Wish I could put it in... Ordered flywheel bolts from TRD on Dec 12th, five show up. On the 21st get an email saying the last one arrived and is shipping to me, should have had it on the 23rd - it never showed and they are closed for the holidays for about ten days.

Started calling dealers today, nearest flywheel bolt is in San Fran. So the car will live on jack stands for another few days over a single blot.

What's special about TRD bolts? Aren't they all grade 10 bolts?

Racer pricing from TRD.

WOW, the OS Giken Super Single was a bugger to install... Usually most clutch's have enough play in the splines you can pretty easily stab the transmission and bolt everything up. The OS Giken is so tightly machined you had to have everything lined up dead on. Working by myself it took an hour to get the trans bolted up, normally this is a ten minute job. I was beat.

So far I have only driven it in and out of the driveway, so driving impression is very limited. Pedal effort is high and it grabs hard. Would be great for a FI car, but I am not sure I would use it on a daily driver. Hopefully I will get a better idea of what its really like next week.

That was a nice little drop.

OS Giken is making a new diff with more plates for the Yaris.

I don't think we are even using full lock up now.

The OS Giken IMO has always been a grabby clutch. Tilton would have been a better choice although it is more spendy. It is very street friendly and has a super light/soft pedal.

Got the new Hoosier radial slick to test out.

Could you through on just the clutch assembly with the bolts, if possible. Curious to see how much that heavy PP is.

Just got back from Willow Springs, shaking down the 2012.

Considering how little it done to it when compared to the 99 car, it was fast. Just needs a little more tweaking, but a great first outing.

cali yaris · 01-11-2012, 08:29 PM

Those tires...so much meat.

How do you think (so far) the car compares with the one you race?

The rear fenders on the 2012 don't like me so much anymore, I spent a lot of time with the fender roller making sure those things would fit - we did not want to flare this car.

So far I am impressed. The longer wheelbase makes the car much more stable, and it does not get away as quick when it does break loose. The car exceeded my expectations for the day, it was nearly a full second quicker than I expected it to be... Still not as quick as the 99, but so far we have been unable to get the AEM mated up to the new ECU. Once we get the parts equal on both cars it may have a slight edge due to the lower roof-line and more stable platform.

However, I am doubtful I will get it as light as the 99 (which is down to 1800lbs), the lack of aftermarket body panels is going to make it hard to drop those last few lbs.

I sure do like the looks of it better than the old car.

Are you having issues with the AEM on the 2012 ECM, or have you just not had a chance to sort out the wiring differences yet?

We have had vendors looking for the plugs, so we could build an PNP like with did on the 99, but no luck. And so far we have not had a chance to try the hardwired method, we will likely start going down this road after the race next weekend. I hate to go hardwired because it is really nice being able to plug in the stock ECU if we had a problem, but we may not have a choice in this case.

I think the new connectors are from Sumitomo. It would probably be easier to get an engine harness and ECM from Toyota to harvest a male and female set from.

Just got the new head with Jun cams back from Loynings... Oh how I wish I had time to install it and retune the car before this weekends race.
