Clutch Press plate suggestions?

Ok, piecing together T5 parts and trying to select a decent clutch/pp combo. I admit I've run built automatics all my life so your recommendations are useful here. I'll keep it simple, T-5 conversion, 3:80 trutrac rear, and roughly 325hp out of an early 302. This motor sees 6k+ regularly in autocross which is roughly 90% of my time. I am admittedly overwhelmed by the # of manufacturers and quantity of parts. Stock isn't gonna cut it, but dual clutch is an overstatement. Suggestion on reputable performance clutches/pp would be helpful here. I'm leaning towards a diaphragm type with a lighter weight fly wheel, partly due to my aarp status.

I used a Centerforce dual friction disc and PP combo in my FF Cobra with no problems. The engine was a 331 with aprox 420 HP, custom T5 box and a 3.55 rear axle ratio. Light actuation, no clutch shudder or anything weird. It would easily boil a set of 315/35/17 tires.

I have a 164T flywheel on my 302 so I use an 11" Centerforce clutch for a FE (390/427/428). It has the standard 10 spline hub.

The first question to ask is what flywheel do you have now and are you going to stick with it?



I've started a blog about my car and adventures: http://65mustangfun.blogspot.com/

1965 Fastback, 289, Toploader 4 Speed, owned by me since June 1980. Originally a C-code with a C-4. 5R09C16****

I am no expert, but it seems to me a lighter FW would be good for autocross. Just don't go too light. The diameter of the PP will influence the overall weight of the FW. Research the weight, could take some serious thought. I would have a machine shop balance the PP/FW combo. Diaphragm PP is always my preference. Just get a good one. I run a McLeod clutch. Perfection Clutch is questionable quality. Careful about really stiff racing clutches.

That's the good parts, I haven't selected a flywheel yet, plan to run something around 15lbs, 157 tooth, 28oz, not too light to stall at idle but light enough to allow me to spin up faster. If I can find a complete combo, that would be great.

I'll be following this thread. The clutch setup I got with my MDL conversation was for a cruiser not an autocrosser. I pretty much fried it trying to launch in second gear.

65 C Code hardtop from California still wearing it's original paint.

Which one did you get? They sold me the Kevlar clutch, the car is still in pieces so I haven't had an opportunity to run it yet. If that doesn't work I guess a twin disc in in my future.

My clutch and pressure plate were listed as "Super King Cobra" that ended up being on of those decent Korean packages that are popular on eBay. I've bought similar before and they work good on the street. Given my Sciatica I'll sadly be looking at the twin disc setup.

Look at National Parts Depot. I believe they have a diaphragm pressure plate with a Long style bolt pattern. I currently have a diaphragm pressure plate and had a Long for years and I don't know that I can tell the difference.

It sucks to get old but at least the expectations are lower. 65 mustang coupe, 306, 10.4 compression, 180cc homeported Chinese heads, funnel web, t5z, 4.56 gears in a 9 inch locker
