After a crummy performance at the last race, I’ve been thinking and preparing over the last couple of weeks in preparation for Sunday’s race.
As I explained in the previous post, I found lowering from roll center and raising the rear roll center helpful in getting the car to turn as well as have more initial bite into the corner. I also remembered how thick my front shock oil is from carpet season (650cSt!) which definitely hindered the car’s ability to roll into the corner. I am still unsure where to start as far as oil. However, I know that when the heat picks up into the summer, I will need to run thicker oil to compensate. Right now I’m thinking of something between 350 and 450 cSt.
In addition, I want to test combinations of tire sauces, tire warmers, and tire prep times. From observation and people telling me, tire prep is super important on a low traction surface like a parking lot. If I can find a suitable process, it would give me a huge advantage in overall traction.
This week I found a great deal on MuchMore 24A Power Supply and Integy Setup Station. After putting the car on the setup station, I found the rear toe to be unequal left to right with the exact same shims on the bulkhead. Looking at it further, I noticed a ton of play in the arm that I didn’t catch when I built the car. Apparently Xray redesigned the original T2 arms when they came out with the 008. They are supposedly longer and narrower. I have yet to confirm this but due to the fact that I could not shim out the play with even a 1mm shim and the T2 008 has a total 5mm of shims in the rear arm whereas mine only has 3, I’m pretty sure this is the case. BUT, rather than spend over $30 for just arms, I squeezed the roll center holders when attaching the arm and it reduced much of the play. The toe is the same but not what it is supposed to be from factory. If the arm doesn’t loosen up during the day, I will just hold on to the regular arms and make due.
We will also be running 13.5 instead of 17.5 motors on the track this weekend. I think this is a necessary change as 17.5 on a long straight and flowing track during the dead of Georgia summer can’t end well.
