Is anyone (besides the dude that works at MCS) running MCS coilovers?

The rotors and the calipers are based around 'late model stock car' product catalogues from AP and StopTech. This is best because:
- designed to fit in 15inch wheel
- cheap, plentiful parts

The rotors are 11.75 x 1.25inch

[matthugie]

What diameter are those rotors? That looks like an amazing kit.

The brake cost.. Well they're a little OTT. They are my own creation and probably not economically viable for most E30 :)

Pics below show the current version of the rotor hats. I intend to make a few of these kits once I'm 100% satisfied with the design & spec. We're 99% there now.

Per below pics, the hats are 7075 T651 and the bobbins are 4340 cro mo. Hats will be anodised, bobbins will be tuftrided.

The hats allow for radial expansion of the rotors via elongated slots in the hat itelf. The bobbins lock into the hat to allow the rotor to be attached and tightened / removed with a single tool only. Hardware is 12,9 M8 SHCS. The approach taken with the bobbins is an adaption of Brembos "D type bobbin". The fronts are basically just a bit bigger than the Brembo size with a bigger lip to lock against. The rears work in reverse to allow rear float with a parking shoe (concentric to rotor, not the hat)

The rear hats are also fully floating with a unique approach to providing float and OEM hand brake functionality.

(rear rotors attached backwards, thanks for paying attention)

I'll do some better pics once I get the next version done (and polished & anodised)


thanks for the tip on the clamp, will check that.

Mind if I ask how much a set of those brakes cost? Are you using custom hats or something off the shelf? Your car is insane!

BTW be careful with how tight you clamp the canisters in the middle like that. The piston inside can sometimes get stuck or restricted when clamped too tight.

[burkey001]

Those brakes gotta have the clamping force of a bench vise. Jesus.

:) They are a little on the strong side. My own kit using Stoptech STR43 calipers and AP Racing J-hook rotors.



Once the PFC01 pads get some temp in them it is like hitting the pause button :) A good match in overkill to the MCS dampers.

The canisters are a bit of a bear to mount. Had to get a new strut bar made up with some mounting provisions. Glad I did.


Surprised I was supplied GC plates, I was expecting Vorshlag (better IMO).
Regardless, hands down better than my AST 4210. Back to back in two E30's, one MCS 2 way the other AST 2 way. MCS rides better, feels a little more composed and controlled.

MCS rides smoother (handles sharp edge bumps better, takes dips better, feels better on turn in) on 10 and 12KG/MM springs than AST does on 8 and 10KG/MM

We use nitrogen, there are a few companies that sell portable kits that include a tank, regulator, etc. in the 300-400 price range. Not saying that it's cheap, but I did see lots of these kits at NASA Nationals this past weekend. Regular air can be used if you're in a pinch, but we recommend using nitrogen for long term use.

But I will say that having adjustable can pressure is nice. It's kind of like adding spring rate when you're adding more pressure, so it's a helpful tool. Also if it's raining you don't need to change spring rates or make serious adjustments... just take out about 20lbs of pressure and maybe go one click softer on all four corners.

What type of gas do you add/subtract? Not a very common thing to have a nitrogen cylinder to add a few pounds when needed!

[burkey001]

I stuck with 4 lug, no regrets.

Dampers are amazing. Worth the price of admission.

[robgoesvroom]

did you decide to go with 5 lug E30 M3/E36 M3 setup or stick with E30 4lug? They look amazeballs

[burkey001]

Well they have arrived. Acolella did a good job assembling them :)



Those canisters are biiiig. Still assessing best place to put them and safest way to route the hoses.


All fits in quite well. Acolella, I do have some feedback too :)

[burkey001]

@acolella76 hopefully you see my custom 2 way order come across your desk / bench soon...

If you're building 2 way's with m3 strut tabs, they're my dampers! :)

[acolella76]

See, the thing is there are sales guys that'll try and hawk their parts all day long and then there's guys like Alex who would tell it to you straight. You have to consider no one is going to have a greater amount of experience as the one who made the part in the first place.

Consider it like talking to a car salesman about a certain car verses talking to the engineer who designed the car.

I appreciate the kind words :)

The MCSs are incredible. The most impressive thing to me is their ability to absorb and control bumps as if they weren't there, they are leaps and bounds above the TCKs in that regard. The tuning range is almost unbelievable.

Thanks, I'm always happy to hear what people think about our shocks.

Alright... 2 way remotes it is.

I figure this topic is now closed. Given these dampers have a value above the average cost of an E30 I assume the market is likely quite small :)

I really like my AST, so am looking forward to being wowed.

thank you

Great! Welcome to the "my shocks are worth more than my car" club! :D
