that a hole saw is needed to cut a layer of sheet metal away to expose the top of the subframe mounts.

Other tools would be the basics, grinder and cutting disks, wire cup etc. Nothing overly complicated.

Every kit comes with its own spiral bound installation manual. The underside plate & topside beam kit manuals are 20+ pages and ~60 images. It's very thorough and am told easy to follow.

That helps, thank you. I guess I just don't know the nomenclature you've chosen for your product.

So I think I would want the full kit, but isn't all of it "top side" only 4 long bolts are going up through the subframe mount points and the holes we drill up through the bigger hole the saw made into your brace right? Everything else is above ground so to speak right?

Is it possible to view the installation manuals, that'll probably answer all of my questions - thanks for making that!

I have plates welded, no new cracks that I can see, I just want something to bolt/weld in to lock it all together and play the role of a strut bar as well which the full kit seems to do ala mason.

Sorry about the confusion.

In short, yes it is all topside excluding the underside plates.

Just to brielfy explain you've got underside plates (USP) which reinforce the subframe mounts beneath, the topside beam kit (TSBK) which reinforces the rear two mounts on the topside of the RACP, the front mount extensions (FME) extend forward off the TSBK to incorporate the topside of the front 2, rear subframe mounts and then the 6-point brace which is a triangulated structure built ontop of the TSBK & FME.

Hope that helps rather than adds to the confusion.

So continuing on the above, if you want the 6-point brace, you need the Topside beam kit (TSBK) & Front Mount extensions (FME) linked below fitted prior.

http://cmpautoengineering.com/produc...-frame-system/

http://cmpautoengineering.com/produc...extension-kit/

Regarding the longer bolts, only the TSBK includes extended fasteners as the rear mounts are under tension while the FME does not include extended fasteners but rather weld directly to the topwelds of the threaded insert.

The hole saw from above is to provide a better fit and finish for the rear 2 mount kit and for the front mount provide a hole for the tubes to drop down into to contact the threaded insert.

If you want to shoot me an Email I certainly can share a PDF copy of the installation manuals for you to peruse. I suspect it may answer several of your questions.

E: info@cmpautoengineering.com

I'm also open to constructive criticism if you believe anything is not sufficiently detailed or clear.

Still very interested in the FME and TSBK, possibly the 6 point brace as well if it can retain the rear seats in place. Would love to see physical pictures of it all installed with/without rear seats.
