So would this be an okay OE+ upgrade? It should be a stiffer caliper right?

The 4-pots make slightly more brake torque (about 6%), while the 2-pot rears have slightly less (~9%).
My numbers are 65.3/34.7 %f/r for the stock brakes 66.6/33.4 with just 4-pot fronts 68.7/31.3 with 4/2 pots There are a lot of factors that might make a bias change an improvement, or not. Put on stickier tires, and you have the ability to transfer more weight to the front. Lower the car, and less weight is transferred for a given braking rate. Do both, and maybe it cancels out? Addtionally, EBD and ABS are there to try and sort things out. Last edited by jamal; 11-24-2020 at 02:44 PM. |

I would just stick with stock till you need better brakes. Better pads/fluid. CSG has great pads for our stock brakes that work really well!

As a few others have pointed out the OEM calipers are pretty good. Just need better pads and fluid for track duty.
I only went up to AP sprints for the heat dissipation and thicker pads that last longer and are usually cheaper or same price, but longer life, than the OEM front pads due to a common size and being thicker
