Asked Craig (SCION rep who's invovle in this this project)
Q1. Wheels Bolt Pattern. 5x114.3 or 5x100?
A1. 99.9% it'll be 5x100
Q2. Base Price Tag?
A2. Sadly, couldn't get exact number, he said its more than current TC.
Q3. TRD Parts Coming to US?
A3. They're still deciding, but they're planning on it.
Q4. Final Weight of This Car?
A4. -+1~3 lbs from the Subraru BRZ
Q5. Release Date in US?
A5. Spring of 2012
Now, few info I got from Miwa-san.
1. This car was made to be easy changes. Example, front bumper. 3 clips on each side & 4 screws are holding the front bumper, it pretty easy to take it off &/or putting it on. That goes same w rear bumpers.
2. Inside front air vents are made big, so you can put through the roll cage bar.
3. Rear seats are there for not to function as a seat, but when to put down the rear sears, you can fit wheels, tool, & other stuff nicely/evenly.
4. It's not fastback, cuz it'll loose the chassi strength & need to add extra weight.
& lastly few things I notice about this car
1. Fenders are already rolled, top part of the wheel fenders are already rolled, so you can put wider wheels/tires without problem. Dropping the height? No problem, it won't rub (as long as you don't drop it to crazy).
2. Like Miwa-san have stated, rear seat won't be any use other than just folding it. The driver who brought the FR-S is just lil bit taller than me. After he get off the car & checked the between the front & rear seats spaces. Yeah, there's only bout 2" or less space. Don't expect to use the rear seats other than putting stuff.
3. SCION will be showing more aftermarket stuff @ Detroit Auto Show in Jan... Which, I'm interred to see what they're going to bring out.
4. Small things could of done better &/or they did better. So pretty much pro & con kinda thing
Pro - small detail things are done nicely. Example, rear bumper lower part (outer part) has small diffuser. Now that's pretty sweet. Here's the pic

Con - tow hook design. They set it up same as Impreza. Which is bottom part. Now it's common to have that design... But at the same time, they could done differently.

Pro - interior look nice. They have put some effort to make it nice. Not cheap plastic look, but actually has nice feel to it.
Con - center under diffuser wasn't done nicely. Feel lil bit cheap. Exhaust gets in the way & I understand, but felt they didn't put enough effort on that diffuser.
Now, I'll edit/add more stuff later... But I think, it's good enough info to keep the debate/discussion going til TAS & DIAS
