So did mine, so we just cut the front face of the flywheel back to the bottom of the groove, after all, it isn't all that deep, & presto, we had a flat flywheel.
We also cut a small amount from the back & ended up with a slightly modified stock flywheel that was significantly lighter than you would get with the same work on a 1200 flywheel.

I have a pressure plate from a Mitsubishi (of all things!) and Exedy clutch plate behind my s/c a12.And what a clutch it is!!!!!!
Get in touch with Stewart Wilkins at SWR in Mulgrave N.S.W. 02 45772400.
This guy knows his Datsuns, believe me.
And a little bird told me he taught John Taylor a thing or 10 about them as well!

No offence intended Mr Taylor!

I Had my flywheel remachined to accept an LD20 pressure plate. (NSC511) this is 200mm dia, as opposed to 180mm of the stock a series. Then I just asked a mate at BNT for a 200mm Nissan clutch plate, with 18 splines in the hole. (I took in an old input shaft to be sure I had the right thing) seems nissan must have used the same splines on some other car of theirs. The bigger clutch has around 34% more surface area than the stock a series unit.

I'll post the part # of the friction plate when I find the receipt.

My A10 flywheels have a ring groove cut out of the ares where the friction surface of the clutch would go
So I couldn't use it in my racecar

Quote: I beg to differ as the 1200 flywheel is the SECOND lightest of the A series flywheels.
If one is going to machine the flywheel to use the larger clutch, then you may wish to use one from an A10 engine as these are in fact the lightest of the stock A series flywheels.

daikin heavy duty kit will be more than enough...if it was enough for 1200rc with the a15tt then it can cop a fiar bit of abuse, ultimately it did slip but is still working fine behind my stock as a rock a12, no slip and not glazed or scour marks on the cluch faces.

Prop's to Mr Berry . . .

For a serious A15, Go an 8" clutch, 180B HD Pressure plate I would suggest, a Jackaroo/Gemini Clutch plate will suit the A series g'box splines.

Get an A12 (lighteset) flywheel re-doweled and while they are at it, get them to throw a 20 thou step in it to help out.

Fits nicely inside the A series bell-housing. Same throw-out bearing and all.

And for the 63A users, jsut use the standard 180B clutch plate. . .

Pressure plate and Clutch plate should get you change from $200 as should the machine work for the flywheel. Less if you know someone in the game.

You won't have to revisit.

I can highly recommend Race Clutch here in Brisbane. They freight Australia wide. Jim Berry has forgotten more about clutches than most people will ever know.

Ok well thats a strange clutch to have in a Datto
Since its for a Ford Laser
You sure about that number ?

Perth Brake Parts is an agent for Extreme clutches. They don't carry any in stock but they can get one in for you
However..... making sure you have the right thing to start with will be the issue
They sell boxes with clutches in them... they don't mix and match parts.
Their clutch experience is very limited as they only started selling clutches in November.

Maybe take the clutch to Graham at The Clutch Factory (Precision Clucth) in Dowd Street Welshpool and get it identified first
They can build performance clutches there too
They did the one for my racecar with A series engine and Toyota box and clutch.

You should speak to the guys at Xtreme clutches in adelaide, they are pretty on to it when it comes to older cars, arent too cruel to your wallet either.
