Do you all think there is any need to use anything other than stock brake components for folks that are driving 100% street?

Where can you get these brackets?

If u track often say once a month, One peice rotor will crack no matter wat kind or brand u get. I have fist hand experience on this. Ur car is super charged so it's gana crack even faster. That torax kit u guys r talking about iv never heard of so idk about that but I wouldn't wana risk brakes for any unknown brand for brakes. When u loose brakes on track, u never felt this alive in ur life. Plus putting a 6 or 8 pot caliper on OEM sized rotor speeds up the cracking process of the rotor. I have tried the spoon calipers with spoon rotors. Cracked that rotor in 30 min. To keep ur oe wheel and have great RELIABLE breaks is hard. Maybe try wilwoods dynalite kit with 2 peice rotors. But idk bout the fitment. The brake ducts do help but they help the pad out more than the roter imo.

I'm going to be going with the Acura Legend GS calipers. I have the exact same issue, I really like the AP2V2 wheels, they look perfect on the car, so I don't what different wheels, but the clearance is very tight on them

They're really made for single sided calipers.

The Legend GS calipers are a two piston style with two pistons on the inside, so they're have no issue clearing. They are also supposed to be a bolt-on if you have the right bracket, and should work well with the 28MM Acura NSX front rotors. I think the Odyssey and a number of other Hondas also run 28MM rotors.

Here's a link to swapping them on a 6th gen Accord. Note, lots of people swap the 6 gen accord calipers on the S2000, so these should work. The Legend GS calipers are also really cheap, like $100 a piece, and will give same clamping as a 4 piston calipers. They just don't cool as well, but with a thicker rotor, it should give a tremendous improvement. I still need to get the exact size of the pistons, but I think the Legend GS calipers will work very well with the Sakebomb Rx8 rear caliper conversion.

Piston sizes:

Legend Calipers 42mm and 38mm piston sizes.

NSX Calipers 40mm and 34mm piston sizes.

-- rear piston is 38mm on Legend GS.

-- evidently the rear is also 38mm on S2000. The RX8 rear caliper looks like its 43mm. This means the rear area on S2000 is 1134, and RX8 is 1385. That's 20% larger than the S2000.

That means that the Legend GS dual pistons have 10% more piston area than the S2000. So to fit the LegendGS you definitely need more rear brake area.

Factory S2000 ratio is 2290 / 1134 = 2.01

With the Legend GS calipers up front and RX8 in the back, this becomes 2520 / 1385 = 1.747, but Legend GS up from and factor in the rear is 2520 / 1134. = 2.22.

I just don't know if using the Sakebomb RX8 rear kit even with the Legend GS calipers will give too much rear brake bias.

What's interesting is the 97 NSX went to a huge rear caliper piston size, which looks like it gave it a huge rear brake bias shift. I don't know if they compensated for the much larger rear caliper with a different proportioning valve.

Would love some pics later on if u plan on installing. Oh and btw the game caliper cannot provide the same amount of bite and endurance wear as a bbk. But yes they r far superior than S2k calipers.

I don't know, the Corvette seems to stop just fine from 170 MPH+ with two piston calipers, and it's a heavier car that the S2000.

I am definitely planning on the Legend GS 2 piston up front and the Sakebomb RX8 in the rear, but I won't be able to get to it for some time, I've got zero time at the moment.

The guys at Sakebomb said they could provide a custom proportioning valve to set the rear brake bias.

Lol. Corvette has like 13 inch rotors that are 2 inches wide

FWIW....................After I installed front brake ducts into my car in 2001 I tracked my car giving instruction or just lapping for at least 3 days per month for 6 years at numerous tracks around the mid-west and only cracked one rotor at Road America.


Tarox designed the kit that I use especially for the S2000 in both a 16" and 17" OEM wheel fitment configuration in conjunction with the European S2000 owners group. You will see it discussed on this forum most frequently in the UK forum. I think that their kits have been out there for more than 5 years.

thats good to know. Maybe someone will give thier personal option on wat they think of torax. Btw idk wat track u run but in NorCal we have some tracks that will snap oem rotors in a day when u running really fast times. We have a 120mph+ straight leading to a sharp v that u take at 40mph. Im also taking about Running Race Pads with oem rotora like compound a, dtc60 or carbotech. Not oem pads. The race pads will REALLY ruin ur oem rotors asap. Especially dtc60.
