Racing Radios Four Conductor DSP Harness w/ Rear Plug
Digital Signal Processing
Four-conductor (IMSA) radio wiring harness with Digital Signal Processing for Motorola mobile radios. Electronically filters out unwanted noise picked up by the driver's microphone.
The ultimate ambient noise canceling in-car harness.
Specifically designed by the engineers at Racing Radios, the DSP harness reduces car to crew communications by -20 dB.
A sound processing chip is installed into the harness that uses precise computer algorithms to determine what is voice and what is engine noise. The result? A driver you can actually understand and hear.
This harness is used by top teams worldwide in every form of racing and this technology can be adapted to almost any application you can think of in two-way voice communications. This harness is designed for use on base station in-car radios. Please call for inquiries or questions.
Features
Plugs directly into the rear 16-pin accessory jack on Motorola mobile radios.
Compatible with CM200, CM300, PM400, M1225 and CDM mobile radios.

Racetech RT4119W Racing Seat
from $2,299.00
Racetech RT4119W Racing Seat
The Racetech RT4119W Racing Seat is based on Racetech's highly successful 119 Series platform, delivering the same exceptional ergonomics, driver support, and patented back-mount technology in a configuration without head restraints. Designed specifically for applications where improved visibility and easier ingress and egress are desired, the RT4119W and RT4119WT are ideal for track-day cars, HPDE vehicles, off-road race trucks, pro-touring builds, and outlaw drag cars.
Derived from the RT4119WHR and RT4119WTHR competition seats, these models retain Racetech's race-proven shell design and unique back-mount system, which provides superior chassis feedback, increased seat stability, and reduced driver fatigue compared to conventional floor-mounted racing seats.
Available in Wide and Wide & Tall configurations, the RT4119W can be further customized with optional low-profile base cushions and side cushions to achieve the ideal fit and support for a wide range of drivers.
Purpose-Built for HPDE and Track-Day Vehicles
By eliminating the integrated head restraints found on FIA-approved competition models, the RT4119W offers improved peripheral visibility and easier access to the cockpit. This makes it particularly popular in street-based track cars, vintage race cars, off-road vehicles, and applications where head restraints may interfere with vehicle operation or driver comfort.
Note: The RT4119W and RT4119WT are not FIA-homologated racing seats and are intended for applications where FIA certification is not required.
Mounting Options
Side Mount Installation: Compatible with Racetech RTB1009M 5mm aluminum side-mount brackets (sold separately).
Back Mount Installation: Compatible with the Racetech RTB2115B shoulder bracket and RTB2005C roll cage clamps.
RTB2115B Bracket: Attaches directly to the seat's shoulder beam to provide additional support and rigidity.
RTB2005C Clamps: Available for 38mm (1.5"), 41mm (1.625"), and 45mm (1.75") roll cage tubing diameters.

Race Technologies Racing Brake Pads
RT RE10 COMPOUND1
RE10 is the ultimate endurance race compound, offering a balance of excellent stopping power, low thermal conductivity, and extremely low pad and rotor wear. Utilizing the latest friction material technology, Race Technologies RE10 offers consistent performance in the most demanding environments.
Typical applications include professional endurance racing, club racing, and HPDE on high braking demand platforms.
RACING PAD NOTES:
Running a "racing use only" pad on the street could produce excessive noise and dust.
Rotor wear could be accelerated if driven at consistently cold temperatures or used in the incorrect temperature range.
Racing pads are designed to work in specific temperature ranges so it's important to choose the right compound for the environment the vehicle will be used in.
Pad compounds are tested on a brake dynamometer over repeated brake applications to test the materials in a controlled environment. Real-world wear rates and temperatures will be influenced by car setup, grip levels, track layout and other variables.
Note 1: "RE" denotes a "racing use only" pad compound.
