I came across this today and don't think I've seen it mentioned on here.

Dual Master Cylinder Brake System from OBP Motorsports

Looks like Pegasus might be a retailer of their products.

Anybody have any experience with OBP Motorsports in general to know the quality of the product?

 

What is this the solution to?

 

If you have to ask what a dual master cylinder setup is for, it's not for you.

That said, it allows you to adjust front/rear brake bias and eliminates the power brake booster. It would be an alternative to putting in a pedal box setup.

 

Okay, understand now. The car comes with a dual master cylinder. What you mean is one with a bias bar.

 

I'd call it a tandem master cylinder from the factory. But sure, either way, it provides bias adjustment with a bolt in solution.

The need for such a part has been mentioned on here in other threads and it looks to be a new part just recently released.
