That would be a problem especially with tracking. The s2000 rear brakes were also solid and non vented which absorbs a significant amount of heat. Definitely has problems in terms of longevity of the rotors and calipers over time. Does anyone offer a vented rear disc ?

Girodisc rotors are curved vane.

From their website.
“The rotor utilizes a curved vane design, developed in racing to act as a centrifugal pump to force cooling air through the disc.”

Yes the curved vane in the surface but the the vents in the side of the rotor is very important for cooling as well.

I am not talking about contact surface grooves / slots. The vaning is internal to the disc, in between the two friction surfaces. When it spins, it pumps air through the inside of the disc.

The brakes are a two piece design with replaceable discs and reusable hats. They are commonly used on track applications everywhere.

Girodisc does not make solid rotors (that I am aware of).

That’s why I was asking because some photos show solid rotors. I’m new to the platform so not sure for the oem 2 piece, they are doing solid as well.

The rear oem discs are not vented. I am going to call girodisc on Monday to ask. Bc there isn’t a lot of space.

yes please let us know. @ 11mm it’s not, but there are upgrades that is a bigger disk. I don’t need a bigger disk brake if I can’t vent the heat. The s2000s had these problems. Had to replace my rear calipers twice because I think it just burnt up over time.

 

[elcid79]

Well. I was completely wrong. The photos and literature are incorrect on the website.

Thanks for reaching out. Our rear rotors are not vented – they are direct replacements for the factory rotors, so we do a solid rotor as well. However, we do design them to be 2-piece fully floating units, so any risk of warping rotors should be eliminated.



Based on a lot of customers running our rotors on track, these cars use the front brakes so much more than the rears that we haven’t seen any need for a vented rear. Our rear rotors match the factory thickness, which avoids needing to machine the caliper cage or make any other modifications.



Here’s a detailed thread with good data about rotor longevity, running our 2-piece direct replacements front and rear:

I’m not convinced these cars need any more rotor in the back, and I would suggest spending that money instead on a quality set of pads like Endless ME20 or similar. If you would like me to find out pricing and availability for ME20s front and rear, I’d be happy to.



Let me know if you have any questions!

Thanks for this good information I will do replacement on mine with the giro disc instead of paragon but will run power stop pad because I definitely don’t go to track mine is purely a daily driver. But also will do the WUNDERLADEN Racing rear caliper bronze bushings upgrade to have even pad wear.

 

[ALwAyS4SaLe]

Do you have a link for this upgrade?

 

[ALwAyS4SaLe]

It’s funny they say the rears are rarely engaged, but people on Facebook groups have been reporting more use and warped coming from the rears instead of the fronts.

I don’t know if it was to me you were talking too but this is the bushings probably help with the warping of the rotors too.

Yes sorry, answering from my phone. Thanks for the reply

I can't speak to long-term rotor wear with the bronze bushings, but I do think they’re a great upgrade for the price.

I primarily bought them to help prevent the potential issue of uneven rear pad wear. I was pleasantly surprised by the improvement in brake pedal firmness.

I consider myself fairly sensitive to pedal feel, having had some close calls in the past and done quite a few brake flushes over the years. At the time of installation, I was on stock fluid and pads with around 4K miles on the car, and it felt comparable to doing a brake flush that cleared a lot of air from the rear with a race fluid like Castrol SRF. You can clearly see how flimsy the stock rubber bushings are once you remove them.
