This page is dedicated to the upgrades that we have developed to correct production issues on existing Unique Performance vehicles.

G.T. 500E and G.T. 350 SR

Suspension & Steering Upgrades

1. Front Suspension Upgrades
   • The design of the UP front upper control arms contact the springs when unloaded and will contact the inside lip of the front rims while driving. We have developed a procedure to correct these issues and by doing so improve the camber curve of the front suspension during cornering.
     
     
2. Rear torque arm drop bracket
   • We have found that many of these vehicles have driveline vibrations when driving at highways speeds. This is due to incorrect driveline angles between the engine/transmission and the rear axle. We have developed a new design bracket for the rear torque arm that allows more adjustment of the pinion angle to minimize this vibration
3. Rear Suspension Binding & rocker flip
   • We have experienced on these vehicles that the design of the UP rear suspension issues that cause undue stress on the rear suspension components. We have seen rockers inverting causing the suspension to collapse, bent and broken rear shocks, mounting brackets coming loose from the suspension cage, and premature wear on the rocker bearings and heim joints requiring replacement as low as 300 miles. We assess the suspension on each vehicle we service to determine the best course to correct the suspension geometry and replace the damaged components with upgraded units that increase durability, ride quality, and allow the suspension to function without undue stress on these components.
     
     
     
4. Weld Steering Spacers
   • The front steering center link utilizes two small spacers to give clearance for the inner tie rods. These spacers have been known to work loose in the center link and eventually cause failure of the inner tie rod. To correct this issue we weld the spacers to the center link and re powdercoat the part.
     
     
5. Power Steering Cooler
   • Vehicles equipped with the Concept One pulley system and the TCP power steering rack typically experience excessive noise and lack of steering assist. This is caused by aeration of the power steering fluid due to overheating. We correct this with the installation of a power steering cooler and a high quality synthetic power steering fluid.
6. Correct Alignment
   • These vehicles experience a myriad of suspension issues that can be attributed to poor alignment. We have the alignment specifications to correct this.
7. Rear wheels contacting Frame rails when turning into a driveway
   • Due to a mismatch in the rear axle width and tire offset the rear tires on almost all of these vehicles contact the inside of the wheelhouse or frame rail when turning and going over an incline. Unfortunately, short of replacing the rear axle housing and axles or the rear rims the only way to correct this is to install wheel spacers and some require longer wheel studs to accommodate the spacers. This contact is particularly dangerous when mixed with protruding self tapping sheet metal screws into the wheel house as shown in the second picture.
     
     

Engine control, Fuel system, electrical system

1. XFI Upgrade
   • Until the middle of 2007 all of the fuel injected Mustangs utilized a bank fire injection system. Our F.A.S.T. XFI sequential fuel injection upgrade is a must for any owner that bought this vehicle to drive. This system gives improved throttle response, drivability, and fuel efficiency.
     
     
2. Fuel System Upgrades
   • We have found that many of the vehicles were built with fuel systems that are not adequate for the once the vehicles are properly tuned and all of their systems are working properly. Until early 2007 the UP cars were plumbed with the fuel pressure regulator in the rear of the vehicle. Not only does this cause a delay in the fuel pressure increase required for wide open throttle but also causes a surging in the fuel pressure that affects drivability. For a visual demonstration of this observe the twitching in the fuel pressure gauge mounted on the front of the fuel rail while idling. In most cases we replumb the fuel system to handle the higher volume and relocated the fuel pressure regulator as close to the engine as possible to correct these issues.
     
     
3. Charging system upgrades
   • While investigating the high number of alternator failures we discovered that the electrical load of these vehicles exceeded the output of the original alternator. In addition, many of these vehicles were built with an incorrect alternator pulley ratio further straining the electrical system issues.
     
     

Clutch Upgrades

1. Streetable clutch
   • The original clutch selected for these cars during the build was a racing style puck clutch that is not street friendly. We have seen heavy flywheel and pressure plate wear requiring replacement as low as 1000 miles from street use. Our replacement disk is a Kevlar / Aluminum hybrid with a full face on one side and pucks on the other for high performance with streetability.
2. Clutch hydraulics
   • We have an upgraded clutch hydraulic system that is built with OEM durability and clutch pedal feel. A must for any cable clutch car and recommended as an upgrade for existing hydraulic clutch built prior to mid 2007 cars due to a high occurrence of clutch slave leakage. These pictures show a custom installation performed on a T56 6 speed.
     
