Are you going to have any B-Spec parts or race tires on it when you run?

Jason, where do I find the allowable B-Spec mods for the Yaris, I can't find anything in the GCR? Is it strictly whatever TRD offers in the way of struts, shocks, springs, and swaybars??

We submitted the parts (TRD shocks and springs) for testing, and requested the part numbers be put on the spec line. They should show up eventually.

The car also needs a weight break. I think it should weight the same as the Mazda 2, based on power and gearing, but without more on track results I doubt they will adjust it.

Sounds about right, I've been given permission to run the car in NASA with all TRD parts as either B-Spec or PTG Limited Prep car. Thinking of keeping it B-Spec so I can run both SCCA and NASA, since I'm already running SCCA Solo events in STF with my 2010 Yaris.

I will be running it in stock form for it's first time out. I do have some Dunlop DZ101's with decent tread left though...

What did that B-Spec end up weighing before ballasts?

Thanks,

We built the car back in 2010, and I don't recall the exact number. However, it was not built light... The car was built with a 1.75x.120 cage (at the time it was thought this might become the B-Spec standard due to Grand-Am possibly being the officiating body, but that did not happen), so that is extra weight. It still has the complete sheet metal in the front doors (no Nascar style bars), plus both power windows and some of the audio gear is also in there. We also mounted the drivers seat on sliders with a back brace to accommodate guest drivers. Complete fire system. Has a TRD muffler, instead of a strait pipe.

When it ran at Fontana a few weeks ago it was on heavy stock steel wheels, and I filled the gas tank till fuel was right at the flap, finished the race 7lbs over minimum - which sounds great, but we also had a 6'+, 240lb+ Swede behind the wheel.

Figure on a standard build with an average size driver you are looking at 150-200lbs of ballast.
