I think suspension has become the weakest link for MPS6 in the track. If you are going to the track, upgraded suspension is a must for this car if you want to pull out the full potential out of it. My dilemma now is should I still invest new part or new car?
I think the fundamental issue is that the MPS6 was never designed as a track car. It is a "light luxury GT", a genuine 4 door high speed in comfort touring car. Rather than thinking of the suspension as being a somehow deficient aspect, consider it as being entirely suited (within price limits) to the job it was designed to do. If you want to take an MPS6 around a track the first thing you'd do is strip it out to reduce weight, rather than stress (initially) about suspension issues. I think it's a it of a shame to flog an MPS around a track actually, unless it is specifically rebuilt for the task, in which case it is largely written off as a road car, which would be another pity anyway. That's just my opinion and I know others will feel differently.
I think you spot on Doug.. I fully agree with that..
The weight does kill its cornering ability, it's sad to see mx5 manage to outpace every corner compare to mps6. But of cause, straight line is another story.
But I think may be bolt on a TEIN coilover with electronic dampening adjustment will be a good compromise for both good cornering speed while maintain luxury GT enjoyment. What do you guys think?
i would say do the little things to see what happen, things like:
space saver, tools, car mats, rear space saver cover - take these all out;
front strut tower bar - gives you a bit more understeer;
upper rear body strut bar - i have one of these, installed at the same time as front strut tower;
battery - change to something dry cell/light weight;
front bushes - superpro bushes, camber, caster and uppper and lower control arm upgrade to urethane - i have these done in my car;
Semi slick tyres - not sure about the MA-Z1's they would b good for road use, but may not be good for track;
Brake rotor, brake line and fluid upgrade - slotted rotors perhaps, change to braided, and a good quality fluid.
Noticed in your sig you have kings on bilsteins - b8 i am assuming? These are probably a bit too soft to track, maybe move to Koni where you can adjust the damper settings, or coilovers with the manual damper adjustments?
Tiens with the EDFC would be really expensive, but if you have the cash, then go for it.
I don't believe you can match corner speed with an MX-5, the thing is designed for turns
Not sure if the Bilstein shocks I got is B8 as I got it from US. Yes, it does feel too soft on the track. Any idea how much would TEIN with EDFC set me back? My research shows me 2000+. Any one here had tried TEIN in their MPS?
If you do have the B8's then the Tein will be a BIG step backwards in terms of performance...Quote:

It's true that the 6MPS has a design flaw in that the front camber is non-adjustable, but that's the only criticism I have of the suspension, and its fixable. The double wishbones up front are superior to struts and I've never been beaten through a corner by any car that was not heavily modified. In fact I find the capability of the 6MPS chassis to be at a level where the only place you could use its full potential is at the track. This is the primary reason I have held onto the car despite its age.
Mate I think there's a lot more driving enjoyment in your car waiting to be discovered.
Is this one B8?Quote:

I doubt the Tein will be a step backwards compare to this shocks... as it's only less than $500. And it does feel too soft on the track.

You are right, once I bring it on the track, there are a lot more excitement to be discovered... :)Quote:

RPM store part numbers are the B8's.
You tracking with the DCS on or off??
DSC on... but that should not affect the body roll problem.Quote:

Compared to B8's, no debate about it, the Tein would be a a MASSIVE step backwards in terms of performance...
Nup, they're the B6.Quote:

I stand corrected. yes these are B6sQuote:

seems like this upgrade is not really worth much, I think I will keep the Bilstein shocks and enjoy as much zoom zoom as I can on the track. Thanks guys..

Kmac strut tops... Superpro bushes, take your pick. Searching helps too.

Will be as difficult as finding struts in a 6 MPS. They as @kmh001 (Mal) said, they have double wishbone, not struts
I found the struts! They where behind the couch. :PQuote:

Kmac are really easy to deal with too.
Replacing the bushes with adjustable ones works too, in fact I am doing both the bushes and the tops when I get around to putting in the eibach springs and B8s I've had sitting here.
Edit: Sorry. Never mind...... double wishbone, strut top won't do anything... sorry hadn't had my coffe when I posted. Anyway K-mac make a kit as well as the superpro option.

ok, so the only option is to go with the bushes...
