Some time ago, I bought the adapters to fit Wilwood 4 pot forged superlite internal calipers with the OEM disc size on the front. I have come to the point, to actually do the mod as I am slowly getting the car ready to be a dedicated track car. I am looking at that product line and trying to understand the effect on the car.

Now my question: in that product line, there are several different piston sizes, and the ones normally used in the complete kit, is the one with 1.62inch pistons (so 1.62/1.62 with 4.12inch piston area), which should already be more (9%) than the OEM caliper. Now am I wondering if it would give a negative effect, if one was to use the version with 1.75inch pistons (1.75/1.75 with 4.80inch piston area. I know bigger isnt always better, but I am trying to understand what effect it would have on the car in my use case (track use).

I have the 1.62/1.62 combo and have used this on the track . I've had difficulty with front brakes getting hotter than the (stock) rears so you definitely don't want to go bigger. I've also tried the next size down .... that was a terrible combo with rears getting way too hot.
