Subaru Shifter FAQ

I’ve been asked about shifter upgrades a few times lately and decided to post something here. This is the first draft.

Here is a diagram of the shifter:

shifty_742a

The “shifter bushings” you always see advertised are the parts that replace parts D and E. They are on either end of the rod that attaches between the transmission and chassis and holds the base of the shifter in place. Since this goes between the drivetrain that moves around and makes noise there needs to be a bushing there to absorb nvh and allow drivetrain movement. Putting in stiffer parts like the kartboy front bushing reduces the amount of bushing deflection you get while selecting a gear. So forward and back movement gets a much more direct feeling because the stock squishy bushing isn’t moving back while you try to move the shifter forward. With these bushings you actually get some feedback out of the shifter and can feel the syncronizers and dogs engage. Some people call this “notchy” like that is a bad thing. IMO it is how the shifter should feel.

For side to side shifter motion, the u-joint linkage comes into play (parts A on the diagram). The bushings wear out and suddenly the stick has to move a long way to either side before anything in the transmission goes anywhere. Here is the linkage:

There are a couple of different variants of this linkage. Early ones have an external centering spring, some are riveted together, and some use different sized bushings. For later cars where things bolt together you can just buy the bushings for like $20. For older cars with a riveted linkage but without an external return spring you can buy the updated linkage, or drill out the rivet, replace the bushings, and put it back together with a bolt. For older cars with an external spring you have to drill it apart and replace the bushings yourself. I picked up some 3/8″ nylon bushings from mcmaster carr plus a stock linkage bolt. Had to ream the bushings out slightly to 10mm but it works pretty well.

Drilling out the linkage:

The bushings (you need 4) and new bolt:

Super Lap Battle Predictions

Since Daniel O’Donnell (driver of the Professional Awesome EVO) already wrote a preview article about Superlap battle for motoiq, I figured it was kind of pointless to do my own halfassed version of the same thing. Instead I’m going to make my own lap time predictions based off previous times and pure guesswork.

Buttonwillow CW13 sub-50 club

It used to be that going faster than 2:00 was REALLY fast at buttonwillow CW13. It’s still an impressive benchmark, but there are more and more cars that will do that off the lot. I recall a stock GTR going 1:55 a couple years ago at the hands of Billy Johnson, so now I have arbitrarily set the benchmark at 1:50, and thanks to my new database of laptimes, it’s easy to figure out.

Since the first Superlap in 2004 only 28 cars have gone faster than 1:50. Here they are:

01 – 1:37.520 – Billy Johnson – FXMD NSX – U-RWD – Extremespeed 12/8/13
02 – 1:41.046 – David Empringham – Sierra Sierra EVO – U-AWD – SLB 2010
03 – 1:43.523 - Nobuteru Taniguchi – HKS EVO – U-AWD – SLB 2007
04 – 1:44.372 - Tarzan Yamada – Cusco/Tomei STI – U-AWD – SLB 2008
05 – 1:44.586 - Jeff Westphal – GST Impreza – U-AWD – SLB 2010
06 – 1:45.552 - Tarzan Yamada – Crawford STI – U-AWD – SLB 2009
07 – 1:46.736 - Chris Rado – World FWD Scion 1.0 – U-FWD – RTA 2010
08 – 1:46.829 - Paul Gerrard – AMS EVOX – U-AWD – SLB 2009
09 – 1:46.893 - Tyler McQuarrie – C-West S2000 – U-RWD – SLB 2008
10 – 1:47.394 - Chris Rado – World FWD Scion 2.0 – U-FWD – SLB 2011

Willow Springs top 40 time attack cars

So due to popular demand I made this list longer, and updated it with the results from recent Shift-Sector/GTA and Redline events. I suppose one of these days I could go through some nasa or other events but due to the big rules differences and number of events that will be a little difficult. So for now it’s just time attack.

01 – 1:18.555 – Billy Johnson – FXMD NSX – U-RWD – RTA 2009
02 – 1:19.317 – Jeff Westphal – GST Impreza – U-AWD – GTA 2011
03 – 1:20.454 – Jonathan Bomarito – SSE EVO – U-AWD – RTA 2009
04 – 1:20.838 – Tyler McQuarrie – C-West S2000 – U-RWD – RTA 2009
05 – 1:22.097 – Tarzan Yamada – Crawford STI – U-AWD – RTA 2009
06 – 1:22.312 – Chris Rado – World Racing Scion – U-FWD – GTA 2011
07 – 1:22.591 – Russ Warr – LIC Motorsports STi – U-AWD – Subiefest 2009
08 – 1:22.648 – Eric Ovlatt – HRGruppe GT3RS – U-RWD – GTA 2013
09 – 1:22.744 – Joe Scarallo – Group A GTO – U-RWD – CB 2011

Super Lap Battle 2012 Preview

Superlap is only a few weeks away and is shaping up to be a good one. From what I am hearing the turnout will be very good with the potential for new records in every class. The car with the best chance of setting a new overall record and going into the 1:39s is the current record holder, the Factor X Motorsports Development NSX:
