I had some lengthy discussions with Tarox's NA Sales Manager as I was frustrated in trying to find a 2-piece rotor big brake kit besides the Wilwood that would work with OEM rims. Pumaspeed lists a 325mm big brake kit from Tarox for the FiST but it does not fit without wheel spacers. Their smaller 300mm big brake kit includes one-piece rotors and no weight data really compare to stock. I am not interested in the Wilwoods as the rotors are actually much thinner than OEM which is a no-go for me. This thread is NOT to dig at Wilwood, just to note there is another option that is not readily visible to folks who choose not to go with Wilwoods. Wilwoods' price is much lower than Tarox indeed.
After some digging on the Tarox website, I noticed that there are actually 3 different kit numbers for the FiST: KMFO1141, KMFO1141T and KMFO1142. Pumaspeed and other online vendors only list the KMFO1141 and KMFO1142 as available, so I reached out to Tarox for clarification.
Turns out, Tarox actually DOES offer a 300mm big brake kit with 2-piece rotors! They have not sold it in the USA yet but are just now offering it out. The KMFO1141 kit is the one-piece 300mm set, the KMFO1141T is the same kit but with lightweight 2 piece rotors and the KMFO1142 is the larger 325mm kit with two piece rotors. Pricing on the KMFO1141T is the same as the KMFO1142 kit per Tarox.
The best thing is that the KMFO1141T and KMFO1141 kits should both fit behind OEM 17" wheels WITHOUT spacers! Tarox provided me the attached template to double check the clearance which I will be doing with my OZ Ultraleggera 17x7 ET42 wheels, was curious if someone else would be willing to print this and check for OEM wheels so we can let Tarox know fitment there too? The KMFO1141T kit should be about 20lbs per side total give or take a pound, so roughly 10 lbs lighter than stock in total for the fronts despite the increased rotor size.
Some of the important details about these as compared to the Wilwood option I checked are listed below:
- Wilwood rotors are 20mm, which is 3mm (13%) thinner than the OEM FiST rotors.
- The KMFO1141T two piece rotors are 24mm so a little bit thicker than OEM FiST rotors (4.3%) and about 4mm thicker than Wilwood's (20%!!).
- Both should fit behind OEM wheels but we need to verify this.
- Pricing for the KMFO1141T kit is $2280, so definately a much pricier option than Wilwood, no arguments there at all.
- Tarox confirmed the big brake kits fit all global FiST ST models since it is a global platform (2014-2018 I believe).
- Colors available include metallic green, blue, red, silver, gold/yellow and black for the Tarox kits.
- OEM caliper, rotor and hardware is about 25lbs per side.
- Tarox B-30 6 Piston Calipers weigh in at 6lbs each.
- Tarox two piece 300mm rotors weigh in at 13lbs each.
