yup two sticks, I expect after having a drive this year I will hear less from the Colonel about going back to an H pattern , and more about refining the two stick deal..there is precious little room for anything that moves sideways, well there is a spot for it but that is in a spot where your arm has little mobility.....that was what we started with.

That arrangement we have has support on the outside, but it could be ten times more precise and ten times easier to dismantle....

Doc--I`m not a great fan of Dot5 or silicon based brake fluid. I have found the minimal water absorbtion claims to be dubious at best, and I have had bad experiences with compatability problems in calipers , wheel cylinders and master cylinders from swelling and softening of rubber components. The chinese or offshore `rubber` in replacement parts now has quite a large amount of `filler` added into the compound, and seems to make the problem more acute. I`m sure there will be others on here that will disagree, and my brake tech experience is 20 years on (although I am still putting cars together) I weould hate to see you have a problem like this in the middle of nowhere. I know Dot4 fluid is corrosive, but some help with bleeding, lots of paper towels and rags and some Non Chlorinated Brakleen still works for me....just saying.... :roll:

my experience with Dot 5 was not goog either. Killed a Wilwood master cylinder and brake light pressure switch. could be wrong, but I don't use it anymore. Phil

If you want something done, give it to a busy person.

Bussier than a cat covering Subaru on a marble slab and 6 Subaru's behind?

Want me to bring my fire suit and compliant helmet for you to use?

At sea level with silicon brake fluid I had a nice hard pedal, good. :-)

At 4000" pedal goes to the floor, not so good. :-o

Back at sea level nice hard pedal, what the heck. :?

Results may vary.

Silicone fluid is infused with minute air bubbles. At sea level they are as small as they can be. At 4000 ft they expand due to the reduced atmospheric pressure and become small air bubbles. The increase in air (size of bubble) in the fluid causes the pedal to travel further; all the way to the floor. The same thing happens when subjected to high heat, how hot was it last summer?

James, instead of 2 sticks, have you thought about trying to adapt an inline shifter, like a Vertigate?

Probably a little late to re-engineer a shifter - Feb 18 and the fun begins. 

My question is will you have time to run in or dyno the engine before you go?

yeah, we have considered various options. The main issue is the space we have, so yeah a sequential is a possibility, yeah shut up Grumm. It hasn't really been an issue for me. As Chris said, time is an issue and as far as urgency there are a few other things I'd change before the shifter.

No we just enter fuel class so we get our names on both sides of the book. We also have the little cheater guards for the back wheels so we can run E/GS if we want....that might be you Grumm.
