We have only built a 2008 and 2009 in B-Spec trim, our 2007 and 2012 were H Prod cars.

Our 2009 BS was raced this past January, without driver and 3/4 fuel at the end of the race it weighed: 2197
The driver was a 6'+ and 230lbs, so it just made minimum weight.
This car has a way overbuilt cage (because when we built these back in 2010 the thought was BS was going to use Grand Am specs for cages), 1.75"x .120 tubes, it is a heavy cage. The car also has a full fire system, and ran on steel wheels. Any normal size driver is going to need a lot of ballast and start with a full tank of fuel.

In H Prod trim when I weighed both the 2007 and 2012 with empty tanks the difference was 100lbs. However, the 2012 did not have the benefit of a carbon hood or hatch like the 2007, and at the time the 2007 was on a much lighter 13" wheel/tire package. I think the actual weight difference between the two cars if setup exactly the same would be less than 50lbs. With the longer, more stable wheelbase, and cleaner aero the 2012 should be the better choice.

From the latest tech bulletin (figures, just as we are stripping the BS car for the crusher)

No turning back now :) Dropped off the car for CAGE!

Sweet build.

I'd love to build a yaris for track duty to eventually replace my turbo tercel track day car.

With the weight limits it looks like for bspec...it might be easier to build a sedan...take advantage of the slightly better aero

So we are weighted down an extra 80lbs with or without the TRD suspension?!

Not only is the weight now 2500lbs, the 2014 GCR still does not show the kit.

Yes but the Mazda2 is back to 2350 & Chevy package is listed!

I would imagine if you printed the Fastrack 13-12 where it lists the TRD package you would be fine. Englewood or Topeka, they still can't keep it straight.

I did notice all cars get adjustable swaybar links. Is there a good model to use with the TRD bars?

xnamerxx · 01-08-2014, 11:22 AM

TRD bar isn't legal.

Correct, but the rest of the needed parts are going to have to be requested from SCCA and fight our way thru the approval process.

Larry@CFR · 01-08-2014, 07:48 PM

If you guys want to see some great B-Spec pictures from SCCA Major at Sebring, check Facebook at 'Michael Lilley Photography and Design' and search for '2014 BFGoodrich Tires Sebring Super Tour'. The Saturday set starts with B-Spec group and a Fiesta getting punted on the 1st laps! 7 B-Spec's were entered and 6 showed up. PWC TCB driver Ernie Francis, Jr was DQ'd on Sunday due to "Unsafe Driving". Wonder where he learned that??

xnamerxx · 01-09-2014, 11:02 AM

If it were me I'd start with trying to get another suspension approved, the TRD isn't good enough for track use. Given Bilstein has worked with my HR springs it should be pretty easy to adapt the HR coilovers to something useful.

xnamerxx · 01-29-2014, 12:09 AM

Well throwing my hat into the pool with a B spec Yaris. Got 2 Honda Fits signed up for the license school so I should have some fun trying to keep up with the Hondas.

Been thrashing for the past few months trying to get the car ready and its finally close enough to be legal to race. Gotta add quite a bit of weight for it to hit the minimum 2500lbs

With the stock suspension car rides kinda high.

Should have grabbed the blue mirrors. Remember that weight is with driver at the end of the race.

xnamerxx · 01-29-2014, 12:28 AM

Yeah it really would have matched the car better with the blue mirrors but I've got some ideas for livery on the car. There has been some talk at work about adding a corporate livery to the car but I don't think it'll gain any traction.

I figure the car would need about 100-120lbs with my weight when its all said and done.

Put half a tank of gas in and see where you are. If you start full you won't get under half in a 40 min race.

Is the TRD suspension still on your car?

xnamerxx · 01-29-2014, 01:58 AM

TRD is still on my car, everything is getting pulled off and replaced sometime this week. Although I've been really tempted to throw the STF Bilsteins on the car just to see what its like.

RJay · 01-29-2014, 03:57 PM

2500 lbs? That's quite some weight for a little car, that's heavyer than stock or isn't it for your modelyears?

I weigh 1035 kilos / 2277 lbs with just my road car with the stuff I have in it on a normal day including me & half a tank of fuel. (Yes, that's my yaris. My bmw weighs about 30-70 kilos less depending on fuel and including me)

xnamerxx · 01-29-2014, 04:02 PM

The car has never been vetted so the minimum weight might change in the future, depending on how competitive the car is with its competition.

I've been told the Fiat 500 is so slow that all the other cars had to be dumbed down so it could keep pace.

My autox car weighs 2110 with a full interior and a really lightweight exhaust, but it doesn't have a cage to deal with.
