Motegi Racing's Killer AE86 Corolla GTS
By Mike Kojima
The Iconic Toyota Corolla AE86 is one of our all time favorite cars. The last of the RWD econoboxes, the AE86 had timeless styling which still looks good today 26 years after it was first created. The rare GTS variant had the then radical 4AG engine which had an unheard of for its time, 4 valves per cylinder and dual overhead cams with a 7500 rpm redline. Its 1600cc's pumped out 114 hp at a time when your typical econo car revved to around 6000 rpm and put out 80 something hp.
 |
| An old school car like an AE86 is a flexi flyer by today's standards and the chassis needs to be stiffened up to get decent handling with modern suspension and tires. An all inclusive cage ties the entire unibody together for both stiffness and safety. |
The GTS also had 4 wheel disc brakes, a 5-speed manual transmission, 4.30 gears and a limited slip differential, all radical performance features in the day. The GTS was bound to be a cult car from the day it was created. Fast forward many years later when the drift craze started to sweep the world and the anime cartoon "Initial D" became popular. Its hero drove an AE86 which hardened the car's cult favorite status.
 |
| The cage ties into the shock mounts in the rear. The pyramid like structure in the center of the rear of the car is for stiffness, side impact protection and a mounting place for the trick rear suspension. |
These factors made the AE86 a prized car and nice examples are now collector’s items. I myself had an AE86 that was fully equipped with all of the TRD N1 parts made. I am now kicking myself for selling it. Thus I have a soft spot in my heart for the AE86 and one day I will own another one. When I heard the Motegi Racing was building a killer AE86 in collaboration with Papadakis Racing, I had to go and take a look at the finished product.

| At the center of this rear structure is the mounting location for the third torque arm of the three link rear suspension. The factory 4 link has a lot of bind and toe steer. It also has so much antisquat that the car wheel hops and wants to squirt sideways under throttle. The three link eliminates a lot of this. |

| The spare tire well has been covered by this nice bead rolled plate with a fuel cell underneath. |

Oooh thanks Mike and Jeff! Ive seen this at a couple of recent events, and its the only AE86 ive ever fallen in love with. Sweet feature!

This may sound Speed Hunters-ish but I've never liked the wheel fitment on this car. I'm not sure why and I'm not a Hellla Flush fan so that's not it. I think maybe the lip is just too wide on it.

I normally don't care about the appearance of a race car, but that aero work is HOT.

I used to own a first gen Integra and since then I've always loved boxy 80's coupes with pop-up headlights. I'd love an AE86 and this one is very well done. and kudos to Motegi for building a show car with balls. Can't wait to see this car in action.
Thursday, April 14, 2011 9:14 AM
Love the IMSA look. Kono did a great job on this one!
Thursday, April 14, 2011 9:55 AM
Epic timing! A friend of mine is currently building an AE86 for drift, it's ready for the cage and the suspension mods right now.
Thursday, April 14, 2011 10:26 AM
Absolute yes. I love how this article has come up right around when I've decided to leave my Impreza as a DD for now, and finally get focused around my '84 SR5 hatch! I'd love to know where they got the 3 link setup (I imagine it is a custom engineered setup, but I could obviously be quite wrong). I'm planning on going inexpensive, but functional for now (being effectively all T3 parts) with my suspension, rebuilding the GT-S rear end that I have, and building a decent smallport out of an FX16, maybe with some blacktop ITB's if I can find 'em. Wish I could get my hands on an IS200 3S-GE... I want to turbocharge one so bad!

Such a soft spot for the AEs! I think I'm looking for clean examples probably once a month, minimum. Scott kind of asked this, but Mike how would you go about tuning the original suspension for, let's say, road race without having to go to a custom three link? You had me extremely fascinated about the thought of this Hachi in MPTCC. Would its power-to-weight make the TU cut though?
Thursday, April 14, 2011 11:12 AM
The 3 link is a custom part but its pretty easy to engineer. It reduces a lot of the stupid toe steer of the rear and for sure eliminates the bind. Whiteline makes a kit to relocate the stock rear links to reduce the anti in case you want something that bolts in. To really fix it requires a lot of fabrication. When I was at TRD we used to cut a hole in the floor. make new mounts and use the another pair of lower links to replace the short and steeply angled upper links. I think an AE86 would work well in TU class.

