Lap times were not bad on 30HC tires but the car was very difficult to drive.
Saturday comes, strapped on shiny 6HC tires, balance was now crazy oversteer, went full soft on the rear bar and made some small air pressure adjustments, around 34 hot seemed ideal based on pyro temps for the tires.
As stated by many smart racers before, the first rule of testing is not to use junk tires. Since using fresh Toyos isn't going to happen, Josh and I have found that testing with the 200 treadwear street tires is a better compromise than crap Toyos. The street tires have a softer sidewall and a bit different handling feel so it's not optimum but the balance is comparable to fresh Toyos and they have stayed consistent over all the events we have done with them. Doing setup changes based on used Toyos isn't the best idea as they go through unpredictable balance changes as they cycle out unevenly. I don't think driving on crap Toyos is all that bad for driver training. If you can get good at the sharp falloff of them, driving fresh tires will be easy in comparison. For me, I've given up on them even though I get them for free. It's just not worth making my track time less enjoyable.

Josh and I will be out at MSRH again this weekend experimenting with more setup stuff. As we are still learning with the softer setup, I'm curious if the Hallett setup will work well at Houston or if the soft setup is going to want something different at every track?
