Hopefully Luke at Tire Rack will chime in to confirm but the C1 designation means this is the Viper-specific tire manufactured by Michelin as OEM. The C1 does have some structural and/or compound differences from the "regular" PS2. I don't know what the "MBZ" designation is but many car...
Just confirming the above posts; the most recent SRT chat confirmed that the new 6-spoke rim weighs about the same as the ACR/Sidewinder/Copperhead 5-spoke rim (not to be confused with the 5-spoke rims that came standard on 08s). The ACR/Sidewinder rims weighs about 17.5 lbs front and 25 lbs rear.

Do a search using the words Belanger and Dyno or Comparison. I posted a thread a while back about this and Mark Jorgensen at Woodhouse actually some Mustang dynographs on a car with minimal break in miles (30 I believe?) that showed a gain of about 50 rwhp.

Thanks Dan. Just a question: I have always been curious as t whether these are the same as come stock on the 2008-2009 ACR. If not, what are the functional differences? For someone with a 2008 Viper who does a 50/50 mix of driving of the street and driving schools/track days, which is the...

He liked the looks and the drivetrain although he did not drive it on the street, just the dyno.

Here you go; these are sound clips before and after the Belanger installation:

Yes, there is a thread:

Looks like even with only 30 miles on the system before the ECU had time to adjust and reclaibrate for the Belangers, the Belanger system...
I have similar coverage on my 2008 convertible with something called Ventureshield. I got a bit of a discount because I have had other cars done at my local shop so the total for me was $1200.

Here are some pics and a sound clip of the Belanger system on my 2008 for those who are interested. I have been very pleased with the sound and performance benefits of this system (appr. 20 lbs weight savings, reduced heat, appr. 50 rear wheel horsepower gain):

I get plenty of rain where I live but still preferred the "surround sound" aspect of a convertible for both street driving and track days. If you are going to use a convertible for track days you may, depending on the track and the school in question, need to install an SCCA-compliant rolbar...
Hey all --
I checked my Viper with the 2-piece Stoptechs today for the "squealer" people have been discussing. Are the squealers little "U"-shaped sliver clips that look like they are attached to the pad itself? If so, I think mine are still attached but they do not appear to be causing any...
I switched to the Stoptech 2-piece aerorotors on my 2008 and retained the same pads as stock. I do not know if my Viper tech had to remove the squealers but so far after about four driving schools I have had no problems or visible damage to the hats or rotors.

Thanks once again for taking the time to chat with us. My questions are:
1. Some have posted that the 2009 model will receive upgraded/modified drive by wire throttle programming and that such programming can be retrofitted to the 2008 Vipers by an ECU reflash? Is this true and if so, what...
I thoughtI remembered a previous post where it was stated that the KW Variant 3 system that comes with the ACR is calibrated for the higher downforce that car generates.
Maybe better off with Motons or another version of the KWs?
Can someone confirm/deny this?
