Right.. I have been away from this forum for some time now and think an update is needed.


I changed the BC's for the Megan racing.


These kits are apart from different anodizing colors almost identical in appearance and sizes

The Megan kit is only sold with pillowball topmounts in front, so in that aspect differs from the BC with rubber topmounts that I had.

When mounting, it turned out the brackets for the front brakeline mountings didn't fit, the opening in the brackets was too small for the lines, I had to make a small change.

Then it turned out that the pillowball topmounts with camber adjustment didn't fit through the front schocktower openings: the camberplate mounting bolts were just 1-2 mil too wide apart and catched on the edge of the bodywork hole, thus preventing the front topmount to fully seat on the underside of metal of the shocktower, I put inbetween 3 shims per shock to fill,out the gap. Crappy way, but otherwose I would have had to grind into the strut tower holes to make those a little bigger and wasn't prepared to do that damaging the car.

Again the same as with the BC , the rear stance even on highest strut setting is too low, 1 3/4-2 inch lower then OE stance, nothing can be done about that.

Then driving experiences..
Roadholding and cornering is OK, clearly stiffer and much less leaning in corners, but...
On flat roads it is OK, but on bad roads the kit rattles like the parts are not tightened, like all suspension parts are worn out, or loose.... really terrible.
Also when parking with full lock steering and turning back, you hear the front springs making cloncking sounds.

Conclusion..
These kits are JUNK

Never had crappy parts like these 2 kits on any other car in over 40Y of car ownership, having had several other good make coilover kits on other cars.

So the Megan kit is also coming off again.
I am amazed this junk is beeing sold.

Am seriously considering either putting back the OE struts and selling the car or having a custom kit made by a specialised suspension workshop making kits for rally/track cars based on either Bilstein or Öhlin shocks, but pricelevel of that is a seriously high, have to consider if this will be worth it to me.

So only thing I can say on the BC and Megan kits for the MDX G3 is:
DON'T do it!!!!! If you have ever experienced good sport suspension, these 2 in comparison are Junk

Yep, I don't like clearly lowered cars either (those where part of the tires are in the wheelwells).
This is why I set the coilovers as high as possible, but that still meant a 1 1/4" drop (I think with this kit you could drop the car 3-4 inches if you wanted to, not my thing..).

However, as the wheelwell gaps above the tyres were quite big to start with, this means that even in the 1 1/4 " lowered stance a gap between wheelwells and tires remains, not giving the obvious lowered look.

Stance as is now, looks good and acceptable for me and ofcourse the lowering means lower gravity point, thus better cornering just as result of the lowering..
And the sportier characteristics of the BC shocks and springs adding a lot more cornering sharpness to this.


A few fast not so good pics
Hight like this is nice I think, but I wouldn't want it lowered more..

Pic 1 is OE hight
Pic2-4 is with BC
Pic 5 is comparison BC-OE front strut
What rims are those?

Yeah I have the Megan racing’s on mine and it’s rides smooth and all but when you hit bumps it sounds like ****! And on the tower part. Yes feels like you gotta cut out the top frame

Sorry for the late reply, been busy, the rims are OE Infinity FX/QX in 21 x 9,5 ET50
Center hole too big, so had bushes machined to get perfect centered fit and had to find special wheelnuts as the Infiniti and Acura's are wrong sizes to combine wheel-car ;-)

After long thinking about what to do, either:
  • get rid of the MDX and turn to a BMW Alpina/ Porsche SUV but having to dish out a lot of additional cash to do so
  • keep the MDX and have a real good suspension custom made at still high cost, but lot less then buying another car..
And as I (somewhat surprisingly) do like the MDX..I decided to go for a custom suspension upgrade..

So since last weekend the MDX is at the workshop of a very reputable suspension specialist who makes custom suspension for race/rallye/ high end custom cars.
They will make a custom setup based on Öhlins shocks with specially made springs, all custom made to size to fit.
It will be a upside-down setup with both adjustable ride hight and adjustable combined bump/rebound damper settings, they will make full setup adjustment, but I will be able to make adjustments if I want to play with it a bit.

They measured/ investigated and tested the Megan (and as such BC as that is 99% the same) setup and were not surprised that it doesn't function.
At first they were somewhat surprised how it is possible to manufacture such a relatively good looking kit for such a low price, but after taking things apart they found out Megan/ BC produce something like a lego set, using more or less the same basic shocks and springs with all different mounting parts to fit to loads of different cars ....thus making really cheap production possible.

It turns out that the front Megan shocks have about 70mm free travel which isn't bad.....but when the wheels are on the ground, so load is on them... only 17mm ingoing suspension travel was left on the fronts to take up bumps, after that, they hit the bumpstops.
So now it is clear why the front suspension rattles like crazy and car is jumping all over the place when on bad road: it is hitting the bumpstops all the time

Due to the design time, custom production and lasercutting + corrosion protection of parts, building all together, testing and setup, it will be about 3 weeks to get things done.

Very curious what the difference will be..

What in the **** are you doing that the stock setup is insufficient? Just go with the body roll and take advantage of the Shawd

Part of the fun of ownership is to customize it as you please. Glad someone is experimenting with this vehicle. Looking forward to the results.

Suspension is one area that differences can be felt pretty immediately, but bad geometry can really bring up ugly results quickly. So it's a gratifying experience for folks who like to really get into the driving dynamics of their vehicles. I went down that pit years ago lol

Here in Europe we have mostly somewhat tighter roads and as such sharper narrower corners, also our general driving style differs a bit from the US.

In that aspect I have to admit that I am also a bit different from (above) the norm as I also race in my country's Miata cup and like a bit of sharp driving style on the road too.

Even though I do not speed too much on public roads, I do tend to take corners a bit more agressive and have above average wishes concerning roadholding as I know what is possible with a good setup.

I have had loads of nice sporty cars, in the SUV segment having owned Porsche Cayenne Turbo, Mercedes ML500 and ML63amg.

Next to the MDX I am lucky to also own a few very nice hobby sports cars (Mercedes CLK550 convertible with Bilstein coilover kit, tuned Toyota MR2 Turbo with KW V3 coilovers and NSX-T supercharged with new type-s suspension)

In this aspect I am surprising myself by the fact that I really like the MDX as overall package daily driver..
I do miss the high HP of the P and MB's a bit, but the MDX's much lower maintenance cost and reliability makes up for that and luxury wise it is more than up to par with these.
The roadholding however is a constant irritation and if this were remidied, for me the MDX will be close to a perfect daily driver for me

Correct, I always drive every car that I ever buy for a short time and then go to my alignment specialist who has worked on every car that I have ever ownend for more then 35 years to have it's alignment customized to my personal preferences to get the roadholding and under/oversteer and steering responsiveness that I like.
This guy exactly knows what to change when he hears what I do and don't like about the driving characteristics of a car.
This can make a big difference.

MDX is not the vehicle for aftermarket customization.

I beg to differ..
In it's class, it is a very nice car, but performance-wize with the right mods it could be better.

So I wonder.. what in your opinion makes a vehicle a good subject for customization?

In my opinion, a vehicle that in it's class is good, but with some mods could be better, is.. ;)

In my opinion a car that is a good subject for customization is one that has aftermarket parts available.
