If you've invested more than 5 minutes driving associated with a Subaru BRZ or Scion FR-S, you probably have got some strong views about the gt86 shifter . While the particular Aisin 6-speed gearbox during these cars is definitely actually pretty good from the factory, there's a typical feeling among proprietors that it could end up being just a little bit better. It's got that mechanical soul we all love, but following a few thousand mls, things can begin to feel a little bit vague, or maybe just not as "clicky" as you'd need for a devoted sports car.
The good thing is that the particular aftermarket for the vehicles is absolutely enormous. You can proceed from a slightly mushy stock setup to a bolt-action rifle feel with just a few option mods. Whether you're searching for a cheaper repair or a complete overhaul, let's break straight down how to get that shifting encounter dialed in specifically how you would like this.
The First Step: Shifter Bushings
If you're on a budget but want to eliminate that rubbery sensation when you're rowing through the things, you need to look from the bushings. The particular stock gt86 shifter assembly uses a lot of soft rubber to maintain noise, vibration, plus harshness (NVH) straight down. That's perfect for the commuter car, but it's the foe of precision.
The most popular mod here is the rear shifter bushing. Most individuals opt for something such as the Whiteline or Perrin polyurethane inserts. It's a little item of plastic-looking stuff, but man, it makes a difference. By replacing that gentle rubber mount from the back associated with the shifter stay with a hard poly bushing, a person stop the entire assembly from flexing whenever you're jamming it into gear. It makes the entrance feel much more defined. You won't be searching regarding third gear mainly because much because the particular shifter actually remains where it's expected to be.
Why a Brief Throw Shifter Changes Everything
In case bushings aren't enough to suit your needs, it's period to discuss a full short throw gt86 shifter kit. Now, you can find two ways to go relating to this: the traditional drop-in style and the more extreme chassis-mounted options.
A regular short throw package, like the types from Kartboy or Cusco, usually works by changing the pivot point geometry. This reduces the distance your hand has in order to move between things by about 25% to 40%. It's a night-and-day distinction. Suddenly, you aren't moving your entire arm to obtain into fifth; it's just a quick flick of the wrist. The downside? This will require the bit more hard work to push directly into gear because you're losing some influence. Most people discover the trade-off completely worth it for the "notchy" feel.
Going Pro along with Chassis-Mounted Shifters
Then you have the big guns—brands like IRP or even Billetworkz. These aren't just your typical gt86 shifter upgrades; these are total mechanical overhauls. In contrast to the stock shifter that sits within a cradle attached to the transmission, these bolt directly in order to the chassis.
The shifter becomes a tall, top to bottom tower that sits much closer in order to the steering wheel. This particular is huge for track driving or even spirited mountain operates because your hand doesn't have in order to travel definately not the particular wheel to the shifter. Plus, they appear incredibly cool plus purposeful. You need to be aware: because they are bolted to the car's frame, you're going to hear and feel everything the transmission is doing. It's loud, this rattles a little bit, and it's very raw. For a daily driver, this might be the bit much, yet for a weekend toy, it's the particular peak experience.
Don't Overlook the particular Shift Knob
It sounds simple, probably even a bit cosmetic, however the weight of your shift knob plays a massive function in the way the gt86 shifter thinks in your hands. Most stock pulls are fairly light, which is fine, yet a weighted knob can act like a counterweight.
When you have a heavier knob—something in the 400g to 600g range—the masse helps "throw" the shifter into the next gear. It smooths out several of that notchiness that people complain about with the particular GT86 transmission, specifically when the car is cold. On the flip part, some purists choose a super light teardrop-style knob mainly because it gives a person more "feedback" by means of your palm. It's all about individual preference, but if your shifts feel a bit clunky, trying a heavier knob is an easy, five-minute fix.
Addressing the particular "Crunchy" Second Gear
We can't talk about the gt86 shifter with no mentioning the notorious cold-start crunch. In the event that you live somewhere even remotely cold, you know the particular struggle of trying to get the vehicle into second gear for the very first ten minutes associated with your drive. This feels like you're trying to stir a bucket associated with gravel.
Whilst a much better shifter helps, this is often a fluid concern. Lots of owners claim by swapping the particular factory transmission fluid for something like Motul Gear 300 or Red Line MT-90. While it doesn't physically change the shifter itself, it makes the synchros much happier. When the internal components move smoother, the particular gt86 shifter feels a great deal more cooperative. It's one of those "maintenance as a good upgrade" issues that really pays off over time.
Transmission Brackets and Inserts
If you've performed the bushings as well as the shifter itself so you still feel such as the gearbox will be moving around too significantly under hard velocity, you might desire to look at the transmitting mount.
The transmission within the GT86 will be held in location by a fairly soft mount. When you're driving hard, the whole transmission can twist slightly. This "twist" throws off the alignment of the shift linkage, making it harder to find gears. Adding a stiffening insert into the transmission support helps keep every thing lined up. It's a cheap part, but it adds a bit of stoß to the cabin. Again, it's all regarding where you want to draw the collection between "race car" and "comfortable cruiser. "
Locating Your Perfect Set up
There isn't an one-size-fits-all reply for that perfect gt86 shifter setup. It really depends on what you do with the car.
- With regard to the Daily Driver: Stick with a weighted shift knob, a rear shifter bushing, and maybe a few better fluid. This keeps the vehicle quiet and simple in order to drive but tightens up the slack.
- With regard to the Canyon Carver: Add a quality short-throw shifter into the mix. You'll enjoy the precision when you're downshifting in to a tight part.
- For your Track Rat: Go regarding the chassis-mounted shifter and stiff supports. The noise won't matter when you're within a helmet, and the lightning-fast adjustments will shave period off your laps.
The attractiveness of the GT86 platform is the fact that it's essentially a LEGO set for vehicle enthusiasts. You can begin little and keep adding bits until the gt86 shifter feels exactly the way you dreamed of it should when you initially bought the car. It's one of the most tactile parts of the generating experience, so it's worth spending a little time and money to obtain it right. After all, you're coming in contact with it every several seconds—might as well create sure it feels great.
