    K-MAC suspension gear - is it any good?

    Long story short, I need more caster. So i'm looking at getting some camber/caster plates. Theres only two companies that offer them for my car so I have a choice between K-MAC or Ground Control in the states.

    Looking at either these:

    http://www.k-mac.com/pages/newprods/Stage_3.htm

    or these:

    http://www.ground-control-store.com/.../II=146/CA=191

    After doing a fair bit of research I have seen a lot of mixed reviews about K-MAC gear. But considering they are the same price (roughly) as the Ground Control ones, i'm not sure which ones to get. Any first hand experiences out there?

    Go down to K-Mac's workshop in rockdale.... lol I've never laughed so much... the place is a shithole with all the staff looking like they're illegal immigrants..... Kevin (the owner) is also a huge dickhead.
    Know a few guys who have bought swaybars etc from them.. the hardware they send to mount it to your car is stuff used on farm gates etc (the kinda thing u'd get down at bunnings) and in some cases it was the wrong bits.....

    The "stage 3" strut tops can be OK but you will need to pull them apart and locktight them as he wonderful "design" unwinds the spherical bearing holder when you do up the shock nut. Every other k-mac part I had bought hasn't fitted the car...

    I used Kmac springs for ages, they were excellent in the end but it took 3 tries to get it right (i wasnt going to accept springs that werent exactly what i asked for).

    If ground control is the same price go with them, quality gear.

    there is no noltec or whiteline anymore really. Red ranger purchased the lot and its all under nolathane/redranger group now. Whiteline werent even doing their own bars and stuff when it all happened, huge delays on ordering anything and a lot of the old stock they used to make for older cars arent being made anymore (same goes for ordering bushes, a lot of the noltec catalog isnt being made).

    Selbys used to make a lot of the bars, but their website is virtually non existant, so ive got no idea what they are doing now.

    Red Ranger bought them out like 4-5 years ago now. I thought Fulcrum bought the Selby's brand and are now making the bars now. Pretty sure the guy that use to run Selby then setup Singature Swaybars and operates out of a joint in Taren Point.

    I bought ground control stuff - camber/castor plates, spring perches and eibach springs to convert my front struts to all adjustable for my 1600 and it's pretty decent quality. Trevor there was goos to deal with.

    I had bad experiences with Noltec camber tops. Didn't fit properly (had to be adjusted by my mechanic) and a couple of years and limited kms (~5000) the bushes collapsed.

    I have noltecs in the front of mine and they are similar in design to the K-mac.

    I would get the U.S ones that you have the link for. The only reason being that the camber and castor adjustment are not together.
    i.e you can adjust camber and not disrupt the cator and vise versa. On my ones you undo the adjusting nuts and you adjust everything at once. Big PAIN!!

    At the end of the day ease of use!!

    Hahaha so true... i dont even think the site has changed since then Best of all their tuning hints section is full of errors... like this gem:

    Oversteer: (Rear breaking traction) As with understeer, both rigid and soft suspensions can cause oversteer . With "roll oversteer" the car leans heavily, hitting the bump rubbers and causing a skipping action of the rear end, often resulting in an inversion of the car. "Rigid oversteer" is brought about by a tight suspension set-up which does transfer sufficient weight to the wheel doing all the work.


    Understeer: (Front breaking traction) We emphasis that understeer can be caused by both too hard or too soft suspension. The hard suspension will have a tendency to "jump" on unsmooth surfaces, thus lessening contact between tires and the road. With soft suspension the tendency to accentuate centrifugal forces by excessive body roll causes the type of understeer that most of us have experienced at one time or another.

    if you run spring rates of more than about 300lb, they should have sold you the solid ones.

    Noltec are fuckin useless... no wonder they went out of business...

    My strut tops haven't seen a proper load, ie rolling shell and they crumbled apart. I've since stripped the blue shit out and had them poured with new poly.
    Front CAB's same deal, they literally have fallen apart.
    E30 rear subframe mounts are the wrong design and fell apart. I'm rancid about that now as I have to reset the diff mount/rear end to accomodate as it was set up using Noltec subframe mounts. Everything sat ~10mm lower then it should have.

    same happened to me with Noltec, put control arm bushes in, crumbled apart in less than 6mths with minimal use. Utter shit.
    A guy in an RX-2 had a suspension setup literally fall apart on the track with noltec products in the front end.

    Understeer is when you hit the wall with the front of the car and oversteer is when you hit the wall with the rear of the car. Horsepower is how fast you hit the wall, torque is how far you take the wall with you. Even I know that....

    I use their springs, to me they looked like shit as in rattle can paint on them but they worked exactly as expected and the poundage was right first time, they even labeled the drivers side with DS on a old school paper tag, i told them what i want and i got what i wanted so I'm not complaining, my next set of springs will be Kmac

    K-Mac quality is at best average and getting support can be hit or miss - just my experience.

