SURE’s CounterShift Weight Replacement for MS3

Sunday, August 22, 2010 @ 12:08 AM

Today I received my new SURE Motorsports 2010 Mazdaspeed 3 CounterShift weight replacement. Now many of you may be asking… “Why replace the counter-shift weight, what is it anyway?”. The theory behind this simple little weight is that the heavier it is the smoother the shifting. Although this is true it can make the shifting sluggish. Some of you may not even notice that your shifting is sluggish. However, being that I have had a short-shifter installed into every one of my cars up until now, I notice!  By removing the stock weight the shifter will move much faster but will be a lot more harsh and clunky through shifts between 1st and 6th. Being clunky can cause you to miss a gear and that is never good in the quarter mile!  So SURE Motorsports has created a nice “in between” which will add shifting speed while remaining smooth through the gears.

Below is how to replace the Stock 2010 Mazdaspeed 3 counter-shift weight with the SURE Motorsports Mazdaspeed 3 CounterShift weight and here is the product review for SURE Motorsports’ CounterShift weight.

Where is it:

The counter-shift weight is found under the (1) stock or (2) aftermarket air intake. Yes you must remove the intake to get to this part.

Tools Needed:

  • 12 mm wrench or socket wrench
  • phillips head screwdriver
  • needle nose pliers
  • Gloves

What to do:

Remove the shock Air box [10mm socket wrench, phillips head screwdriver, needle nose pliers]. (1) Remove screw, loosen fan Pipe. (2) Detach sensor and loosen Clamp. (3) Detach sensor wire mount with needle nose pliers. (4) Pull up and out! (5) If you want you can remove the rubber intake hose [loosen clamps and pull], however, you can still easily get to the counter-shift weight regardless.

Loosen the screws on the top of the bar [12mm wrench]. (1) Be firm but gentle so you do not put too much pressure on the shifting linkage. (2) Here you can see the difference in size between the SURE Motorsports CounterShift weight [top] and the Mazdaspeed 3 stock counter-shift weight [bottom]. (3) Use the same stock screws and bolt the SURE Motorsports CounterShift weight right back on.
