Subaru never brought an STi Type RA-R to the States. With the US finally getting the S209, the Type RA-R is one of the only special editions we never got. My goal for this car is to replicate a Type RA-R with using as many STi and Group N parts I can with a few other upgrades as well.

What are your suspension plans?
Trying to decide what I want to do with mine... |

I want to keep this car as OEM+ as possible. I plan to basically go with all of the STi performance parts and JDM parts I can get. A lot of S208/s209 parts.
I have been approached by a few other Subaru enthusiasts since I got the car and everyone treats this thing like royalty. I feel like adding afermarket parts would make it not so special. However, this thing needs a rear swaybar bad |

The RA and 2019+ also has a different knock sensor and knock detection strategy. Comparing stage 1 2017 vs stage 1 2019 (same as 2018 RA) you do see the newer engine making more power too. There are just a lot of little changes that were made for the RA and 2019 that I think add up to a bit better reliability and power. Take it for what it's worth; my speculation based on observations and no long term data. Conversely, the RA and 2019 STi seem to be running out of fuel sooner. So you can't make as much power once you start down the mod list with stock fueling. Difference aren't huge, but they are there. |

Not completely stock, just lightly modded for reliability. Or so I thought. AOS, stumble fix, downpipe with an e-tune from Torqued Performance. Car isn't my DD so very low mileage, and not abused. Rarely even took it out of "i" mode, which on my tune, was just wastegate boost. Ran Motul 5W-40 since the first oil change and changed every 3,000 miles. Basically I took every precaution I knew to keep it reliable. Failure became evident after running errands all afternoon under just normal driving conditions. No crazy pulls or launches or anything. Sorry, OP, didn't mean to hijack your thread. Congrats on the car! It's beautiful and I hope you enjoy it for years to come. |

And don't worry about the failures of "lightly modified for reliabilty" 2017s... |

Sorry for pseudo venting in this thread. Only reason I commented was because I bought my car with the exact same "OEM+" intentions as OP. I'm pretty sure I'm in the unlucky minority that have had freak failures like mine. My last Subaru was a stock block WRX that I beat the heck out of and it took it like a champ. Still trying to figure out exactly what failed and how with my STi. Oh well, the joy of Subaru ownership

Travis at Snail Performance tunes mine right away though because in California we have 91 octane and the tune for the RA was setup for 93. The stock map doesn't like 91, so the tune I had was for saftey. Also did an IAG AOS right away for saftey as well. |

I haven't found this car needs a rear swaybar yet after autoxing it a few times. It rotates well enough, but I think sticky RE71rs helped a lot with that. |

I'd do the same if I had an RA. Mostly stock (maybe catback, suspension and wheels, etc), that's how they'll keep their value and appeal... unless you don't care about any of that, then go for the send. By the way, here's some info/numbers on the RA/2019 stock block: https://forums.nasioc.com/forums/showthread.php?t=2892143 Long term at such power levels? We shall see. But pretty sure they'll be fine at stock powers.... Last edited by F1EA; 05-12-2019 at 08:44 PM. |

What size rear bar do these have now? I saw they upgraded the rear bar on the S209 to a 20mm.
Also, any plans for a harness? |

I wonder why they reduced the size of the rear bar

I've always wondered that myself. Back in my S2000 track days, I vividly remember mixing and matching various year OEM parts to get the desired suspension setup. Spring rates, both front and rear, changed almost every year on those cars. At one point, I had different strut/spring combinations from different years on my car just to get it to feel how I liked it. In later years, they took a lot of the "snappiness" out of it, which caused understeer. It wasn't uncommon to take a sway bar from an older S2000 and put it on a newer one.

I think as time progresses, manufacturers try to make the ride more comfortable for daily driving (softer suspension, more sound deadening, etc.). I think Subaru has done a nice job with balancing the 18+ STI in terms of a sporty suspension that's comfortable enough for daily driving. Subaru seems to always error on the side of caution and lean more towards understeer, both with their alignment and rear sway bar size. I'm sure this is partially for safety and preventing accidents. I read a lot of stories of people crashing earlier model AP1 S2000s due to the snap oversteer. FWIW, the rear sway bar size was reduced by 1mm at the same time that the struts/springs were revised, the wheels went up to 19" and the fully electronic DCCD (probably not related). |

Congrats! If this is the one that was recently for sale at Jones in Maryland, I semi-seriously contemplated trading in my WRX for it. A great looking ride - hope you enjoy it!
Of course, I'd probably would have had to sleep on the couch for a week for bringing home a car that my wife couldn't drive. And I'd have put too many miles on it anyway (my 2018 WRX already has close to 18k on it). |

Yes a clutch type would solve most of that problem. Expensive solution though.
