Hmm... I wonder if placing a S/C would alter the weight balance enough to cause any major handling differences.

Speaking of FI, I saw this one picture of a WRX owner where he got a new intercooler. Because he changed the location of the IC, the hood scoop wasn't exactly purposeful so instead, the guy installed an oil cooler where the original IC was so I guess a major win-win.

Adding a SC and replacing the stock battery w/ a lighter one would cancel each other out. The CoG would rise just a tick but then drop more if you end up lowering the car. I'll be shaving an inch off at least, but not enough to scrape or smash bumpers and doors on curbs. The car has about 6.5" of ground clearance stock which is a lot! It was designed to clear lots of stuff on the road from the beginning. Everything affects the balance, the minute I remove the spare tire and tools, the original balance is gone. I don't mind, I'll going w/ stiffer front springs anyway which will make it more neutral after all the weight loss which is biased toward shedding pounds from the rear and center.

Leftlane's response to the Jalopnik article: http://www.leftlanenews.com/topless-turbocharged-scion-fr-s-canceled.html

I'll just let that there, heh. Did some digging, looks like in order for Subaru to get the BRZ they had to agree to no turbocharging until after 2015. Apparently around the same time a KERS FRS might show up. Hmm....

Seeing how the Forester XT share the same block as the BRZ, minus a few alterations, I wonder how it will fit under the BRZ's bonnet. It might be a little ambitious because the FA20 in the BRZ is specifically designed for the RWD layout (meaning the engine is pulled backwards more than normal due to a lack of a front differential) and the FA20 in the Forester is designed for the AWD platform, but without seeing the engines side by side, I'm just speculating here.

I've heard that Bilstein released their kit for 86 owners and apparently the feedback has been positive. If it was my money though, I would wait for an Ohlins kit first.

Still trying to decide if I want one now or wait till the speculated 2015 facelift... But that's a gamble itself here as you have to literally wait 4-6 months to get your hands on a 6-speed BRZ, especially in blue. If the situation is somewhat similar with the current model when the facelifted version comes out, I might not be able to have the option of purchasing the current model IF the new facelifted version looks like shit or whatever. But Subaru has been pretty good with model revisions so I think I might trust them this time again.

If you can wait, just wait. I can't wait for a few reasons.

Ohlins has been out from day one. That's who I've been leaning toward. Height adjustable from the bottom w/o moving the spring perch, no individual rebound and compression settings though sadly. Not sure I'd get Bilstein over a KW v.3 setup either unless it was an active system. I looked up Moton but it seems they were bought out and basically killed off/assimilated. Whichever coilovers I got, I'd swap out the included springs for a set of Swift's special alloy w/ fewer coils/turns/weight. Especially for a daily driver.

Btw, went in again to check out the fuel filler door and AC temps on the FRS. They threw the keys at me again so I went for another drive w/ all the nannies off, hehe.

Always funny watching a passenger try to step on an imaginary brake pedal.

Ah I meant to say no adjustable damper settings for the Ohlins. That's what I'm most interested in because I'm not a huge fan of the rebound setting in my KYB struts. It's a little too slow in the front and a little too quick in the rear, in terms of rebound. After riding mtn bikes for nearly my entire life, I've pretty much attached myself to damper settings after crashing COUNTLESS times due to incorrect suspension settings, maybe that's why I'm leaning towards the Bilstein offering rather than the Ohlins.

I haven't done too much research on the Swift offering. What are the spring rates?

They are adjustable, you can see the knobs on top of the mounts. Here's the shock dynos showing the level of adjustability between the Ohlins and KW Clubsports. Ohlins on top.

Swift can make pretty much whatever rates you want in whatever size you want. You can read about them below.

It's funny how they go after the "all springs are the same" crowd, lol. I guess some things in life are just universal.

Here's the sizes they have normally for coilovers: http://www.swiftsprings.net/products/universal/metric-coilover-springs.html

Interesting. You're always a good source for information Anax, especially when it comes to the 86 for me haha.

What would be your "ideal" spring rates if you were to choose? Can be either for track, street, or a mix of both.

To be honest, I would be guessing most of the figures if I had to choose the spring rates myself, just like how I do in GT5 haha. Mostly a trail/error thing on the PS3, but IRL, things can get expensive with trial/error.

Thx. I honestly can't answer that without going through all the weight reduction mods and getting the car up on scales. Driving style and use will determine it as well. I'll likely go w/ whatever prevents brake dive during as much as possible yet is still enjoyable on the crap streets of California. Then pick a balanced rate for the rear that allows me to rotate under throttle but tries to preserve neutrality. It's just too many factors w/ ride height, sway bar choice, weight distribution, tire/wheel selection to offer a simple, clear, definitive answer. So for me, start w/ balancing brake dive and street compliance and go from there. I'll need to parse the entry speeds of the corners I anticipate, braking of the kits I'm looking at and do some maths.

What I would do for a general baseline is see what range the big names are running w/ their kits. Seems Billstein was 5.0/5.2, I think Ohlins is 5.0/5.0. Stock/OE is 2.4/3.8 on FRS and 2.8/3.5 BRZ I believe (based on conversion of data from Newton/mm to kg/mm acquired from Eibach). The Swift lowering spring kit is 3.0/4.5 FRS and 3.8/4.5 BRZ for just the lowering spring kit and stock dampers. So I think you can see a picture developing. I need to find out what my friend runs on his track Integra.

True. It just seems that everywhere I look (all the major 86 forums) either ride way too fucking stiff or way too mellow, but this is purely on observation. I don't know how well paved roads are where you live, but here in Vancouver... Oh boy. I'm no pussy when it comes to stiff rides, I actually like stiffer over softer, but using the BRZ as a DD with track-spec suspension might make me one cranky ass driver. No wonder my friend in his Integra Type R is always mad when he drives over rather than biking over

I wonder how the Ohlins performs with identical rates on a 53/47 car.

Oh yea, when you mentioned the 86 having a 6.5' clearance, I was surprised to see that high of a figure on the 86. Then I realized that Subaru placed everything as low as possible giving me the feeling of an already low car inside, but when you get out of the car and look at the wheel arches, too much clearance!

I'm constantly looking at wheel choices for the BRZ, even though I'm nowhere near close to owning one. So far, I like this http://i.imgur.com/C73GC.jpg the best, but with the Grey only. I wonder how it would look with the WRB
