Question about brakes

Hello everyone,
I'm french so excuse me for my bad english.
I have owned a 2007 Viper SRT-10 since 2009. I have done quite a few trackdays with it (Magny Cours, Le Mans...) and I stopped since 2020 (long live COVID lol).
But I want to return trackdays at the beginning of 2025. And so I have to start again with new brakes (I have Michelin Pilot Sport Cup for info).

In 2011, I have two-piece Stoptech discs. I loved it. But the parts no longer exist it seems.
I put in 2015 grooved EBC discs with yellow EBC pads but I found that they lacked bite. Better than original but lower than Stoptech.
Parts Rack offers me grooved Giro discs (associated with Brembo pads). Do you know these discs ? As good as Stoptech?
Thanks for your help.

Oh boy, here for the

There never was a Viper built in 2007.

Next, you can find plenty of discs available, but you need to confirm some basic counts and measurements:
1) diameter and thickness of the rotors
2) width of the disc face on the inboard side of the rotor
3) number of fasteners holding the rotor to the hat
4) are the disc holes slotted for floating pins, or round for direct mounting?
5) bolt circle diameter of disc holes and diameter/thread pitch of those fasteners

Once these are confirmed, it narrows down the additional search parameters needed.

Thanks for your answer

The "2007 Viper" has come up in more than one location. As I recall, this designation has generally been used by a few people discussing EU vehicles. If I am on the right track here, that may mean the car would be designated by the year of registration by the MOT, DOT, etc. versus by the 10 digit of the VIN

Just a thought.

Girodisc is a great option for track use as they are a 2 piece design and have vanes to extract hot air out of the rotors. Brembo pads are also a great option, but they are very dusty compared to other brands (Stoptech, Hawk, etc.). I am a fan of Hawk HPS 5.0 for street & track use, but you could get a track pad an swap them in for track days as it takes about the same amount of time to swap pads as it does to remove a wheel.

I finally wore out my Stoptech rotors and the Girodisc rings were what I had in mind to replace them with. Haven't gotten around to it, but them seem like nice enough pieces and they have some of the best prices I can find for the rings.

As for pads, everyone will have their preference. I only tracked my car once a year in the past, so I was using a dual purpose Stoptech street pad. Seemed to work well with my braking style on the track I ran, but they were a little dusty. The last time out I finally decided to give some real racing compound pads a try and bought some Carbotechs. Definitely a noticeable difference to a novice like me. The main thing I liked about them though was that they also offered a street pad with a compatible compound, so you can swap them back and forth without having to re-bed them or anything like that. The street pads are pretty nice as well and are generally pretty quiet with good bite, though you can tell they don't want to bite initially if you drive in the rain for a while. They come back within one stop, but the first pedal hit after driving on the highway in the wet is always a bit of a surprise (stiff pedal, but not a lot of stopping power). Side benefit of the Carbotech stuff is that the dust is supposed to be non-corrosive, so it won't eat wheel finishes or anything in the suspension. Lots of different compound options as well.

Honestly, the stock Brembo pads were some of my favorites. Great bite and they even worked pretty well on the track, but like others have said they dust a lot and they are quite expensive.

These fit on Stoptech hats.
