The stock driveshaft is replaced with a 1-piece aluminum driveshaft rated at 1000ft-lbs of torque standard in the “R” package. Two other driveshaft options are available: a 1-piece carbon fiber driveshaft or a 2-piece Alcoa 7 driveshaft. The carbon fiber is rated at 1000ft-lbs of torque just like the standard aluminum one, but it weighs less. The Alcoa 7 driveshaft is a 2-piece design just like the stock one, so it allows the same driveline angles as originally intended by the engineers. It is also much stronger, and it is not only rated at 1500ft-lbs of torque, every single one is torque tested to 1500ft-lbs and certified before it goes on your car. The Alcoa 7 option is hands down the best option with the only downside being the added cost.

The stock rear upper and lower control arms and end links are replaced with chromoly arms with Delrin bushings standard in the “R” package. These get upgraded because the stock arms are very weak and have excessive deflection under hard acceleration. This is where “wheel-hop” starts and leads to broken axles, differentials, driveshafts, etc. You have the option of going with fully adjustable billet upper and lower control arms, toe links and end links with spherical and hybrid bushings. These are the strongest control arms available and since they are fully adjustable, they ensure perfect alignment under any conditions. If the car is going to be lowered for a more aggressive stance and better handling these solve any alignment issues. If your planning on spending most of your time at the drag strip these arms allow for positive rear camber so when the rear end squats while launching the tire’s contact patch can be perfectly aligned with the ground for the most traction. These arms are also required if you are going with our 15” rear wheel conversion since they are designed to fit inside a 15” wheel with zero grinding and cutting when paired with our billet rear spindles. The front upper control arms can also be replaced with much stronger, fully adjustable billet control arms with spherical bushings.

Fully Adjustable Billet Front Control Arms (+$1,350.00)
Fully Adjustable Billet Rear Control Arms (+$1,450.00)
Fully Adjustable Billet Rear Control Arms (Front & Rear) (+$2,800.00)
The Stage 4R is our most reliable build. It also allows a lot of upgrade options that some of the other packages may not offer.
