Common Problems


Common Modifications

Shifter

An aftermarket shifter is one of the first modifications most Cobra owners make.  An aftermarket shifter provides a shorter throw, better shift feel, pre-loads the 2-3 shift to eliminate missed shifts, and provides adjustable positive shift stops to protect the shift forks.  Some people have pointed out that the transmission noise level increases after this modification, but most people agree that it is worth a little extra noise to gain the benefits it provides.  Listed below are some of the popular aftermarket shifters:

B&M Ripper
Hurst
Pro 5.0
Steeda Tri-Ax

Gears

Changing the rear-end gear ratio is one of the most popular modifications. 

Subframe Connectors

Subframe connectors are also a popular modification.  These add strength by connecting the front and rear subframes with a solid piece of round or square tubing.  It is generally accepted that these must be welded on for them to be of any value.  One thing to consider is that subframes are illegal in several SCCA autocross classes (but they are legal in the new Street Modified class).