    I tried to get Kmac strut tops for my Triumph, so 15-20 years ago now, and even then they, Kmac, were shit. The suspension bloke I was dealing reckoned they will list everything for everycar ever made but really only could do about half of what they said they could, and only if that bit will fit something else.

    We have only just been made aware of this 2011 input. Now 2015 so obviously car enthusiasts see it for what it is, those not with positive, constructive input, but delight instead in negativity!

    CONSTANTLY DESIGNING, CREATING, INVENTING – along the way mistakes (including in 2008 orange powder coat finish) are made. To quote Ferdinand Porsche “if one does not fail at times then you have not challenged yourself”.

    The reality at K-MAC is that 2011 was the year that TV show “Wheels in Motion” voted K-MAC “Best Performance Products” at Americas leading Performance Racing Industry (PRI) Show in Orlando Florida (over 1000 Exhibitors) – and featured K-MAC on their Time Warner America/Canada weekly program with over 8 million viewers.

    Re the K-MAC factory in Banksia Sydney – yes it is full on when it comes to activity both staff and production (unlike opposition imports where their only effort is to inspect product appearance)!

    As it has been conceded, K-MAC is far ahead when it comes to product designs (K-MAC as used in all out competition by Peter Brock at Bathurst in 1977 along with the first 6 placegetters).

    Do point out that unlike the companies mentioned, Noltec and Whiteline – we do not source our products in Asia. Instead we proudly manufacture (and employ all Australians) here in Australia!

    Re the comparison of these two companies’ products to K-MAC – we also point out that they have both paid royalties and commissions on sales for the entitlement to reproduce these patented design K-MAC products.

    BRIEF CHECKLIST/BACKGROUND RE K-MAC “WORLD FIRST” ACHIEVEMENTS:
    • The original aftermarket manufacturer of front and rear anti sway bars (with World’s largest range 1950 Ford Custom to 2015 makes/models)
    • The longest established/most experienced and World’s largest range - Front and Rear Camber, Caster, Toe adjuster kits (Audi to Volvo)
    • The original aftermarket manufacturer of variable rate coil springs
    • The original automotive coil spring manufacturer to use “ultimate” resistance heating – heating from the core outwards

    ALONG WITH OVER 20 PATENTS AND PATENTS PENDING ON INNOVATIVE DESIGN BREAKTHROUGHS FOR THE “WHEEL ALIGNMENT INDUSTRY”....

    SOME OF THE ACTUAL K-MAC INVENTIONS INCLUDE:
    BALLJOINTS – Sliding adjustable (now industry standard World-wide)
    BUSHINGS – Eliminating need of last 40 or more years of labour intensive disassembly. Now on car precise single wrench adjustment
    STRUTS – 2 bolt flange – No undersize crank bolts, nonslip and with three times the adjustment range of crank bolts
    Top mounts – aperature design providing biggest/quickest adjustment system
    Top mounts – adjustment even though no OEM mount studs
    Top mounts – adjustment where no coil spring to tower clearance
    2005 up Mustang – adjustment without the need for special tools or disassembly
    2010 up Camaro – adjustment without strut tower mods

    With ultimate testing proving on the racetrack. In all out 10/10th heavy V8’s competition racing. Situations where “race safety” scrutineers through comparison/evaluation rule K-MAC and only K-MAC adjuster kits are allowed to be used!

    SO YES DESIGNING, CREATING, INVENTING NEW PRODUCTS – DOES CREATE CONTROVERSY. But for all of us at K-MAC it’s all about advancement/setting new industry standards and proudly not importing but having “in-house” manufacture and therefore total control over quality. Also allowing rapid/constant design updates.

    A WHOLE LOT BETTER THAN THE APPROACH (AM SURE ALL AGREE) OF MERELY SOURCING IMPORTS, RELABELLING AND SITTING ON THE FENCE WTHOUT CONTROVERSY – DOING NOTHING FLAWLESSLY!

    So check out our website... re very latest versions 2015/2016 (MK4) “replacement top strut mounts” for AUDI to VOLVO and our “adjustable bushing kits”.

    K-MAC – always 1st with the 3 essential product requirements;
    “strength”, “durability” and “adjustment range”

    INSIST ON GENUINE K-MAC – DONT BE SOLD SUBSTITUTES

    Well, I now feel Coached!
    Soft roaders represent an excellent compromise between the needs of the hardcore 4x4 user and the convenience of a city hatchback. Its clear to see why they have become so popular in todays society.

    THANK YOU SO MUCH to K-MAC for bringing this thread to our attention.

    Looking back I was UNAWARE of the injustices being brought against K-MAC a little over 4 YEARS AGO!

    Thanks to K-MAC, I am going to place an order with GROUND CONTROL as I didn't know they made SWAY BAR END LINKS for my CAR.

    K-MAC is my NUMBER ONE source for links to SUSPENSION websites. THANKS GUYS.
