In light of all of the sterling work that MAF has done with the SM 3200/4200 brake discs, I have also been squirrelling away behind the scenes and just wanted to update you with where we are to date.

We are currently quite advance with an engineering firm as to the remanufacture of the CambioCorsa clutch plate and cover on an exchange basis.

We will be offering a re lined and re sprung clutch plate in either organic or kevlar along with the clutch cover with upgraded stronger dual layer spring tangs.

Costs for the organic system will be significantly less than the OEM unit plus you have the added knowledge that the spring is substantially stronger.

The Kevlar system will be about the same as the OEM with the benefit of long life in the region of 100k miles.

This system will also be available for the F430

Ill update you when we know more but we are looking to trial a system in Q1 2015 offering this for sale in Q3 2015.

We are also turning our attentions to other parts such as QP and GT/S discs due to the success of our current SM offerings.

Brilliant Matt..........this forum is almost single handedly doing more to keep older masers on the road than Maserati themselves!

That's great news. What a brilliant forum. Are there any plans for clutch kits to fit 3200s or have I missed that one already?

Not been done yet Trev, but if the first clutch comes off and sufficient interest, then why not the 3200

Yes there are. We are currently working on this and should have some further information by next week.

Okay Conaero, I'm not disgruntled easily but............. I'm on the other thread here posting how I'm removing the clutch, thrust bearing, F1 Sensor, showing people how to do it and you did not mention this there. Additionally on the Maserati life forum I'm arguing with the owner of GTE engineering over his conduct over the phone because I was actually attempting to see at that time whether he could rebuild the PP with stronger fingers/tangs. The owner is very difficult to work with. GTE is basically the company out of Florida rebuilding Actuators as well. However he just put a rebuilt clutch into someone's Quattroporte and seems like the customer wasn't happy.

Anyway, I didn't think you were this far along or I would of gladly been a Guinea pig. Maybe we should also rename the thread I started "4200/GS clutch replacement" so people can find it. There's tons of hot spots in the PP, but the clutch friction discs itself wasn't damaged, it's glazed over, but wouldn't matter if it was rebuilt anyway. Additionally the PP might be able to be resurfaced so that those hot spots aren't there. It worked when I had the fly wheel resurfaced.

Here's some questions......... when we tried kevlar clutches on our cars in the U.S. with F1 systems it didn't work. They were really grabby, so either it was jerking the car and stalling it out, or when the PIS was set further back was constantly slipping, there wasn't really an in-between. Have you guys fixed this for Kevlar? The OEM organic material was the only material that has thus far worked.

Additionally, are you using the same thickness on the dual friction disc clutch plates? If the friction discs are thicker, also if you are resurfacing the plates, ie. Fly wheel, and pressure plate friction disc surface, it has to be within certain specs or it seems to throw the F1 system off. I believe that the Master Mechanic from ECS in Virginia stated you could resurface a Fly wheel twice and be within specs for our cars. I dug through the service manual and I couldn't find that data, so his assertion was based off of experience working on Mas. and F cars. My assumption is that when resurfacing Fly wheels they only remove about .010-015 each time that's what you'd have to work with to be within specs. Of course again that's just an assumption.

Well I actually have the brand new clutch pack arriving today in the mail according to tracking but had I realized you guys were this close.......well anyway. I was going to put a digital caliper on both friction discs to map there thickness for the ML forum. I can post it here as well if you'd like, ...and don't forget we like Mas. in the U.S. as well! Please keep me in the loop. What's the pricing for this as well. Maybe I can send mine over to have it rebuilt for later, or if there's a core charge and you need this one I will send it to you. Either way, feeling a bit left out now..:too_sad:....lol.

We are still a way off yet Craig, its just we actually have someone working on it now.

They have used Kevlar cluthes with great success and I pointed out that the reputation of the use of this material with the CC system has not been great and I was told its all to do with the set up.

I am no engineer, but when our experiments are over I will release the finding here but the guy doing the work has already rebuilt the F430 clutch and, in organic and kevlar and they are still running today successfully.

I personally would go or the organic material as we know you can achieve 50k miles out of it, its the spring tangs collapsing that mainly causes the premature failures.

Its a step in the right direction.

Okay.....I forgive you! Lol......I would be interested personally in the Kevlar as well as the PP. Additionally, let me know and I will put the information right along side the GTE guy on ML. I think they would be really interested as I am and I'm sure they would support the effort from a trusted source.

All sounds very interesting, looking forward to finding out the results of the trials. If we had clutches that lasted 100k miles, the cars would be even more popular ;)

Great work! I had my clutch changed less than 2000 kms ago so I hope i won't be needing a new one any time soon but will keep this in mind for the future.

Thanks!

Thats what we all should feel but these blessed spring tang failures seem to go any when from 8k miles and onwards.
