12-way Coilover's for the 928: ready!

[MarkRobinson]

Been working hard on this one:

Offering group-buy on the coilovers: $1255 for the full coilover replacement per my release below.








If you're interested, chime in on this forum & once I have 5 people confirmed/ready, I'll take payment & start the assembly process. Feel free to ask me questions or email me for more information.

I've approached PelicanParts with carrying this item, so there's a chance it'll be picked up by them in the future for immediate, in-stock kits from PelicanParts.com. Hard to tell yet if they'll carry it since 928 sales numbers are not too strong in-general. Thanks!

Wow!!!
Great work Mark. They're on the list. One of these days my $10000 car is gonna be worth $5000!

[Irish Legend]

Ps. I wish everybody put as much detail in their descriptions!

[Mrmerlin]

the new shock kit looks great,
I would add that if the pistons are exposed then when the tire gets small rocks on it they will eventually be hitting the pistons and thus the pistons will begin to leak,
similar to sandblasting the piston rod,
a dust boot would be a valuable addition to the front assembly.

[MPDano]

Wow, those a very good looking!

[Mrmerlin]

I have an Ohlins shock on my BMW R1150 GS front suspension and its piston is exposed to the front , i took a piece of inner tube and zip tied it to the outside of the front of the spring, this effectively blocks the stones from blasting the piston,
My friend also had an Ohlins on their BMW without this mod and the shock was leaking after 3K miles of use

looks very nice.... wish I could afford a set....

I wonder if I put a link on rennlist if anybody will go bonkers? About to find out.

Wow, that's timely!

Thanks Danglerb for posting this on RL, since I'm not watching Pelican closely - but I'm currently looking for a coilover setup for my project car and this looks exactly like something I'd buy.

A couple of questions:
- Anyone ran this on their 928 already for any significant time? How's reliability?
- Are shocks in S/T kit double adjustable too - or, I guess, the whole price difference between S/T and T is there because of this feature?
- Is it possible to maybe get some "mixed" kit? Like the T kit with S/T spring rates, for example?
- Mark, are you willing to ship overseas yourself of prefer to use US proxy shipper?

Many thanks.

Great, now something else to spend money on. I already need new tires, AND an alignment.

I figure if QA1 had similar past-experiences they would have already done that, but I'll mention it to them again; thanks.

Hi Alex,
I've ran the kit since February and Don in Texas has also had a full set since March to help me ensure all little issues are taken care of including suggested settings, spring rates, clearances, etc. Don says it certainly moderized the feel of his 928.

The S/T has the same single-adjustable shocks: correct, double are quite a bit more expensive.

Absolutely spring rates can be custom-ordered, no problem: QA1 has a lot to offer: no charge for custom spring rates either as they're all priced the same.

International shipping: absolutely!

[genikz]

I'm in for a set, if I can order the single-adjustable dampers with custom spring rates. Should I email you the specifics? Or can we order online?

[Ducman82]

any pictures on how they mount on the rear lower arm?

[MarkRobinson]

Chris: yes on the custom spring rates; let's wait until I've met at least 5 orders ready to go (my minimum to offer these discounts) before I gather your requirements.

Ducman82, the rear mounts are a proprietary design & trying not to let the cat out of the bag until people have them on their car. I'm also having my Engineers study recreating the mounts in aluminum for a cleaner application (my opinion) & slight weight savings (maybe 1-2lb). In a nutshell, it's a twin-tab, cantilevered design off the rear suspension pin, where the ensemble is keyed to the rear control arm. Geometry remains as it was designed for the most part, except the lower shock mount is on a bearing to keep the rear shock floating & without any preload as the factory system could be loaded since the lower angle of the shock mount was fixed. Shock was selected for this application where the piston stop was centered in the housing with the car at near-stock ride height, giving you plenty of suspension range both above and below the stop.

Thanks! Mark.

[genikz]

Sounds good, Mark. I'm in no immediate rush.

Please email me at genikz *at* yahoo . com when you're ready.

First I'd like to say awesome work putting this together.
Not quite clear on the configuration of the rear lower shock mount. Just to reiterate, from an RL discussion about tie down plates. The pin rotates relative to the lower control arm, so the lower bushing addaptors need to be designed to allow this. The pin is rotationally tied to the suspension upright.

[MarkRobinson]

Correct. My lower shock mount is secured to the lower control arm assembly, where the lower suspension pin is free to rotate as suspension moves though the mount & mounting tabs for the shock only move with the control arm assembly. The lower shock mount is on a bearing for infinite suspension geometry change, and the upper nitrile mount allows shock movement as well, although not as much.

[76FJ55]

Excellent !

[MarkRobinson]

BTW: I've been asked by a few: yes, you can pay $1255/2 ($627.50) for just the fronts or just the rears if you wish. Fronts alone make a huge difference in handling.

Happy Friday!

Note: above image shows a development-only upper mount: rears are wider, cover the thru-hole into the engine bay.
