It's not the CR ratio that is a limiting factor, 12.5 is doable in a turbo application. The limiting factor will be the availability of a good tuning solution for the D4-S fuel system and how the engine is designed, along with how the internals are made.

I know for sure that this is not the case because most tires will have anywhere from 8-12/32nd's of tread depth and that equals 6.35mm to 9.525mm of tread depth on brand new tires. The only time the tread depth gets greater for cars would be for snow tires. My brand new BFG Mud Terrain KM2's have 20/32's of depth new and that equals 15.88mm.

The difference in height would either be tire size, 215/45/17 (24.7" diameter) compared to 225/45/17 (25" diameter) would be .3" or 7.5mm or the ride height of the two cars could be different due to springs etc. I highly doubt that they are going to use two different shells/unibodies for the different versions. It would drive up cost of production too much for a relatively lower volume car (in comparison to Corolla/Impreza, etc)

Until I see official releases from Toyota/Subaru for the USDM, I'm not counting on anything that comes out through these leaks etc. It's not that I don't love all the info coming out recently, but I don't want to get disappointed when something doesn't make it across the pond.

The counter on the top is this page is moving too darn slow! :sigh:

awesome news! thanks for the update

Wow it looks great. I really like the light around the head light. I'm glad I did not buy that miata I test drove this weekend.

I still like the Toyota version better! I don't like the BRZ front grille. But the rest of the car is tight! I need to see the whole car like the FR-S.

Just because the Japanese version of the FT-86 has the clear taillights does not mean the US version will have them...

I agree with you. I like the Toyota version better. The front grill is keeping going to the scion dealer...but I need to see the BRZ production rear end.

I agree. I don't care if it's a scion. I actually like that this car is going to put scion on a better higher level!

I also think this is going to be Subaru's best looking car. Let's face it Subaru does not know how to make a beautiful car. The wrx and Sti are alright but they ain't pretty. The BRZ is. This car is gonna get people into the Subaru showrooms!

You can't say that...you don't know what the production BRZ lights look like.

Also some of us like the scion front end more than the BRZ front end!
Remember the high resolution pics of the FRS are of the low spec version since it has not fog lights and no LEDs in the headlights like the high spec version.

We have to see both cars side by side and in both trims...

I agree. 12.5:1 ratio is doable, but 10:1 is whole lot better. I agree that it need tuning supports for D4S, so let's hope there will be a ton.

I wouldn't say BRZ is better than FRS or vice versa. Like RRnold said before, Subie version can turn off completely in real life. We need to wait and see first. Though, if all things equal, I take Subie over Scion any day.

I just hope they don't do a Porsche Philosophy and don't get me wrong I love Porsche I want to own one one day. But I hope it's not one of those We give you less and charge you more IE Boxster Spyder; Because with the way Scion is trying to win people over. It's going to be at least antiquate.

That's testing. In production they will all come with tire x.

Basic car struts won't change ride height.

My opinion is still that one or both of the measurements is simply wrong though.

Two things:

First, can we add the "T" word to banned words here, so it just comes out as "*****"?

Second, maybe the extra 15mm in height is due to a huge rear spoiler. :D

Oh yeah I forgot the spoiler! Hehe!

The difference in ride height will most likely be the different spring rate used for the Subaru.

From what I see no I think I'll like the Subaru alot better than the Toyota. IMO headlights, front bumper are better than Toyota's from what I see. I also like the STI Concept taillights better, but now we have to see if they make it to production. But the rear bumper is better on the Toyota.
