New Brake Product for 92-02 models

My name is Ken and I'd like to say hello to the Viper community and introduce my company, TPM Products and the RacingBrake rotors we produce.

Our philosophy is simple - to produce the highest quality bolt on brake rotors suitable for track day use. We've seen a lot of supposed performance rotors on the track that are in fact quite the opposite and we are confident that our engineering, materials and design will show through when it counts. We have worked with several teams in other applications (mostly WRX's and STi's) with great success and look forward to serving the Viper community.

We specialize in performance cast iron formulations that increase the strength and thermal capabilities of brake rotors and use other design features to enhance the performance of the product.

For Vipers we have designed our rotors with the following features -
-Curved vane design (our tooling) both front and rear flows more air and provides additional heat sink mass

-Alloyed gray iron has 20-25% greater tensile strength to reduce belling and warping

-Rotors are heat treated to improve grain structure

-High carbon content and uniform microstructure lead to good friction characteristics and wear pattern

-Extremely tight tolerances on runout, plate thickness variation, and balance for reliable, consistent performance

-Ball end mill slotted for gas relief, pad deglazing and pedal response

-Double disc ground friction surfaces for easy pad bedding and break in

-And some bling cause we all need a little - a glossy black EDP finish.

We are very active in the racing community particularily the 'weekend warrior' who is looking for reliable products to enhance his/hers cars performance at reasonable prices. Primarily we contend that you can make a better rotor by improving the grade of iron used and have demonstrated some pretty good success with the teams we have already worked with.

Some information we do like to get is exactly how the Viper reacts to the various brake upgrades that are available. For example - does the car need more front or rear bias - what pads work well on the car - does the car tend to eat brakes (it wouldn't be a size issue thats for sure - we had to make a new box to fit them in) etc.

We also like to educate people about brakes whenever we can. For example "Should I get drilled or slotted or plain rotors?" Drilled rotors on a viper? Not if your racing that's for sure. Racing pads on a street car - not if you live in Michigan and drive in cold weather.

I asked Michael about posting here and I certainly wouldn't consider doing so unless he gave me permission. He said OK as long as it wasn't simply an ad with a phone number so I tried to present the technical data behind our products and we are always looking for end user feedback to improve and learn from.

forgot to mention....if you are running somewhere close to me (New Jersey) I'll try to be there...

For my tastes, I'd still rather have the PFC 01 front and 90 rears.
That's the setup right there. I've tried, Brakeman, Pagid, EBC - the whole fucking rainbow, but those PFC 01s stop like a mofo!!!

I'll try the AP600 Deano. The Motul has always been more convenient for me to get but I'm gonna use up what I got then move on. Motul is French anyway.

If you think the Stoptechs are a good 1 piece rotor at $389/pr or whatever they actually charge then I'm gonna put my money where my mouth is.

I'll get a car set of rotors to the first guy who wants to test them for me at a 'near OEM' price (basically the wholesale cost).

The only requirements are as follows:

You're not a jerk....I have no time for that.

You road race a 92-02 Viper with stock brakes and you run aggressive pads and preferably R compound or at least DOT R compound tires. I'm flexible here but I'm not going to whore out my rotors to a grocery getter. I need data.

You will be racing in the near future - the sooner the better.

You'll give me the details of your test...nothing too difficult just pads used, tires, event you raced at and some evaluations as compared to what you are currently using.

Email me at [email protected] if you are interested...

I heard mention of Warren's pads (brakeman). I think he is a rather smart man but have any of you hit up Larry Narcus (Carbotech) for pads?
Well, some people think I'm an asshole, but I'm not a jerk and I can drive better than most. I test brakes with Tempilaq, an I-R gun, a stop watch and the seat of my pants. I spend racing money grudgingly, and never where it isn't absolutely necessary. Unfortunately, I'm so tied up with work this year that I've only been to the track once (last Feb.) and don't expect to get there again until this fall at the earliest. /images/graemlins/sad

Carbotech was a preferred supplier to Viper Days during the first two seasons Skip took the series nationwide. I don't personally know of anyone using their pads now, but that doesn't mean that nobody is...

Can you tell me what we are looking at here?

OEM or OE replacement.....pads used, how many events on them, highway miles if any, etc.

The cracked ones look like they are done or at least very close...fronts I'd assume.

And basically ignore the 'no jerk' rule. I just want avoid giving no margin product to a creampuff as it does not help me in any way. It pisses off quality retailers who need good margins to provide service and gives me no real data to base product decisions on.

And I'll add that looking at Vipers for this many hours is definitely KILLING ME!! God I want one - even a ride in one.... anything!!
That was a before/after pic of my OEM front rotors when I went to Road America a couple of years back. The inset pic was after bedding, the outside pic is after 2 days with PFC 93 pads. It's the worst set of rotors I've ever taken off my car, and they probably had around 120 miles on them. I keep my track rotors and pads matched and don't drive them on the street to avoid glazing and warpage.
