Venom F14 '03 Cobra Brake Kit - Installation
They arrived today! They are huge. OEM GT500 14" rotors with the Brembo monobloc calipers.
I hope to be putting them on over Memorial Weekend. I will post measurements, weights, installation pictures, etc.

Technically the Venum Brembo caliper is a better caliper and has better pad availability, it is a very well thought out kit, even replacement parts are available and reasonable.
I am checking on a couple guys that have done the Roush/Alcon 14" kit and have reported that the 95R 17s(which I have) clear the kit just barely, but require moving the stick on wheel weights, yes they are that close.
If I can do 4 piston 14s without replacing my entire wheel and tire inventory... 14s would become do-able much sooner.
Here's a post on corral and the pic. I'll be looking at GT500 rotors w/ shimmed Roush/alcons instead of the outrageously priced Roush rotors.

That's a lot of leverage for not a lot of money, if we can get away with keeping our 17s.
If we don't have to convert to 18s the savings would potentially accommodate new 17" race rubber. if the 17" race scrub source has dried up.
Less rotating mass too. I am taking a serious look at this.

Gotta ask, besides looks, why add all that additional unsprung weight and 18" wheels versus the 2000R Brembo's and 13" rotors?
With Carbotech XP16s and no brake ducting, I couldn't find a fault with 2000R setup at VIR, Watkins, NJMP or Summit..

I want to try and pull off a 14" GT500 rotor / 4 piston Alcon caliper inside 17" wheels to save both money and weight.
This cart shows the results of the heat testing of the Venum kit:

subscribing. anyone know if the roush/alcon's will clear factory 03/04 cobra wheels? Stage 5 still has a handful of these kits left and they're practically giving them away, FWIW.

Jimmy, nice chart. Do you know if those heat comparisons were with 17" or 18" wheels?
I'm wondering if the tight clearances around the 14" rotor veins on a 17" wheel would hinder cooling over an 18" wheel?
05-24-2010, 08:09 AM #18
That chart was generated with 18" FR500s.
I would imagine temps to increase by some % if you stuffed rotors tightly in 17" rims. I have to believe the vented benefit would suffer from lack of open air.

The 14" alcon set up will NOT clear the 03-04 cobra wheels, the wheels have a lip on the inside that goes from the outboard side in about 2". This lip prevents them form going on. I tried it this weekend when taking some pics for a up coming thread.

Just thought that I'd chime in and let people know that my Baer 4piston caliper which is the same as the Roush one and built from Alcon with 14'' rotors fit with my stock 98 wheels, which were 17''. Just thought I'd through that in there

I have yet to fade the 13" 00R system with real race pads and high temp fluid installed running RA1s. Not shooting down the idea... I love lower cost options and a wider range of options period.
'm still scratching my head trying to find the benefit in going to that brake setup. I'd want to know the following:
Cost for replacement rotors/pads?
Braking benefit versus other options.
At least, before I'd put down any coin. YMMV Either way, I'd love to see a set fit and hear some real world benefits once you get them up and running!

Greater brake torque(tire limited)
Longer rotor life
longer pad life
I don't have them so I can't prove squat.
I can tell you that my pads lasted longer after adding cooling ducts and I am assuming this would be somewhat similar except that additionally, depending on tire compounds, the stopping distances should also be shorter.
Think GT500 brakes in a slightly lighter car. It's primarily a leverage thing.
The rotating weight is a detriment. The use of 17" rolling stock would greatly reduce the weight downside. Wheel choice would be extremely limited.
I don't have a problem running 95Rs if that's what it takes.

Enkei RPF1 might be a good, lightweight wheel option to try here They have a 17X9 in +22 offset.

That rim looks great and I will bet they are reasonably light.
I need to find out if after centering adjustments are made with the Alcon to accommodate GT500 rotors, is the spoke clearance still there for the 95Rs?
Sorry about crapping up your thread with this Alcon stuff sonicmach1.
I got wound up about 14" brakes and kinda got carried away.
