I heard about this animal. Any links to their site? I'd like to get some additional info.
This is the product that helps your car go forward under heavy acceleration instead of having the butt kick out?

Re: GP on ZFDocs C4 Beamplates? (bogus)
These multi-purpose driveline support reinforcement plates can be used on all 1984 through 1996 model year (C4 or 4th Generation) Corvettes. We have found that most C4 Corvettes inherently experience a slight amount of twisting at the fastening points of the support beam to the transmission and differential housing connection surfaces. Although fastened with high grade bolts, self-locking nuts and adhered with factory sealant, the driveline components of the C4 Corvette still experience some level of counterforce load-induced lateral deflection between the members while under heavy loading. This allowance of flex in the driveline beam fastening joints creates a condition where the chassis structure must additionally contend with. One common side effect of this phenomenon is where the rear of the vehicle tends to kick out to the right during aggressive high RPM gear shifting. Notice that the C5 or 1997 and newer Corvette was redesigned so that lateral deflection of the driveline is practically non existent. The C5 Corvette driveline consists of a drive shaft within a tube that has a bell housing fused to each end.

I am not sure how they work either but I have heard enough people say good things about them that I would sign up for this GP...
I hate looking at the wall at the track... :nono:

I've always wanted to fab a set, but heck if the price is right count me in..
BTW, Vvcdde I went to your web page & that's one cool looking car you have there, those black Fiske wheels look really good against the silver paint.. :cool:

I have a set on my car... Work great!! :yesnod: :yesnod: Rkreigh sells them cheaper by ~$20 or so... He buys 50 to 100 at a time and sells them.

If you guys talk to rkreigh from the ZR1 section you may not need a GP... I saved at least $40 of RRP by dealing direct with Ron.

I have never quite understood how these work compared to just making sure that you have your stock rear torque beam bolts torqued correctly.
:confused:
Anyone enlighten me or have an easy to understand link?

Re: (scorp508)
I'm with you Scorp :iagree:
Being a structural engineer, the only thing these bearing plates do is to spread the load along a much larger flange area of the C beam instead of just around the perimeter of the bolt holes.
If your C beam bolts aren't properly torqued though, the differential pinion shaft and housing will tend to rotate upwards under heavy load due to the slop in the connection to the C beam.
These stiffener plates can't hurt, but the price looks steep for what they can do. I would check bolt tension first, then have someone who has this product test it with and without.
Oh, and BTW, any structural or mechanical engineer will tell you that an open shape member is very poor in carrying any torsional loads (that is why they use a torque tube in the C5....it's a closed shape).
Fact: The C4 C beam or channel is used to support the rear of the tranny and the engine....it offers very limited torsional rigidity :eek:
Just my 2C :chevy
