FOR SALE: Beam Plates from ZR51 (Bill B.), brand new...
I cant believe I just found these in my garage.....
My 96 C4 has been gone for a couple of years . I had purchased these for the car and NEVER installed them. They are NEW and still in the plastic wrap they came in.......perfect for any high performance C4.
I did alot of research and even drove a few C4's with them....they definitely WORK and are extremely well made.
These are nearly $200 NEW but I am asking
$135 plus shipping

C4 Beam Plates (Fits all 1984 -1996 Corvette Drivelines)
Lifetime Warranted Retail price - $189.00 To Purchase call (602) 319-6575 or email www.billb@zfdoc.com
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.
Customer Feedback: Hear what customer's have to say about this product.
Better Handling: The stainless steel TIG-weld constructed design provides high torsion load reinforcement of the only two flex prone areas of the driveline. By reinforcing these areas, the vehicle’s suspension system will experience less torsion load interference from the driveline system. The noticeable improvement in acceleration handling will provide for better directional tracking and predictability especially when at the edge of the performance envelope.
Simplifies Driveline Beam Service: These plates also simplify removal and installation of the driveline support beam by providing a topside wrench-free design that, when both bolts are started by a thread, allow the installer to use both hands below where the torque leverage is needed.
Specifications: Material - 30302 stainless steel, Construction - T.I.G. welded, Fasteners - New GM self-locking nuts, Weight - 1.65 lbs. (per vehicle set), Finish - Silicon bead blasted
Q) How does lateral deflection between the driveline members affect the vehicle handling?.
A) The immediate area of the driveline beam around the bolt and nut heads where the beam fastens to the transmission and differential are prone t flexing a finite amount. With the slightest amount of flex or deflection occurring at these joints, counter-force torsion energy is off-loaded to the chassis. This brief spike of counterforce energy causes unnecessary deviation of the suspension planes. A brief change in the drive wheel thrust angles is the root cause for the C4’s inherent response of the rear end kicking out to the right when aggressively shifting during heavy acceleration.
Q) How do the C4 Beam Plates improve the vehicle handling?
A) By installing the ZR51 Performance C4 Beam Plates, the driveline system becomes more rigid and less apt to affect the suspension system during extreme loading.

C4 Beam Plate Installation Instructions: (P/N 1052C4BP) (Now comes with 2 driveline clearance checking blocks.)
Raise vehicle and suitably support.
Remove partial or complete exhaust system if necessary to achieve clearance for removal of driveline support fasteners.
Support transmission and ready a secondary support device beneath the differential. NOTE: Removal and installation of the driveline support fastening bolts normally requires manipulating of the transmission and differential mount points. A second jack or lifting device is recommended.
Remove support beam fasteners, placing nuts and washers aside. (Do not re-use washers for they will not allow enough thread-depth penetration for the locking nuts to fasten securely).
Clean the upper and lower surface area where the C4 Beam Plates will be seated.
Carefully work the Driveline beam away from the Differential and extension housing enough to inspect the contact surfaces. Any surface irregularities must be removed.
Carefully restore Driveline beam to its original location (Included are 2 small sticks of metal that can be used in the next step as clearance "go no-go" gages for checking the support beam location/clearance within the tunnel.
Insert bolts through lower plates noting that the front lower plate has a relieved corner for speedometer bulkhead clearance. Position the plates (w/nuts) at their proper locations on top of Driveline beam. Insert bolts (w/lower plates) through the holes and hand start the threads by 1 turn into the top deflection plate.
ALIGN DRIVELINE COMPONENTS: Take the following measurements directly above and to the right of the Propeller shaft front yolk universal joint. To ensure proper alignment of the driveline, a clearance of 45 mm +/- 6mm (1.77 in. +/- 0.236 in.) must be maintained between the top of the support to the underbody and a clearance of 28 mm+/-6 mm (1.1 in. +/- 0.236 in.) from the right side (passenger side of vehicle) of the support to the side wall.
Tighten support bolts at carrier to 80 Nm (59 lb. ft.)
Tighten support bolts at transmission to 50 Nm (37 lb. ft.).
Remove transmission support(s), install exhaust (if removed), and lower vehicle.

Jakers - according to the UPS calculator from me 77077 to you 31820 is about $14.50 or so (5 lb package or less , guess). You are first in line.....let me know via this thread. If you are a go , give me an email addy and I will email you.....
grinditout, you are next in line if Jakers is a no go......
Thanks for the interest from you both....

Finally...
Mike had a hurricane chase him around Texas for awhile and I flew to Cabo San Lucas and hung out at Cabo Wabo for a little vacation! Payment mailed out today! Thanks Mike!
