OMGHi2U Kost's STI Type-RA 196/500: SCCA Autox Prep

So I finally got back into the serious Subaru game... Purchased a 2018 WRX STI Type-RA last week! Traded in my 2017 GTI on the spot..

I originally placed an order with Huerberger when the Type-RA was first announced. But then the actual equipment and price was announced... Canceled my order after that!

What changed? Well a year later and almost $5000 off MSRP after sitting on the lot for several months changed my mind! Combine that with Subaru's 1.9% apr deal last month, and the deal was too hard to pass up. I did look at the Series.Gray STI that arrived last weekend and was like meh after seeing the color. MSRP on that car was $42,000 which isn't bad at all considering the equipment is almost the same as the Type-RA! The extra ~$3000 for the spoiler, CF roof and gorgeous gold forged wheels was worth it IMO.

Anyhow, I bought this car for several reasons... One being I've always wanted a Type-RA going back to the old GC original models. The 2018 season was a big personal milestone for me, winning my class for the year in the GTI as well as placing 5th overall in the Sacramento region for PAX. With the Type-RA, I plan on testing the car first in B-Street and then decide if its worth the move up to Street Touring Ultra (STU) and throw a few mods at the car.

In any case, here is a quick video I put together with my review of my Type-RA:


For your viewing pleasure, a few photos to start with!






The plan is to keep a log of any mods and any events the car attends in this thread. So stick around, there is much much more to come!

One of the first things I've done with the Type-RA is actually the result of some vigorous testing by Snail Performance with their personal Type-RA. Snail Performance here in California is actually based out of M45 Automotive's shop now, where we have a full roll-on, enclosed Mustang Dynometer room. Snail Performance actually discovered, as some of you may know, that the new 2018 motor in the Type-RA was VERY aggressively tuned by the factory. Works great if you have 93 octane available, but here in CA we only have 91... Best to tune it down a bit.

Surprisingly though, the RA makes MORE power than advertised by quite a bit! Stock the RA's are making around 280whp, more than previous STI's on the same dyno. With the Cobb Accessport tuned by Snail, we saw a HUGE improvement in low-end torque even on a completely stock car!

Sadly if I stay in B-street, I can't use these tunes, which is why having something like an Accessport is handy for Autocross because you can convert back to the stock tune for racing in a stock class. In the future, if the RA does wind up racing in STU, there will be serious gains to be had even with the simple bolt ons allowed in that class. But for now daily driving the car, I plan on using the Snail tunes to prevent premature detonation with the advanced timing of the stock map.

Pics for posterity:





I should have a map comparing the stock tune and Snail pro tune later this week.

So I watched your vid finally, and I enjoyed it. But one point you made that stuck with me was having a harness.

When I was doing AutoX in my 12 WRX the one thing that I always wished I invested in was a harness because I spent a lot of time trying to brace my self.
I am looking forward to seeing your set up once you get a harness installed. I want something safe but not a permanent fixture in the car. I only plan to keep my car in B street. Tires, rear sway, IAG or Perrin AOS and that coolant line mod IAG supplies that you mention in your video.

When you did your pull on the dyno what gear were you in? I keep seeing people claim it does not matter whether the pull is done in 3rd or 4th and then I see some say it does. Every gas station here sells 93 Octane so I will eventually have a pull done on the car to see what it is putting down. I figured the power claims SOA made were badly underrated.

Looking forward to all of your updates.

I installed the harness already. The Rallye harnesses from Schroth are rather easy to install, just have to find the right angle and locations to use. I'll post pics later, and obviously its strictly for track use and autocross not for the street... It stays tucked under the seat when I'm not using it.

A few more pics today....

First of all, a photo of the stock run versus tuned run on the Dyno with the RA. As you can see there was a BIG gain with the tune in the lower RPM's. The minor loss up top was from fixing the excessive timing of the factory tune.



Few cars at M45 Automotive.




Today we had a "Detail your Type-RA" day at M45 Automotive.

Yes, as some of you may have noticed, I've ALREADY purchased a catback for the car!

After a bit of research, I wound up with a single-outlet, single-tip Invidia Q300 exhaust. I went with single tip primarily because of saving some weight, plus it was inexpensive. Build quality is typical Invidia but better because it doesn't have the awkward Y pipe with the dual exhaust Invidia catbacks, and the noise is pretty standard.

I may do an exhaust hole cover for the other side. I also might try other exhaust, there is a SPT catback I can borrow for the car potentially, and I might consider trying a resonator delete for the stock Type-RA exhaust but I'm inclined to leave that alone. The stock exhaust on this car is TOO QUIET! I really couldn't tell where the engine was at RPM wise without staring at the tach or setting the shift beep. Needed some audible indicator for racing.

Now for a couple photos... Its not the best looking exhaust, well the exhaust itself is nice but a lot of folks don't like single exit exhausts. IMO quad tips on a 4-cylider car is excessive but to each their own I guess



Weight savings wasn't as much as I hoped, 12-13lbs. Could have saved more with the Titanium Tomei, but that thing is hideous and noisy as hell.

Took #196 out for its maiden autocross today!



Got a trophy... We do an Enduro at the end of our season here. Its a five lap run and the winner of the day gets a trophy in each class. I was the only one in B-Street today lol

Anyway, the car started off rough... Lots of understeer and the tires were terrible. During the enduro the tires started to wear in a bit and started to adjust to the car. But the stock tires are TERRIBLE for autocross! Needs RE71Rs ASAP.

Tried out track mode and all traction control systems off. Also tried auto diff settings and locking it in full rear. I think I liked everything off plus locked in full rear, but I will have to do more testing to figure out whats the fastest setup.

Here is a vid of the enduro and some fun runs too:

What is allowing you to display the rpms and sensor readouts on your videos? Is that a camera or an app?

Phone App called Trackaddict combined with OBD-II data via bluetooth adapter overlayed via RaceRender with Gopro and Gear360 cameras.

Subaru is so weird when it comes to tires. They're expensive AND crappy. Go figure.

These Advan sports are not crappy per say... Its just they are not competitive. No car manufacturer puts competitive Autox tires on their cars, period.

Even the Cup 2's are not up to snuff.

I dunno. I think some Cup 2's would do quite well except for kicking you up to ASP for the treadwear rating

That 5 run enduro sounds pretty fun. How did they run it? A connecting section between the start/finish? Or just a combination of 5 best runs?

If you smooth out your inputs, particularly turn in and braking I think you'll find a lot less understeer.

Nice choice on the exhaust btw. I've always thought the quad tips seemed excessive for a 300hp car. Especially when it's just a single pipe that splits into 4 for the look

You can see from the video its just a circular course with an entry and exit, plus a flag man signifying final lap and checkered flag.

Ya quad tips on this car is a tad overkill... But I think I'm going to try a different muffler on the piping to see if I can get it to fit better and shave some more weight.

New Autox wheels and tires installed!

Picked up a used set of 08-14 BBS wheels, had them repaired (small bend) and powder coated Gloss Black by Kwicksilver wheel repair here in Sacramento. Turned out pretty good in the looks department.

Only saved 1.5lbs of weight though... But the shorter tires make for quicker gearing which feels quite nice so far. Need to do some more testing, and get a swaybar on the car... Thinking front swaybar right now.

Tires are 255/35r18 RE71R's btw... Love these tires, my third set of them now lol

Vid 1 lap 4 looked very fluid, 5 seemed a bit more forced. Altogether it's great to see someone enjoying their car. The new setup looks good too, a lil meaner in fact.

Any idea what size tire would give the same overall diameter of the stock setup? I want to run a set for daily use with some all seasons. Thinking of picking up a set of conti extreme contact dws tires like i had on the wrx. Best all seasons i have ever driven on.

If i find a set of those oem bbs wheels used im having them painted gold. I just love how gold looks on a white car even if im cleaning them every few days.

Ya, Tire Rack can help with that. They list specs for all their tires including rotational diameter. You can ross reference and figure out what sizes are close to stock diameter there.

I think the tire sizes in your photos need to be updated.

OE tire size on the Type RA is 245/35R19. 25.7" diameter.

255/35R18 will be 25.0".

The closest match to original height is going to be 255/40R18, slightly larger at 26" and available in RE71R, Falken 615k+ and the more daily friendly max performance summer Contin/Michelin's.

The DWS06 is also available in that 255/40R18 size and wants to be mounted on wheels between 8.5" and 10".

First autocross of the year!

The new wheels/tires make the car come alive for autox for sure, so much more fun to drive. Still not as much of a weapon as the GTI was for autox but its getting there.



More vids/pics coming from today...

Have you installed a new front swaybar yet? If so which one and what diameter? How much did it change the driving characteristics?

I did try a front swaybar, had a lot of difficulties with it (long story). When I finally drove it, it drove terrible just added understeer everywhere.

Going to skip a rear swaybar now too as the rear tire is almost lifting at this point.
