Bill,
Thanks very much for the professional information. I really appreciate it! Also, I like the backbone stiffeners that I purchased from you some time ago. These really do make a difference at launch and hard 1st to 2nd gear shifts. I have recommended these to several already.

Yep, these things work great. Of all the bolt on crap you
can get for your car, it is so refreshing to install
something you can actually FEEL for a change! :)

FYI, I have Bill's C4 driveline reinforcement plates installed in GS #633 and can attest that they perform as advertised. The car launches straight and the 1-2 shift is much more controllable now.
Now if he only designed an item to increase driver skill accordingly!           -Hutch-

Rusty, I'll endorse Bill's driveline reinforcement plates anytime. They definitely improved the way the car FEELS at launch and that critical 1-2 shift. Before, I had a severe torque-twist on the 1-2 shift that made it feel like the back end really wanted to jump to the right. Very disconcerting. That feeling is now GONE! The car now jumps forward instead of sideways.

I like "Slingshot Plates" as a name for them. Not exactly self explanatory, but that's what they do to the car!

Installed a set of ZR51 Driveline Support Reinforcement Plates.  What a difference!  No more side stepping on the first to second shift.  Installation time was about two hours with hand tools, two floor jacks and jack stands.  Two of the driveline bolts, one front and one rear, were barely greater than finger tight.

 

 

Bill,
Finally got the transmission back in the ZR-1. It works great! Thanks for the professional work. The shifter is also great. I can almost shift with two fingers.

I would not hesitate to recommend your services, you are top notch. I wish every one in the automotive business did as good of work as you do.

Thanks again

<< I have been having a problem with my trans moving around a lot.  I installed Bill Boudreau's C-beam plates front and back.  They worked just as advertised.  No movement and stayed tight.  I was impressed. >>

I was studying the plates Bill makes and it occurred to me he hasn't mentioned the one benefit that may be the biggest benefit of all. We've read about C4's where the shifter goes up and down on acceleration and others that have the bottom 3 bolts pulled out of the tail housing. When you jump on one
of these cars the beam wants to raise the trans and the engine weight plus acceleration wants to push the back of the trans down. If there is any slippage in the front beam bolts, it acts like a pivot point and twists on the tail housing, pulling the lower bolts out. In my opinion, anyone that has a ZR-1 and likes to stomp on it occasionally, sure ought to get some of
Bill's plates on sooner than later. Not a paid message, just my two cents.

Best Regards,