Mike, any idea on spring rates that this car runs? Like I said a friend is building an AE86 at the moment. Supercharged VQ30 engine!
Thursday, April 14, 2011 11:26 AM
Hi Bob, I have no idea but this car hasn't been sorted yet so the info would be moot anyway. At TRD with our N1 spec track day stuff we used to run 4.5 kg front and 4.5-3.9 kg in the rear but that was a long time ago with much lamer tires. With the heavier VQ I would do something like 8kg front and 6 kg rear to start. I am mulling over putting an LS, a T56 and a quick change in one. We have one sitting around.
Thursday, April 14, 2011 11:51 AM
why doesn't my engine look like that :cry:
Thursday, April 14, 2011 12:08 PM
Its such a waste to run 225 tires on 9.5 inch wide wheels.
Thursday, April 14, 2011 12:26 PM
I keep thinking it would be cool if some manufacturer made a RWD econobox now. Honda could keep the S2000 going if they spread the platform use to a low powered sedan and coupe for Acura. Mazda good do the same with its MX-5 platform. And Infiniti could bring a intro car below the G37 by putting a 4-banger in a 4dr 370 chassis. Then we could keep all the cheap racing sports pure and available. I'd be willing to split the difference between a Civic and an S2000 in price for a RWD car.
Thursday, April 14, 2011 12:56 PM
Mike, the VQ30 is surprisingly light. I can pick it up and carry it away...I'd guesstimate 200 lbs (no manifolds). It's probably lighter than the 4AGE.
Thursday, April 14, 2011 12:57 PM
Don't worry Mike, we all know 86mm by 86mm gives us 1998cc's! =D

Jasonrg77 - The only one on the horizon is the Scion FT-S, soon to debut. Although Toyota has been teasing us for how many years now with the FT-86, FT-86 II and now the FT-S? I ranted about this and the lack of the affordable new AWD platforms back on the Essa article which turned into the drift debate. Mike - Could we call it "Project AffordabLS Hachi Unlimited"? Please do something crazy fun like this! I love inspirational crazy! I keep thinking somebody needs to try and put together the "affordable" TC rwd conversion. Screw that, LS 86 would have more style.

The cheapest RWD car is probably the Genesis right now, and agree there need to be more of these out there. I assume there just isn't enough of a market for it. We all sit on here and say we'd buy one, but everywhere you look on our streets, is econoboxes that are bland. Hyundai does a great sheep series of commercials that proves this point. Maybe we're all under the impression that people want cars to drive instead of a box to go from A to B. Come one auto makers, make something with a soul. This is why a lot of us drive 20+ year old cars. They still have a soul.

Those rear shocks are 30 series not 2812's. And they need to be shortened.
Thursday, April 14, 2011 4:30 PM
Cheap RWD 2dr. Sports cars need cheap 4dr. sisters. The Genesis is cool, but it needs the sedan to be cheap as well. Subarus can be as cheap as midlevel Civics and Corollas. The thing is nobody likes an NA subaru except nannies and untenured college teachers, and they aren't known for exceptional handling.
Thursday, April 14, 2011 9:09 PM
Pretty much bottomed out....
Thursday, April 14, 2011 10:14 PM
Nice. I was just contemplating the best way to mount a splitter on my car. Those brackets look perfect.
Friday, April 15, 2011 1:05 AM
One of the best (if not the best) looking AE86 in the country.
Friday, April 15, 2011 1:44 AM
Here is another great AE86 from down under (the article sucks, but the pics show quite a bit): http://speedhunters.com/archive/2010/08/06/car-spotlight-gt-gt-beau-yate-s-ae86.aspx
Friday, April 15, 2011 12:32 PM
Jasonrg77 I believe Subaru has been developing a 2.0 NA boxer engine with 200 hp for the FT-86 and the Subaru Variant. I think you are referring to the NA variants they have now anyways. =)
Saturday, April 16, 2011 1:59 PM
Robbie, the tires are 255s, not 225s.
Saturday, April 16, 2011 10:21 PM
The info steff sent me said 225.
Monday, April 25, 2011 9:15 PM
My Hats off to Motegi for sponsoring that Cool AE86. Over the years I’ve seen some pretty trick stuff made for the AE86, the coolest was the SS Works IRS setup. Wish I could get Kono to do the air damn on my race MR2--nice work Davegt27

Hey Mike, can you PM me or e-mail me at some point? I have some questions regarding an AE86 (mine, to be exact) and its suspension, none of which seem to have answers anywhere else. They're some brain ticklers, that much is certain (and far too long and very slightly off-topic for the comment section). I would just post a forum thread, but I'm really only interested in your thoughts on the subject, to be perfectly honest. Your help is greatly appreciated (and may very well speed up the process of a pretty interesting build), Scott

Also, if the meats on those 9.5" wide wheels are 225's, I may very well be a trunk monkey's uncle.
