There are four pages talking about GT5 and the Yaris Club Sport Challenge - which used the other two Yaris race cars (#98 & #20), including details on the cars. There is no coverage of the HP car (#99), because we did not let the press play with it, only the guys from Toyota, JGR and Sony got to drive it. Lots of pics of all three.

Nice. Might have to pick up a copy then.

The May 2011 issue of SportsCar magazine, featuring the second installment of the Yaris project, just hit my desk... SCCA members should have it in the next 5-10 days.

Where might non-members pick up a copy?

You cant. Membership has its benefits.

You should be able to order one via our website, once it has become a "back issue": http://www.sportscarmag.com/index.asp

So I decided to kill some time today by replacing the front subframe assembly - A arms, brakes, hubs etc. The cool thing I found is that the stock front bar on our hatch is 24mm (blue dot), and the one on our spare subframe (that came out of a sedan) is 23mm (purple dot). This smaller front bar should help the car rotate.

I'm curious to know how softening the front will help rotation. Can you explain it so us noobs get it?

A swaybar transfers grip to the opposite end of the car. When you put a big rear bar on you force weight to the front - this can usually be seen on a fwd car when the inside rear tire is in the air. The car weighs X, and now the other three tires are carrying this weight.
On a rwd car a big front bar can be used to try and lift the inside front, this forces weight to the rear, helping acceleration off of the corner.
Picking up a tire is the extreme, but even when this does not happen the bar is always trying to lift the inside tire.

Using a smaller front bar will help keep the inside front tire in contact with the road, and transfer less weight to the rear. The car thinks the rear bar is now bigger. And I have stiff enough springs that it still wont roll excessively.

A smaller front bar is a common mod on a stock class fwd car, it is the only bar you can change, and it really helps a car with an open diff put down power.

A small bar can hurt in slaloms, but you can get that back with more rebound in your shocks.

loren used to disconnect his front bar for auto-x, iirc

This coming weekend (April 30-May 1) is the Cal Club SCCA Double National and BFGoodrich Tires Super Tour at Buttonwillow Raceway Park.

Saturday is a standard National Club race, but on Sunday things get turned up a notch thanks to BFG. The Super Tour is like a traveling version of the National Championship Runoffs - it features live timing and scoring (via the web), enhanced race coverage (both on site and in publication), and the most important part, the champagne shower on the podium.

We thought we might get as many as eight HP cars, but the Honda Fit is currently MIA, and one of the front runners from Norcal had to pull out at the last minute. It should still be an exciting race, Gary Wittman (the Austin Healey I was trading paint with at Willow Springs) will be there - and both of us have been working in the garage to find more speed. There are a number of other British roadsters, and Cory Markos in his Honda Civic. Its going to be fun.

If you can't make it out follow the link at scca.com for live scoring on Sunday. We are race group 4, and should be on track around 1:50pm.

Took yesterday off to finish up a few details for the upcoming weekend... Purged more of the unneeded wiring harness, set the alignment and installed some brake cooling ducts.

We have never had an issue with the brakes, but the 13" wheels make for such a tight fit (I literally can not use a tape weight on the inside of the wheel, the caliper will hit it), and it everything is getting hotter. I am concerned both about brake temps, and the seal material in the three-piece wheels.

I did not want to open another path for air into the front of the car, so I squeezed the hoses into the grill opening. I would have liked to run the hose all the way to the caliper, but again the small wheel/tire package made this impossible - there is just to much going on with the CV boot, strut and tire clearance. So I attached the end of the hose to the swaybar link. When the suspension is at static ride height the hose lines up just behind the caliper - the suspension can move up and down freely, and the hose stays in the same location.

It's not as good as feeding the air right on to the brakes, but I am happy to have some airflow in the general area, it should help keep all the parts happier.

This looks like it will work pretty well. Does squeezing the hoses restrict airflow? Can you have them terminate right behind that grill? Does that grill have to be there?

I tried to squeeze them as little as possible, which is why the grill is a little deformed in that area, but the volume should be the same.

If I would have put them behind the grill, which was my original plan, the grill would have blocked some of the tube.

The front bumper has to "resemble" the stock one, so I would say that it does need to have the beams.
