For the sake of information...
I packed three Spec R front gear diffs with putty and noticed the same as y'all; Stiff at first and then softer, probably a combination of moving the putty around and temperature change. I even noticed the diff softening indoors on carpet, albeit summer indoors at our track can get to 90 degrees at times after coming out of my 75* pit room. I packed three with 3 different amounts of putty, and of the three, the two stiffest diffs eventually broke after only a couple race days. The gears stripped, I assume from the increased stress of the stiffer putty. I would like to try the ofna diff locker or the bad horsie grease next.

Hi, i normally run 2.25mms of shim's in the front hingepins. the wider front setting feels to take away steering (especially corner entry) but when the car is set up right i feel it is easier to drive and carrys good corner speed.
In the rear i have always run 0 shimms in the front mount with shim's only for toein the rear mount. i have not played a ton with making the rear wider but when i have i feel like it is hard to get the rear to roll evenly with the front. wider hinge pins = less roll. from a traction standpoint it could go iether way but normally narrower will feel like that end of the car has more traction.
Thanks!

Maybe we have to switch to the Asso TC6 solution slipperclutch?
I do not have test someting like that but a friend drive the tc6
and it works very well with this front slipper(diff).
Because you have possibility to adjust this like a balldiff.
It look to me very usefull, special for more qualis or finals.
Thanks

[QUOTE=Martin Crisp;9428618]Hey Paul, The narrow and wider track thing has been inconsistent from my testing. The math says that a wider track width will increase the lateral grip because it decreases the lateral weight transfer allowing the tires to be efficient and generate more grip, but to be honest sometimes I have found a narrower track width in the rear make the car more stable and sometimes it makes the car more loose. I think this is the case because sometimes you simply need more or less roll at one end of the car to achieve the balance you want. What are you thoughts?
Hi Martin. I agree with your results, narrowing the rear with the hexs always has more rear grip for me, especially on power. narrowing the rear from the hinge pin will often be opposite, pins closer together means more weight outside of the hinge pins to roll around and take stability away.

Congrats on the National WIN.!.!.!
Paul, Congrats on the Big WIN...
I have a T2 009 that I run VTA with, I am getting ready to rebuild the front end and am ordering the ECS Shafts, Steering Blocks, Suspension Arms, and C-Hubs..... The C-Hubs come in 2, 4, and 6 Degree. For VTA, on Asphalt (i.e. the Asphalt Assault Series).... What degree of C-Hubs should I be running? ........ Thank You and see you at the AA on Aug 21st.

Paul,
Based on my calculations (scratch…scratch) I have concluded that my BBRC motor fan reduces (scratch…scratch) motor temperature by approximately 7.9546632% (scratch…scratch) over the course of an 8 minute run. Given that the (scratch…scratch) readings were taken with ambient temperature at 87 degrees Fahrenheit (scratch…scratch) I have calculated that I should see an average (scratch…scratch) increase in wattage output around 3 watts, over a 8 minute run, if Cleveland keeps the ballroom cooled to 72 degrees (scratch…scratch) by using this fan.
How many (scratch…scratch) tenths behind Josh will this put me?

1/12th ?
Hey Paul (or Eric),
A 1/12th question for you, does one prefer to have a 1/12th body float or should it be tight to the posts? Whats your preference? Also whats your preference for body choice in 1/12th carpet?
EA your suggestion saved me a ton of work and well worth the money.
Thanks

Hey paul do you run any diffrent rotors in your motor also how do you like it is it torquey all high end or simply a good balance? Thanks Paul!!!!!
