Top Speed SSk is the way to go!
I did mine a couple months ago. Got a great price! Installation was simple but time-consuming. Take my word for it:
MAKE SURE YOU MARK THE CABLES BEFORE YOU TAKE THE FACTORY SHIFTER OFF!!
I marked mine in the wrong place so it was like not having it marked. I struggled by having to take everything out, put the cables at 100% rest (or in the middle) and start again. Test it BEFORE you start the car and go. Once you do start the car, engage the car in ALL gears, let clutch out to "biting point" to ensure all gears are good!
It DID TAKE SOME TIME TO GET USED TO "TIGHT" GEARS. So give yourself a week. You will not look back. Even I wondered how I would ever get used to it….now I could not think of getting a Box and NOT ADDING IT, especially for $59!
It DOES IMPROVE your gears shifting times, or times between gears without the engine engaged. In other words, IT IS MUCH QUICKER - LIKE TWICE AS FAST!
Great upgrade….Top Speed's price makes it a no-brainer.
Do it, if you have not already, and you will thank me later.
Think about this too. It is a Shifter Linkage and should be considered a complimentary upgrade to the SSK - didn't say it was FREE! It costs $45 OUCH! PM me if you need the supplier. It takes some of the SLOP out of the shifter cables and ensures the "cheap Factory plastic piece" will not give out when you need it most. It is made of Billet Aluminum and will further "refine" your SSK. It secures tightly around shifter cable.
Most track guys do this mod because a blown shifter CAN RUIN your day! Here's a pic….
