I went and looked thru the parts bin at my friends shop by crossref'n the Centerforce catalog I found these disc might work on the 944 non-turbo

1983-1992 Ford Ranger 4-Cyl. 2.0L & 2.3L
1993-1997 Ford Ranger 4-Cyl. 2.3L
1983-1992 Ford Ranger 6-Cyl. 2.9L
Mitsubishi Starion 2.6L Non-Turbo & Turbo - No Intercooler (also Dodge Conquest)

They are all 225mm with the 1"-23 Spline. The Mitsubishi might hit the flywheel bolts but I think the ford might work. I ordered a ford disc to check and will pull my flywheel off. I found one of my old friends that can rebuild the stock clutch plate with a new sprung center. The Ford disc cost $30 and the mitsu is $38

Some of the Ford Discs have the springs center with the disc (early 4 cyl) and some are higher to clear the flywheel bolts (V6 one). The mitsu has the springs on center so it might hit the flywheel bolts. I need to check the late 4 cyl. one becasue it has a different part number. I will confirm this by taking apart my clutch this weekend.

I was about to do a clutch job... I may as well go buy a mopar disk and give it a try.

Thanks for the link LT1.

No prob.

Autozone has the disc for 16 bucks. Thats a good price for trying out and sizing up. As far as running a 16 dollar clutch disc....who knows?!?!

Funny, first its the discs are too expensive, then its the discs are too cheap. It looks as if it will come down to, will the 10" disc fit in a 9.45" disc's spot. If it does.....you guys are in luck!

FRporscheman

Oh yeah.... I was reading all those numbers like 10.5", 11", 12"... I forgot you hybrid guys have bigger (flywheels) than us 4-cyl guys.

I wanted to try this with an S2 flywheel which is the same size as all the naturally aspirated cars: 225mm.

Luckily I have a 951 flywheel and an S2 flywheel in my garage. I just went out there and measured. It looks like the largest clutch disk that will fit in either setup is only a 1.5mm larger than stock. Maybe 2mm but that would probably rub. On the S2, the clutch sits in a recession in the flywheel, so I'm sure a machine shop could machine away the wall and open it up, but still, maybe only 1mm. On the 951 FW, the clutch sits in a recession in the PP, and most machine shops can't do anything to PPs.

So unless a mopar clutch exists in 8.93" or less, the NA guys are out of luck. For the turbo guys, 9.51" is the max. If there is a 9.5" mopar disk then we're golden. Shoot, for $16 clutck disks, would it be worth it to switch the flywheel, PP, release bearing, bellhousing to 951 parts?

Well thats no problem. 1988-1992 Mazda MX6's share the same clutch disc as well. They cost about 30-50 bucks depending if you go to autozone or partsamerica.

If Mazda aint rubbin you right, go with Ford. Ford probes 1990-1992 share the same disc as well. 1993-1997 ford rangers do too. They range from 225mm to 241mm. Take your pick. Dodge trucks have the same disc too as does the Mercury Capri V6.

You know what you can do? You can go to summitracing.com and type in the search bar what you want and itll tell you what car shares the part. I type in "9.5 in. clutch disc 23 spline" and it shows all the cars that have that size disc. Then I just narrow it down by shaft size of 1". Then I take the car year I choose and search autozone or partsamerica or rockauto whatever to find the cheapest disc. Thats it. Or you could google the hell out of that phrase but that take a while. hahaha.

FRporscheman

Wow, that's fantastic. I was all bummed out; I just went to a local domestic parts shop and asked them to find me a mopar disk, and the guy there said he's never heard of anything smaller than 10.5", so I thought it was all over!

I'm going to write up a list and run down to autozone (2 blocks away). Ill take my old disc and flywheel with me.

Speedtek, I totally missed your post. I will look specifically at ford discs and see if something works.

We could be making history, people! Never again will the poor 944 owner have to be price gouged. Unless he/she buys something other than a clutch disc.

FRporscheman

I bought a 1991 ford ranger v6 3.0 clutch, and the damn thing slips right on the driveshaft like it belongs there. It is exactly the same diameter as the S2 disc. But the hub hits the flywheel bolts. While I was there, I ordered a 1984 mazda 626 disc and a 1986 mitsubishi starion disc. Luckily I can return all this stuff. I'll try those other discs when they get in.

I'm about to head out and see what I can find as far as 240mm discs. The S2 flywheel has the friction surface at almost the same level as the inner section for the bolts. The 951 flywheel inner section is set back a good amount, and I think the 944 NA is the same as the 951. If I can find a good disc for the 951 I'll let y'all know but so far we're 0/1 for the 16-valvers.

I just never stopped to think about how car companies' driveshaft splines could/would be the same, I thought they were proprietary.

Save a nickel and maybe spend a dollar 3 months later. I agree though that the 944/951 disc is way overpriced but I never want to go back in after a clutch job to solve a 2mm clearance issue of where the disc centers in relation to the PP. It's great info for hybrid owners but come on folks, if done right the first time it will last 100K. I just put a new clutch/PP/TOB/resurfaced FW in my son's 94 4WD Ranger last week...good high-quality LUC clutch kit but it still chatters right out of the box on first engagement. Sorry for the non-P car input but I'm not happy.

FRporscheman

Steve, can you explain what you mean? I've only ever dealt with 944 clutches so I don't understand what you mean about clutch centering on PP and chattering.

I think I found an rx-7 disc that will fit a 951 flywheel, I'll let you know.

I wouldn't stick junk in there, I'd only use a good disc. So I'm a little hesitant to go with Ford but I have more faith in Mazda. The Mazda disc is not dirt-cheap but still, $90 beats $200 or whatever. The ford disc was only $30.

944-LT1

I totally understand this. I just installed a new clutch in my jeep wrangler. The one I took out (that I put in earlier) had no anti-chatter control on it and it drove me nuts. The new one has the control on it and its smoooth. Just depends on which disc you get I guess. Once you get a disc, you should meticulously compare it with the old one first. But chances are that the discs are made by the same factory and then stamped later for brand names and advertised for a specific car and priced accordingly. They probably thought no one would pay 600+ bucks for a ford ranger clutch. hahaha. But they would for a Porsche!
