My race series that I compete in requires 2-way dampeners for street class so that is what i would be looking at. This would be upgrading from DG/Koni coilovers.

An off the shelf 2-way is about $5000. what would be the up charge to make the custom set for an Eclipse?

I'm guessing that would fall under "2-Way Custom" which seem to average ~$6500.

I understood 2-way custom as custom valving not a custom application where a body would need to be modified for mounting.

Anyways, its out of my price range and doubt i'd tell a big difference at my skill level with the already competent Koni's i have. I'd also look at Penske at this point as there reputation is impeccable. MCS is unheard of on this side of the world.

Hello everyone. I think there is some confusion the suspension is MCA not MCS.

These are their normal line of three way adjustable. Here is their website: Gold Series | MCA Suspension

According to Murray the pricing is $1150 each with those options.

Here is some more damper porn for you though:

Oooo... shiny... Lol. On a more serious note, those look like some pretty nice units. What turns them that color? Just a zinc coating for corrosion resistance? And where exactly did you plan on mounting or running your remote canisters to? I assume mounting the rears inside the chassis, but I'd like to hear from the man himself.

Those are actually two questions I dont know the answer to. I am down under in about a week to test the car so I will get back to you on what coating he used and where we put the canisters.

I'm going to guess electroless nickel

With that much of a gold hue? The electroless nickel I've seen applied to firearms is generally much more silver in appearance. I would say a nitride finish maybe, but it makes more sense to put that on the actual shock rod for hardness purposes rather than corrosion resistance. Guess we'll find out next week when Andrew reports in next.

Willing to share what the new spring rates will be?

I'm hoping it is Titanium Nitride.... dont know the spring rates yet. Gotta get out and test the thing and sort that out.

I promise it is not titanium nitride. I'm not sure if you're joking though.

I might have started the MCA/MCS confusion....

Nice to see the options that are available now. Good luck with testing next week!

HAHA I did add to it.

I know what he runs but just went and did a quick search and post based off what I read.

"bling bling"...

I am in the Narita airport now on the way to Australia for our test! The car drove around the block, and is going on the dyno soon. The guys got it back together, weather has not cooperated so far.

Best of luck !

^ I'm with him. Best of luck Andrew. Let us know how it all turns out. Any chance you can give us any details on the engine build?

Thanks guys,

The workshop knows the exact parts list and I know the basics. Right now we are totally focused on chasing reliability, so power is the opposite of what we need at the moment. The head is the nice head though and the bottom end is a bit of a throw together to make it to WTAC last year. It is still the OEM crankshaft, 100mm stroke, 2.4 6 bolt block 156mm rod, 22mm pin. Head is a GT auto garage CnC ported piece. Big custom grind camshafts, dual valve springs, yada yada. We are not really using the engine to potential at all. If this car was going for drag racing I think that head and turbo would be 750whp or something crazy. Last year at WTAC it was tuned on no timing at all, 22-24psi boost on a 6262 (which seems a little laggy for what we are doing) it was almost 580whp like that.

For this test we are not using a pro driver (the engine tuner David Lenthall is driving it) and it will be a little wet out there with showers off and on. So we have the tiny WG spring in it and boost control turned off, set to be right around 400whp. At this boost the turbo is way out of the sweet spot but thats not what we are out to test.

Cool, thanks for the insight. May I ask why the 6-Bolt 2.4 vs the 7-Bolt? Just what you already had? What kind of compression are you running? I would assume ~10:1 since you guy get to run on race gas all the time, but I could be wrong. And have you looked into the BW EFR series turbos? That's what Nemo has been running, as well as several others it the WTAC field. Or are you just wanting to get the chassis sorted for now now and deal with engine/power once everything else is squared away?

Other turbos have been discussed but for now, the outdated PTE is still a great bang for the buck and significantly cheaper than a ball bearing Garrett or FP or BW EFR or PTE Gen 2 stuff. It was mainly a cost vs. reward vs. replacement duration. The 6262 is 1/2 the cost of the other turbos.

Chassis and driveline sorting is the biggest thing currently. The aero and suspension changes alone will need some track time to dial in and crunch the data.

Plans are in the works for a different rotating assembly and an updated design gearset but what we have right now does the job for what the testing needs. The motor is plenty capable of power in the current setup, the gearset was the biggest issue last time.

Gears? Who needs gear? Moar Power!

Kidding aside I hope you guys can get the gear box worked out. It seems like one of the really big problems. I sure hope the only answer is a full blown race unit. Those thing are so expensive.

What types of issues were you running into with the gearset? I know the torque from the 2.4 doesn't play nice with our stock gears (4th is usually the culprit, I believe), so does that weigh in the most on the issues? Or possibly the wider tires? Or are you just looking to optimize it for the track?

I'm curious as I'd eventually like to go with a 2.4 built for road racing and am wondering if I could run into some of the same issues (not running the crazy aero or massive tires). I also enjoy learning what problems the people who are really pushing the envelope run into

Andrew out testing the new MCA suspension at the track now!

Good Luck Andrew!!

Love this build. Keep it up!

How did it go? I put the hankook semis on it for the guys. Dave was saying he was going to have a steer.