     

Brake System Upgrades

1. Functional parking brake system
   • Our dual cable parking brake upgrade works. Enough said.
2. Electric hydroboost
   • We have developed an Electric Hydroboost Brake Assist upgrade for the Unique Performance Vehicles that augment the Shelby/Baer brake system and provide a significant increase in stopping power with decreased pedal effort. This upgrade is a must for anyone who wants to drive their performance vehicle on the street.

Super Snakes

1. We have dedicated a large amount of time making the Super Snake as lethal as its reputation. We have developed an upgrade package addressing just about every aspect of the engine and its accessories to allow it to perform as advertised. Our retrofitted Super Snakes are registering close to 600 hp and 600 ft lbs of torque at the wheels and do not overheat in 105* Texas weather in stop & go traffic. When combined with the other upgrades outlined your Super Snake can become a streetable 750 horsepower muscle car. As impressive as these improvements are we are still not satisfied. We have developed a sequential fuel injection system for use on the supercharged FE and are in the works of a 3” exhaust system upgrade, and an intercooler system; all of which will greatly improve horsepower, driveablity, and engine efficiency.
   
   
2. Early build Super Snake engines require additional internal upgrades. Excessive compression ratios have caused internal damage ranging from blown head gaskets to cracked cylinder heads. These engines require a complete engine rebuild with lower compression pistons in addition to our upgrade package. Other internal engine issues we have noted include rocker arm failure and pushrod failure which will be addressed with the engine rebuild.
   
   

Cooling System Upgrades

1. We have worked very closely with our radiator supplier “Be Cool Radiators” to develop cooling system upgrades for all of the UP Shelby Models. We have developed a cooling system capable of over 1000 horsepower for our new build cars, a direct bolt in retrofit radiator with integrated fan for the Super Snakes and an upgrade for the Small block engine Performance Models capable of cooling up to 700 horsepower. These upgraded radiators also allow additional hood clearance for the UP billet radiator cap cover installed on many vehicles.

Body Upgrades

1. Early versions of the Super Snake center consoles used an aluminum laminate over the belly pan of the console that will bubble when exposed to the summer heat. We have an upgraded full aluminum belly pan available as an upgrade. This center console has become a popular upgrade for Performance model GT500Es as well.
   
   
2. Not only is the factory strut tower brace on these vehicles non functional, but will even cause damage to the cowl and the hood if adjusted properly to support the strut towers. Our upgraded strut tower brace shown in the second picture integrates bracing from the cowl lip into the firewall giving the reinforcement needed to function as intended. We have also relocated the strut bar mounts so they will never cause paint damage to the bottom side of your hood.
   
   
3. This picture shows the standard UP way of mounting and wiring the Nitrous Switch. We clean up this hole in the floor and use a box to enclose the switch and wiring.
   

Sheet metal and Body

1. One of the most difficult areas to address on these vehicles is the sheet metal and body. Many of you have already experienced issues with cracks, rust, and paint defects such as pinholes, blisters, shrinkage, hazing, overspray, hard tape lines, and just general poor finish quality. These pictures show some of the issues you are experiencing that sometimes can only be addressed by sanding down to the primer and starting again. This sometimes requires repainting the entire vehicle to be sure that the problems do not resurface. We are currently working with a partner shop that specializes in high end body restorations that can handle any level of sheet metal or body repair needed and deliver a high quality final product on these cars or any type of vehicle.

Foose Camaro

1. Camaro experienced the same issues with engine drivability resulting from poor tuning.
2. Early Camaro utilized an oval throttle body and a throttle linkage that had a tendency to bind while driving.
3. These same oval throttle body engines utilized an open air filter mounted directly to the throttle body drawing hot air into the engine. Later vehicles were equipped with the cold air system as shown in the picture above.
4. The exhaust routing on the Camaro often caused interference issues between the subfame bracing, the floors, and the rear suspension. The 572 engine is restricted by the 2 ½” exhaust system and benefits from upgrading to 3”.
5. Camaro also experienced the same “race car” clutch ailments and benefits from upgraded clutch hydraulics and a more streetable clutch.
6. Camaro also had the fuel pressure regulator plumbed in the rear of the fuel system that needs to be relocated.
7. Late Camaro hoods experienced a warpage issue from engine heat. The only solution to this is to replace the hood with one from the original vendor that did not suffer from this issue.

Foose Challenger

1. There were only two Challengers completed. One was the Yellow/Black prototype car that became the Good Guys giveaway car and the second was the Green/Black first production car that was sold at Barrett Jackson in January of 2007.
