So since I'll be taking my engine out, I thought I would take the opportunity to install a reinforced clutch arm. Especially since I have an uprated pressure plate.

Most of the reinforced arms have a piece of plate steel welded across the front, over the dimple where the pivot sits. But I've also seen a few (like the picture) that have strips added to the sides as well. Does the arm need reinforcement there as well?

I've also seen recommendations of welding a washer around the dimple area, I assume one sized to accommodate the dimple. Is that needed, if I go with a plate across the whole thing?

Thanks!

Never seen one bend, but I have seen the rod push thru the dimple several times. That center force clutch takes a lot of leg to move. Ted has ones made up that don't require the same effort. A friend of mine has one in his TR8, and I like it. In fact I plan on installing the same one along with Ted's aluminum flywheel into my white 4.6 coupe. My friends car makes over 300 ft pounds of torque from 2800 to 5400 rpms and Te'ds clutch works perfectly. I'm intrigued by the clutches made by Spec. Just waiting for one of you guys to be the guinee pig.

Thanks, I'll just worry about the reinforcement across the dimple.

Maybe Woody changed what pressure plate he provides, or I'm stronger than I think, but I really didn't feel any difference between the stock pressure plate and the Centerforce. And both are lighter than my TR4A. Not in Honda category, but not what I could call heavy, either.

Update, I got my new clutch arm from Rimmer Bros, and it is already reinforced.
