ON November 23rd, SCION dropped off one of its two prototype FR-S vehicles to GReddy Performance Products for a tuning blitz. The goal would be to build a lightly-tuned version of the 2013 Scion FR-S for the US media unveiling taking place just a week later. With limited time, GReddy sought to address the most popular vehicle upgrades. Keeping it simple, wheels, tires, suspension, brakes and exhaust would be the goal for the less-than-a-week transformation. With no off-the-shelf parts available, the scramble was in full swing to complete the prototype development.

WHEELING AND DEALING

You would think that fitting the wheels and tires on the Scion FR-S would be among the easiest of upgrades. Unfortunately, Subaru designed the FR-S with the less popular 5x100mm bolt pattern, instead of the more popular 5x114.3mm bolt pattern. Rather than limit wheel choices to 5x100mm selections, GReddy opted to prototype a hub conversion to open the options to the more popular 5x114.3mm pattern. With this conversion in place, GReddy selected a staggered setup featuring 19x8.5-inch (+45mm) Volk Racing G12s in the front and 19x9.5-inch (+35mm) G12s in the rear. The wheels were fitted with 225/35ZR19 (front) and 245/35ZR19 (rear) Hankook Ventus V12 EVO tires.

S-DROPPED AND C-BALANCED

While the Scion FR-S already features an extremely low center-of-gravity, a properly setup coilover suspension system can drop the FR-S to levels below six-figure supercars while still providing the same ground clearance as these supercars. GReddy’s Type-S coilover system was chosen to lower the FR-S while allowing for proper corner balancing and damper tuning. Adjustable spring perches allow the four corners to be individually adjusted until the proper cross balance, F/R and L/R balances are set. In addition, the Type-S damper features 32-settings that provide balanced compression and rebound damper rates. A larger 46mm piston is centered in the monotube design. GReddy states that its Type-S coilover spring rates are optimized to provide additional travel and longer stroke for improved ride and road surface compliance.

BRAKING NEWS

While the factory FR-S brakes may be adequate for street and mild track use, a properly engineered big-brake kit offers substantially more thermal capacity. The large 330mm two-piece rotors of the GReddy brake system allow for extended periods of abuse. When asked to stop 2,900 pounds of car and driver on an FR-S application, these rotors should barely break a sweat.

GReddy 6-piston front and 4-piston rear calipers ensure that the pads make an even contact with the rotor while providing the proper pedal effort and travel. Earl’s Teflon-lined, stainless-steel brake lines are included with the system to eliminate pedal squish.
GREDDY SPECTRUM ELITE SE

Considering that GReddy currently offers five different exhaust lineups, the first order of business was to select the proper series for a future FR-S tuner. Ultimately, GReddy chose the Spectrum Elite series based on its combination of sound, performance and looks. The Spectrum Elite series combines increased diameter tubing with free-flowing muffler(s). Sound control is below the 95dBA standard while the tips are sized to avoid unwanted attention. The system prototyped for the FR-S utilizes a single muffler with dual inlets and outlets. Piping diameter is 70mm.

THE END RESULT

Some simple touches definitely allowed this Scion FR-S to stand out from the crowd. While GReddy had just a week with the FR-S, we can only imagine what the future will bring. Air intake systems, strut tower braces and chassis reinforcements are likely to be among the first additional tuning offerings for the FR-S. Later, we expect to see the aftermarket offering off-road headers, straight pipes, camshafts and maybe even stroker kits. Will there be aftermarket turbo systems? Yes. However, they’ll have to be properly engineered to work with the high-compression engine and D-4S direct-plus-port fuel injection system. Needless to say, the FR-S is going to be a tuner choice for a number of years to come.

Oh this "feature" is new ....

not really a repost. it's a shame they couldnt bend up at the least a short ram intake for this car. kinda sad they couldn't imo.

Yay!

Time to search for slightly larger wheels then this... larger i mean less offset.

That car is gorgeous!!!

Greddy had a very limited time to mod this car. I was pretty amazed to see they did this much mods within short time period

I like this post. Really nice pictures and was an interesting read. Thanx alot!

Yep. The article says they had (less than) a week.

That is some awesome work for just one week!

So the 5x100 hubs they did not like them either. At least they found an easy conversion. I wonder how much it is?

about $150 for a set. There is already existing 5x100 to 5x114.3 adapters. Do a google search.

such a poormans_LFA:thumbsup:

:happy0180:

wonder how easy it is to the installation?

Sweet article! Exhaust looks pretty cool!

Look really good. I like the NA engine tuning parts with cams and increased displacement. Can't wait for this.

All it needs is the better looking HID headlights from the Toyota 86 High Spec, and it is golden!

Definitely a poormans_LFA:thumbsup:

Agreed on the headlights. I can't imagine that it was such a large cost reduction that it was necessary, I mean... even Kia has HID and LED strips on over half of their vehicles.

yea they did throw together a lot really quick i will give them that.

So this car just has 5X100 to 5x114.3 adapters? So the offset of +45 or whatever would really come out to about +25 ish prolly?

with this statement:

It is a full hub conversion not an adapter like what you are probably thinking of

The GReddy FR-S looks like a Supercar. It made me want to with black for my FR-S, even though I already have a black car.

good post . thanks for the new info


It is a full hub conversion not an adapter like what you are probably thinking of[/QUOTE]

yep and that makes sense why there is a bearing hole in the axles of this car.

