I have a dedicated road race FD. I am looking for a way to put spherical bearing in the rear shock mount. I have yet to find a company that offers these for the FD. The C5 and the Viper share similar mounting and have options like the link from Pfad that I posted below as a reference.

Corvette Rear Shock Spherical Bearings - Pfadt Race Engineering

Does anyone know of a company that offers such a product for the FD?

Thanks!

Didn't Feed used to make some of those?
Found these Googling SUPER NOW Rear Pillow Ball Upper Arm Bearings Set Mazda RX-7 FD3S - RHDJapan

I wonder if you can't just find some off the shelf spherical / pillowball bearings and press them in. I'd check with TriPoint and Pettit and AWR if they have any.

Something like this?

These are on all 4 corners on my FD.

Those are similar to what I have on top... thanks for the link. Those are a nice product.

The bearing I am looking for is the one on the lower mount of the shock.

What would be the main benefit for this mod, I'm assuming more consistent handling and less deflection? would there be other places more beneficial to modify than this to prevent that? Assuming all if not most of your bushings are upgraded to polly or solid bushing....

I wouldn't call this a 'mod'. this is standard practice in race preparation for a race car. You don't want this on a street driven car.

The result is less deflection in suspension parts and more accuracy and immediacy between steering inputs and what happens at the wheels. Good for racing if you have a really good shock setup that can handle the increased input that will be transmitted due to solid bushings. Bad for street car. It'll shake itself apart and be loud.

My Penske rep told me that there is a lot of movement in the 0-.5inch suspension travel around a race track. The rubber absorbs a portion of this not allowing the dampeners to do their job at this part of the suspension travel. He stated that getting these might be the difference in getting on the gas a few tenths faster in the exits of turns. At my home track (Road Atlanta) this can be huge every tenth at 7 turns into miles per hour around 9.

I am with gracer7-rx7 in that this would be terrible on a street car. Terrible might actually be an understatement of how awful it would be to ride quality...

I would also only do this on full race dampeners - Penske, Moton, etc.

It looks like I am going to be getting some custom machined at this point. Since it doesn't appear that anyone sells them...
