SCCA Houston Region B Spec build :)

[Larry@CFR]

To those who have built a Yaris or are in the process, what weight is the gutted body and what is the weight with a full comp SCCA cage? I am looking for the difference in Andrew's 2009 & the 2012? Thanks!

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.

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?

TRD bar isn't legal.

Haven't heard from FHT_Racing in awhile, how's the build going in Houston?? Saw Joe McClughan used Taake's TCB car for a B-Spec SCCA Major race last weekend and set the lap record. Unfortunately, no competition there but he ran well.
