Default Re: CMP Auto Engineering subframe kit

Will there be a groupbuy for this newest product, the full 4 point (well, actually 6 pt) harness/brace?

The earlier groupbuy was for just the flat rear bar right?

Cheers

Might be interested in group buy option as well.

This new design looks fantastic. Been holding out for a complete solution like this, this looks like it fits the bill combines the best of the Vince + Mason solutions all-in-one.

Count me in if there's a group buy whenever this product is ready.

Looking forward to this set please let us know how it goes
Thanks Cagan. I certainly will.

I'm just waiting on my laser cutter now. If I can get the parts in time, I'll have some install shots to share around the 29th. Otherwise I'll have to push it back further.

Hi Tbone, You are correct. The Group buy was for just the topside beam kit as that is all I had on offer at the time.

Sure guys. If there's sufficient interest for a group buy I'd love the opportunity to offer that to the community. I've been getting interest over Facebook as well so I'm sure there's bound to be enough to achieve a very reasonable discount.

I'll let you know when things are at that stage where I can do that and I'll get it happening.

By that time I'll likely also have on offer aluminium subframe raising bushes of my own design that I could also include in the group buy for those interested in upgrading?
For those interested, my machinist recently arrived back from holiday and is machining the first prototype set this week. I plan to install them along with the additional chassis support during the 26th-29th long weekend.

Default Re: CMP Auto Engineering subframe kit

Morning guys,

I have some good news and some bad news.

Good news is I can finally provide the pricing for the front mount extensions. It's looking like I'll be able to provide them at $280 AUD (~$220 USD) + shipping. This is before the coming group buy discount.

The bad news is that my laser cutter has such a large back log from the Christmas break that I wont be receiving the first batch till Monday the 5th of Feb. I'm pushing to have it on Friday the 2nd so I can install it over that weekend however, that's only if I'm lucky.

So this has pushed my plans back about 2 weeks and the release of the product to about Monday the 19th. The brace will likely be available in March and I'll be starting the group buy during this time.

I apologise in advance if that lead time is an inconvenience to anyone.

EDIT: Forgot to mention, at this point in time I do not plan to supply extended fasteners for the front mount extension kit like I do in the rears. This is because the drive line forces are jacking into the chassis not pulling down meaning, the stress is transferred through the contact between the top of the front mount and the plate at the base of the tubes. The fastener tension and top nut clamping force are in the opposing direction to that which would resist the drive line forces.
Instead, the base of tube plate has been designed to tie into both the factory mig weld locations for a direct link and also include a centred hole in order to secure the tube/plate during the welding process. With the hole present, anyone with extended front fasteners can reuse them when looking to upgrade to this kit.

just wanted to mention it to avoid confusion in future.

I was looking at the horizontal plate that sits on top of the mount. I've attached a few sketches.

That's simply not true. Force and moment transfer into and out of the shock bolt location is conveyed through the thin cross section of the flat plate. Welding or bolting the vertical plate to the shock tower results in increased rigidity because the joint rotation is not centered on the flat plate.

The Mason has a more rigid joint at the shock tower mount because of the way the additional bolts in the vertical face of the shock tower increase the transfer of moment to the joint. It is by inspection more effective at transferring more moment at that joint than a slightly thicker flat plate.
