    How to get downforce on 2001 GTS?

    The downforce improves your grip so you can break harder, corner faster and accelerate harder. So, for high HP cars, it usually results in lower lap-times/ETs. Aero devices do indeed make set-up more complicated.

    How to get downforce on 2001 GTS?

    Sonny hit it right on, by real cars I mean those without super stiff race suspension. Like I said, this is kind of a hard question to address via messaging. Ground effects is a pretty efficient (lots of downforce for minimal drag) way to get downforce, which is why it is used at the top levels...

    How to get downforce on 2001 GTS?

    I delved rather deeply into this subject, including talking with DC, hiring an aerodynamicist, lots of reading, and, of course, some on track testing. Big downforce generally comes from big aero devices, so there's not a lot to be gained with subtle aids. I would advise you steer clear of...

    "Big Boy" racing seats???

    Re: \"Big Boy\" racing seats??? Im sure most of the respondents mean well, but as another "Big Guy" (6'3", 270 lbs) I can tell you most of their suggestions are a waste of time. I recently went around to shops in the Bay Area and tried out about 2 dozen models from Recaro, Corbeau, Sparco...

    2 people die in Viper in Audi Uphill race

    There is a great deal of speculation and misinformation being posted about this event. I worked corner 2A on Saturday and, having a radio, heard all of the radio traffic between the course workers and event staff as they responded to the incident. I worked corner 16 (where the car went off)...

    BIG RECALL ON ALL VIPERS?

    Viper Wannabe, You need to have any potential purchase checked out by an experienced Tech. As David Jenkins mentions above, none of the stuff mentioned in the recall is "news". My 2002 GTS had its 200 mile service just before the recall was published, however, my Tech (Ted May) was fully...

    Hood up versus hood down RWHP question

    The stock Viper intake grabs a lot of air from under the hood. I've heard that every 10 degree increase in intake temperature results in a 1% loss in HP. Does anybody have any real world data on this? For example, dyno pulls with the hood up versus with the hood down?

    Moving to SF bay area - bring the Viper??

    California only gives you 10 days to register (and smog) your car.

    Moving to SF bay area - bring the Viper??

    Agonizing? You're kidding, right? Cost-wise, Silicon Valley is a breed apart, so be prepared for a little slipping down the financial food-chain. If you get over that (many don't) you'll want to have your car with you. P.S. How come none of the locals has mentioned Alice's, or Skyline, or...

    Questions on new air filter setup

    USAF BAD ASP, The stock airbox, even with smooth tubes, gets quite a bit of air from under the hood, because the NACA duct's size and placement just can't handle 8 liters (even at speed). Even the air that does come through the NACA duct gets heated as it passes through the box (the box isn't...

    Warped Stoptech rotors. Part 2....

    Bedding not only prepares the pad, but also prepares the rotor surface, by "cooking" on a thin film of pad material. So, including bedding instructions is not so strange.

    Does anybody know if a sequential shifter kit is available for the Viper?

    Seat Lowering Kit Question

    DG, If you don't like the way you fit, just reinstall a set of stock seat rails.

    Ok, so i finally drove a GTS and here is what i found..

    The Viper is the automotive equivalent of a Harley. For those who get it, no explanation is necessary. For those who don't get it, no explanation will suffice.

    Where can I get a driver/passanger intercom...

    I'd recommend you go with Peltor rather than the motorcycle stuff. All the rally guys use it as they have stuff specifically designed for use in race cars. You can get just headsets or they also sell SA2000 helmets with earpieces and mic's already built in.

    Seat Lowering Kit Question

    The install is moderately difficult and results in the seat being 2" lower (front and rear) and bolted into the rearmost fore/aft position. Investigate seating options carefully before making your purchase. I bought the kit and it didn't work for me. NWE was very good about accepting the...

    Tall guy seats?

    Seat update. I tried (and ordered) the Sparco Roadster this weekend. It fits in the car and lowers you about as much as removing the underseat webbing and installing the NWE 2" kit. This puts your butt about 2.5" above the floor. Since I first posted, I've tried at least 2 dozen seats. The...

    Viper picture in top view

    I'm meeting with an aerodynamicist next week to discuss Viper aerodynamics. He asked for a picture of the car in plan view (looking straight down on top of the car). Does anybody have one they could email or fax me? [email protected] FX: 650.559.7708

    Selling the Vette getting a Viper

    Buy from Bill. You won't beat his price and nobody is better to deal with. John, from Viper transport (that's how you'll get it), is also very accomodating. Woodhouse gives back a lot to the Viper community, so if anybody "deserves" the business, it's Woodhouse. I bought a Graphite 02, GTS...

    Tall guy seats?

    I'm looking for helmet clearance in my 2002 GTS. I thought I had the problem licked when I installed the NWE 2" kit and removed the under seat webbing. Unfortunately, I discovered this leaves me sitting on the seat back adjusters. Not very comfortable. I'm now thinking of going to Sparco...

    5 point belts or 6 points????

    I would recommend the 5 point, with the crotch strap running through a hole in the seat. I know that's a pain, and makes it more expensive to install, but that's where the strap needs to go to do its job properly. That is, keep the lap belt down on your hip bones as the shoulder belts try and...
