I've only had these on my car for a couple hundred miles, but thought I'd make a thread, as I've only seen them mentioned here once.

I replaced my stock rotors due to a lot of vibration when braking at moderate to high speeds. Apparently, the previous owner of my 8 had a lot of fun with the stopping power of the car. While researching different options for replacements, I came across Trinet Motorsports. They have an eBay store (oh no!), a fairly basic website, and a shop somewhere in Orange County, I believe. After reading positive reviews on other car forums, and seeing the relatively low prices, I decided to take the "risk" of buying these. Trinet Motorsports is not one of the more well known names in braking products, but after talking to the owner and a few members of the staff there, I felt confident that their product was legit. Some will say you get what you pay for, which is usually true. But I didn't feel like spending so much more for brake rotors that I believe are all quite similar (excluding two-piece, BBK's, etc.) I will update this thread if the brakes suddenly give out, assuming I make it out alive.

As far as I can tell, stopping power is about the same as stock. However, my assessment isn't the most accurate, because my stock rotors were shot, and I also changed my brake pads at the same time as these. What I can say is that they work just as they should, and I liked the additional flair that the slotted design provides. Whether or not it affects my braking performance, I don't know. Trinet also offers cross-drilled/slotted rotors at the same price, I believe. I didn't go that route after reading of the increased risk of cracking and other problems with those kinds of rotors.

Anyways, just thought I'd take some photos and let the RX-8 community know about one more option for brake rotors. My next step: painting those hideous brake calipers.

 

I think it would be a shame for this thread to disappear into oblivion without a single response, so I'm going to ask everyone else: If you've changed your rotors, have you noticed any difference in stopping distance or braking feel? I imagine if they're the same size as stock, it wouldn't be too different. Next time I have to change my pads I may go with something a little more aggressive for harder initial bite, or some stainless steel brake lines.

 

i changed my brake pads to hawk hps. that made a difference.

i cant imagine your brake rotors doing anything though. slotted rotors help when you're tracking. same with drilled. but you arent going to notice a difference unless you are really ***** to the wall on a track for 20 minutes.

the most noticeable thing you can do with a brake rotor is get a lightweight 2 piece and shed some rotating pounds per corner.

 

So what is the update on the rotors? I was thinking of picking them up too because mine are totally warped and making all sorts of noise...

 

Your rotors aren't warped, your problem is in your pad selection and its the pads making the noise. Replacing the rotors without upgrading the pads will lead you back to the same place you are now.
