The KSport brakes were bought as a kit designed for the MR2 as were the Wilwoods.
The Wilwoods were installed on the MR2 quite a few years ago and I never had any braking issues with them. They came with Wilwood brand pads.
I have yet to install the KSport kit as my MR2 project has been on hold for a long time now. Though I am expecting them to work well if KSport are selling them as a kit for the MR2.
If I find any issues then I will have to adjust the front/rear bias.
By the way, the KSports came with Ferodo 2500 pads which are supposed to work well on the road.
Going back to the Yellowstuff, I just didn't feel they suited my style of braking from cold.
If I am not happy with the Ferodos then I will definitely be using Redstuff pads again.
I was originally going to buy the HKS stroker kit as it was cheaper, but it was not available.
The JUN kit came with some nice Cosworth pistons that JUN must have had Cosworth make for them.
