They are quoting a curb weight of 2689 lbs now.

Do want!!!!! Price will kill it for me probably. Love the looks, especially in a dark silver color. Interior is probably like most new cars and too flashy.

Awesome, so that bumps it up two places. This car is looking more and more appealing. I wonder what a fully stripped out and caged car would weight?


S2000: 237hp, 162tq, 2864lbs = 12.08 lbs per hp
ITR: 195hp, 130tq, 2639lbs = 13.53
GT86/BRZ: 197hp, 151tq, 2689lbs = 13.64
RSX-S: 201hp, 140tq, 2840lbs = 14.13
Civic SI: 201hp, 170tq, 2877lbs = 14.31
NC MX5: 167hp, 140tq, 2511lbs = 15.04
NB MX5: 142hp, 125tq, 2441lbs = 17.19
NA MX5: 133hp, 114tq, 2293lbs = 17.24

To rival the s2000, you would need to squeeze 20whp or so out of the motor. That may be doable with bolt ons and a re-map. Hopefully COBB's accessport works with this and a map becomes available for exhaust/intake.

The RSX-S is another good comparison. Who wouldn't want to daily drive an RSX-S that had more torque, 150 fewer lbs, and RWD?

Let's just hope the aftermarket gets some serious power adders going early.

I don't think we will see many big builds right off the bat, as Subaru has a very good warranty. I doubt many people would want to jeopardize it. I have a feeling we will see a lot of exhaust/intake + acessport builds because they can be removed if there is ever a warranty problem.

I'm sure there will be turbo kits almost right away, but with the quoted 10:1 compression ratio I doubt we will see big boost builds unless an STI or EJ20 or similar gets swapped in.

Possibly. Fixed rear seats or fold-downs with cross bracing would likely have been better for chassis stiffness, but the Toyota group specifically said that's one of the reasons for the incorporation of the fold-down rear seats with the large pass-through.

I am sure that will depend on the size of the wheels and tires.

Looking at the NC, though, notice the space behind the seats and the "air" that will be enclosed via the FR-S fixed roof.



From MotorTrend.com:
Quote:
The trunk has a rather modest 6.9 cubic feet of trunk space with its fold-flat rear seats up. Fold the seats down, and Subaru says a driver can easily fit a passenger, a full set of racing tires, a helmet and tools in back - ideal for autocrossers who bring their gear with them. Subaru also said that the instrument panel was designed with a rollcage in mind, meaning those who race their BRZ won't have to tear up the dashboard in order to mount a cage.

Watch



I'll be waiting for the STI version. Which is sure to have a turbocharged motor with plenty of other add ons. I'm sure the price tag will be $30k+, but I think it'll be well worth it.

STI + 2700lbs + RWD = WIN

Not to mention I do like the styling of the BRZ as well.

Suspension info here (not double wishbone) ---> http://www.motoiq.com/magazine_artic...86fr-sbrz.aspx

MotoIQ says 12.5 compression...not 10 to 1

MotoIQ also says the 2622 lbs listed weight is a JP version that is dry. They expect US version to be ~90 lbs heavier. I think a 2700lb wet weight is still pretty decent.

MotoIQ does not mention Ultra Low Center of Gravity... :(

Low

Gravity

The low center of gravity thing is in the press release from Toyota. And they are the same chassis so I'd assume it's the same in the BRZ. My mistake on the motor compression. Sounds like it's a good candidate for a low boost Rotrex set up. Oscar should get on board with Cobb and build a bolt on kit with a Cobb acessport map. That would be the ****. And design it in a way that it can be removed without too much hassle for warranty and maintenance related work. I'd say 250whp and 200wtq would make a pretty damn fun daily driver :P...

I think this car would be really fun on the track too with a build N/A flat 6
I think I read somewhere that they designed the car to be able to hold 4 wheels in the trunk or something.

lol, no camber adjustment in the front. 5x100 bolt pattern. new rear diff., brakes could be pulled from an impreza, so it might be set from the get-go there.

I know porsche/BMW use macpherson strut, but do we know if subaru can really get the same results? Not being an expert on this, but how do the subaru guys deal with positive camber once dropped? Or is the factory geometry setup well enough that you don't have to worry about that unless shlammed and frush!?

Any lowering solution for this car will come with camber plates. I've driven some BMW's and RSX's with McFuck suspension and they handled great (although they were not stock).

The thing that REALLY kills it is the 5x100 bolt pattern. Seriously... what the ****.

Yes, I understand camber plates. The issue I am referring to is MacPherson strut setups will go from negative to positive camber depending on the angle made with the strut.

lowering the car will cause more static negative camber.

I am sad it does not have a double wishbone suspension, but I expected McPherson struts because it is cheaper and they did not have to design a whole new suspension. I will keep faith that they worked some magic on it.

Track - supposedly the diff is from the lexus is250 and similar cars.

I would have liked to see a 4x100 wheel pattern....

Not all strut cars require plates to adjust camber, depends how the strut is built. Normally you can just use camber bolts.

Genesis R spec comes with adjustable bolts from the factory. I doubt it will need a plate, could do slotted mount holes, like minivans or camber bolts. Plates arent all that common.

the camber curve changes as suspension compresses. sure static camber maybe more, but as you compress the suspension in a curve, you will lose negatie camber (in othewords the curve adds positive camber, in otherwords being low is bad)

In this picture, angle of the CA w/ strut determines the camber curve. I think its 90* is the maximum. Note the middle diagram, shows a positive camber curve as suspension compresses.


Can we stop being blonde about this please? positive camber curve sucks. If a macpherson strut is lowered enough, it has it. That sucks, how do the subaru guys fix it?

They install top hats.

The only downside to McFuckstrut is on some cars you need to run huge amounts of static camber so you have enough on bump. On my friends BMW LS1 SPO race car, he runs something like 4* up front static for the tire to heat and wear evenly.