Hopefully they will make it into the final production car. Nothing is set in stone yet and there is still 6 months to go.

I can see it //TRD Headlamp upgrade : $550.00

said it before and i'll say it again: when @ the FR-S premiere we asked Jack Hollis about the L.E.D./HID lamp combo. paraphrasing his words, "how many people want it and how much do we sell it for?? that is the question we're asking right now. probably won't be available at launch. probably another six months later."

Actually we don't know that unless someone got a good enough pic to see if the spacers are there between the rotor and wheel. Since we don't know what the stock hub/knuckle looks like (but it's likely a WRX unit with that hole in it anyways) you can't determine much of anything from that pic. Those aren't STI knuckles and I'm sure Greddy didn't make their own, so unless the 5x114.3 bearings and hubs can be pressed/bolted into the wrx knuckles then a simple spacer coversion is much more likely.

Didn't the MotoIQ determine it was just STI calipers and rotors (and motos pics show that too, they don't show a 6/4 setup)? In that case, did Greddy do two of these or is dsport wrong?

Looks like the bearing and studs are bolted to the hub, chances are greedy found another car with 5x114 bolt on bearings and modified them to suit the gt86 hub

I think after release a "real" look/tear down will be needed (if they are in fact Impreza parts "slightly" modified then the questions are:

How?

When?


Then get the ball rolling


AS1 hub ;)

Why bother with that when they could just bolt on a set of cheap spacer adapters? They had a week to setup a jig to make the exhaust, figure out what suspension parts to use, order whatever parts they needed, etc. Searching for and finding that perfect bolt in hub isn't likely something they would have had time to deal with. Either the STI ones directly fit in the as1 hub (happy jdlm? :P ) or they just went the easy and fast route.

If I had a week I know which route I would have gone.. 1st try to bolt on STI knuckles, and once that failed, bolt on spacer adapters. They did it for a reveal, it's not like it had to be the best setup ever.

I am intriqued by a real conversaion to STI hubs simply for easier 17x8.5" wheel selection but I won't run spacer adapters to get 5x114.3 instead.

:thanks:


Knowing the standing relationship that GREDDY and Toyota have I am sure they opened the parts bin or gave inside info.

Agreed. I'm not even sure they are slightly modified. There will be a.. hmm not sure what the correct word is, but a "shaft" to replace the end of the axle for the bearing/hub assemly to slide onto... that may be all that's bolted to the hub. It needs something in the middle so the bearing doesn't destroy itself.

Yeah but in this case it'd be a Subaru part.. for RWD.. which doesn't exist :) a front knuckle with no axle through it... The WRX bearing is pressed into the knuckle and then the hub is pressed into the bearing. Standard stuff.

The only modification I can see is bolting on an axle end or what not for the bearing/hub assembly to slide over. I would not be surprised if the hub/bearing assembly belongs to a Toyota FWD car (using the rear bearing/hub assembly) though, simply enough to use that on the front since the setup would then be the same (just a threaded shaft, slide the assemble over, put on a washer, and then tighten the axle nut.)

so they can get a head start and sell the conversion kit at launch or close to it? :iono: think about it. they have a golden opportunity to prototype a conversion kit before anybody else even has a chance to see the car, let alone touch it.

True, but that's a risky move and only the front is really easy. The rears are going to be worse. Unless there's a bearing that fits in Subaru's 5x100 impreza hub but holds the STI (or some other subaru) 5x114.3 hub. I'm not a subaru person so I have no idea what they do to convert to 5x114.3 so maybe that product already exists. I'm guessing Greddy went with those wheels for the look then had to adapt it to 5x114.3 just to make it work.... but then again recent greddy products I've used have all been trash (like sr20det oil pans that leak due to shitty casting) so maybe I just don't have enough faith in them lol

I'd love a real 5x114.3 conversion hub, or just the ability to press in STI bearings and hubs, but I haven't seen anybody post links to WRX guys doing that.. the WRX market is much bigger than the AS1 market so you'd think it would have been done there already if there was a good enough business case for it.

I guess I just like to see evidence of things posted on here, and none of the pics/info provides any evidence that they made conversion hubs at all. I'd really love to see between those wheels and the rotors as that would answer the question.

Just went back around and checked some of the pics and videos. Based on the offsets and how flush those wheels are, and the spacing between the wheel and calipers, etc I'm pretty much convinced they are spacer adapters. I hope they aren't (but then I also hope it's not greddy specific parts) but without better evidence it just looks like spacers are used to me.

what's wrong w/ spacer adapters??

I not sure I follow you. Are you saying you just think it's an adapter? I know there are adapters to convert 5x100 to 5x114 in existence already.


*edit, saw second post.

Meh...nothing wrong with space adapters to me.. Doubt I would do anything but daily drive on them though.

I have friends that own STIs and other Subarus and they hate the spacer kits because of the construction and hitting the wheels when they are on (plus extra long bolts)

that sounds pretty lame. sounds like a hub conversion kit would be a lot easier/better to live w/.

For having such little time, GReddy did a fantastic job with this car! :bow:







Ha.. wow. ain't that the truth! Never would have thought to compare if you didn't post these pics :happy0180:
