Already fixed. Got a beefier RX-8 hub on it now. It's my daily.
Yeah after I saw you dropped back I thought you were cooling it off. When you get the car sorted and start trusting it's tossability I won't be getting as much video of you.![]()
nice video man. that second time you went to point me by I missed a shift and managed to drop the car into second somehow and noticed the water temp was 240. I was trying to find the line that works best for the miata, i don't normally go that deep into the corners before turning in. For the next sessions i borrowed the line you used when you passed me early on and i think that works much better. the car carries enough speed in corners it likes an early turn in.
I also realized the car doesnt like passengers. The passenger rear was rubbing like crazy that session with a passenger in the car. You were driving the crap out of that thing. You going to be fixed in time for the toy run?

Bolt onto NC's. Need 2009 RX-8 or newer for the ABS sensor.

So I'm just now reading this thread. Shanem, did you try taping up the hole at the Toy Run? Did that help?
What's the logic behind pointing the ductwork at the hubs? Not sure I understand why you wouldn't point that stuff right at the rotors. I'm sure it has something to do with pressure, but I don't get it.

The hub is a heatsink to the rotor. Cooler hub draws heat faster off the rotor.
yup that and the fact air is a poor conductor so it takes longer to transfer heat away from the source than more metal can, hence heatsink.
I have a factory bar just like yours.
Yes, I see that. But, I thought I had to install a full roll cage to be able to run in any events other than the Toy Run. So you're telling me that's not true? If so, that's great news. I have the PRHT and have been looking for some sort of solution so that I could do track days in the car. I don't need to do that???
Michael
you don't need a full cage, most just require verts with no hard top to pass the broomstick test. ECR does enforce that convertible rule for its own track days AFAIK. that video was from the 5 star track day, which was a private event and those private days are typically run like a member day, meaning rules are more lax. it mostly has to do with instructors not wanting to get into a vert with no roll bar with a new driver.
Sweet. There may be hope for me yet. :)
ken o and I talked to a Brembo engineer at the Caddy COTA event. Their data doesn't back this assertion up.
The design of the car and the rotor venting plays a large role in this, but based on talking with this guy I'm not convinced that the hubs see near as much heat as most people think they do.
FWIW, this would be a great place to try some heat tape to actually measure the temps.

If I do ducting to mine I will run it to both rotor and hub. I'm on my first rotor (soon to be replaced due to wear) and my third front right hub (now an RX8].
