Have you replaced the brake lines with SS lines and the brake fluid with something more race oriented like Torque RT700?

I don't run SS lines in either of my racecars. I do run a high temp brake fluid, but I'm not that picky about brand. There isn't all that much braking in a B-Spec.

I'm not running the rear ARB because it's not part of the kit.

So I'm assuming in that class, the rear sway bar would be illegal since it didn't come in the TRD package???

Ah, didn't know not much braking is involved in that class.

Each B-Spec build has specific components and the ARB isn't one of those. That's the simple answer. How one designs a kit and then modifies it probably involves discussions with the SCCA. Hopefully Jason will enlighten us...

Toyota had no official interest in supporting B-Spec when the class first came on line - still don't - it gets the same level of support as an other Club Racing class.

Because we were already working with Yaris marketing team we were asked to work with SCCA on the B-Spec program. But with no support, or interest from TMS, there was little to do. Originally the car was going to run in BS nearly stock. We suggested tossing in the already available TRD springs and shocks just to try and lower the car a little, making it less prone to a roll. We did not ask for the rear bar because adding a torsion bar to a stick axle is kind of pointless. You can call it a swaybar if you want, its not, and does not function as such, just cost money and adds weight.

If you take a look at most of the other BS kits they are all adopting the Mazda/CorkSport "rear bar", which is also not a swaybar, its tube with tie rod ends they use to bend the axle to adjust toe. You can accomplish the same thing with shims on the rear axle.

Recently a new BS committee was formed, the previous one was made up of manufacturer reps, the new one is racers. The new committee wants to speed the class up, so they started opening up the restrictor plates on the fast cars (Honda, Kia, Mini, Chevy), and giving things like a CAI to the slower cars. The Mazda2 also got a header. All of these changes are just leaving the Yaris further behind due to the lack of an ECU reflash - and they wont allow a piggyback.

At the 2011 Runoffs they invited all of the manufacturers that had built BS cars to bring them for a demo race. We shipped out one of the cars we had used for a Sony Play Station program (built to BS trim), we were very disappointed to find out the "demo race" was five laps behind a pace car. We spent the money to ship the car and expected it to race, so we started looking at other options... Since BS was not yet a class, we could only field the car in H Prod or Showroom Stock C. We found an SSC driver that had engine problems in qual, and let him run the Yaris - giving us the first BS car to compete at the Runoffs.
