Default C beam reinforcement plates

What was the verdict on these plates? Do they really help? Where's the best place to get them? I see Zip has them now, but for $179. I just figured while I have my car all apart, now would be a good time to install them.

The price has always struck me as very high for what they are, however I still want a set. After you fight trying to tigthen the torque arm bolts a few times and you can truly see the benefit of a product like this.

TIghten the torque arm bolts as tight as humanly possible - Beyond what the service manual calls for.

I tightened mine to spec and they came loose!

I recall posts about broken noses, chipped teeth , from tightening this thing.

I am sure the beam plates will help. Let us know.

I put a set on from zfdoc and they really do work. I autoX and do track days and would not be without them. Expensive but worth every penny!

I agree the price is a little high, but the labor savings for a DIY'er such as myself, they make the job easier. If I spend 2-3 hours on several attempts to get that damn torque tube tight, then how much are they worth?

I've put two clutches in my car.
The 2nd time I went out and got the beam plates.
OMG! was it easier putting it back in!

They're worth it.
It's a lot stiffer now too.
Quality peices, nice finish.

I had no difficulty tightening my c beam bolts.

There's plenty of room to put a large crescent wrench on the upper nut while sinching the bolt tight.

So... all these do is keep the bolts from coming loose? Sounds expensive. What ever happened to using safety wire!?

:iagree:

And I have them on both of my cars now - but they are really intended to limit flexing of the C-beam which is supposed to reduce the tendency of the rear end to kick out to the right under hard acceleration.

I guess I am missing something here, but why couldnt you just take a steel plate, approximately 2in. X 5in. , drill two holes in it, and weld the nuts to them? Would this not do the same thing?

Sure, knock yourself out. But for some (most?) of us, by the time you get all the hardened fasteners and steel stock, measure and cut all the pieces, grind edges, jig them, TIG weld them, bead blast them, you've got 4 or 5 hours into it. Granted you might not want to make them look THAT pretty, but then if you were buying them from a retailer, we expect a good fit and finish.

Here's a pic of Beam Plates done right. These are from Bill B. (ZFDoc):

You can't put that much detail work, TIG welding, & processing, into a hand made stainless steel item & sell it for much less. That is if you plan to make a profit. Our going rate is $62.50 an hour - material & labor.....

93ragtop...you aren't missing anything here. You are right. It won't be stainless steel, it won't be 'beautiful' though.

Find a buddy that 'fabricates' and you can make a decent set in probably an hour (and that includes having a beer along the way) out of plate steel. Or get a piece of scrap plate, cut and drill them yourself, grind the edges a little, and then take it all to your local welder with $20 (heck probably $10 would do it) and have him tack the nuts on the plate for you. All the commercial ones do is allow you to probably use the stock bolts. Oh, yeah, they look pretty too and don't rust. I'll spend a few hours any day to save $140. Over the years $100 here and $100 there can add up to some big bucks that lets you buy more toys (tools in my case).
