Front brakes 2 vs 4 piston calipers

[Dustinp]

I have a 2400 pound mid engine car that I will be building new spindles for. Car came with RBP 2 inch hollow brakes 9 inch rotor and 2 piston calipers. For a 2400 pound car would I notice the upgrade to 10.5 or 11 inch rotor and 4 piston calipers?

Sorry should have noted the front tires are 10.75 by 15 razorbacks.

I have a similar size vehicle and did the upgrade you describe. The 2 piston brakes worked fine but were underwhelming. Upgraded to the 4 piston and stopping power felt night and day. I lead most the time and really love the immediate front locking up when grabbing brake pedal. I have a single master cylinder for front and rear brakes so it's biased to the front and I can't adjust it but I don't think I would.

In my opinion it's a worthy upgrade and I would do it again.

Thank you. I lead allot as well and every now and then those brakes come in handy.

More brakes you can fit the better.

brakes are over rated ...............

you scored on that car. just upgrading to 4 piston over 2 and keeping same rotor diam is a help.

Went ahead and got the 11 inch rotor. Have to make some new spindles and will get 4 piston calipers. Thanks for the input.
