MI6 - My car is at s2 dynamics in rockville.

In response to transfer case reliability: I have had my car with FBO+Meth at the skidpad at summit about 5 times (it really didn't like this) and I am in general very hard on the drivetrain so I'm not surprised the tcase went. I also ran staggered setup (235/35 275/30) for one season although it is hardly a stagger as the tires are the same diameter down to .1". I also had 275 supersports all around for two seasons which I believe may have been a bit too much grip for these power levels (given the parts were designed for 225 tires with no more than 300hp). I think it's worth mentioning that I changed the fluid at 45k when some drivetrain binding started to come about. I would recommend changing it every 30k to be on the safe side, as I think that once the friction modifiers in the fluid start to break down the fluid goes south quick.
No way you go to pats.... I'm always getting stuff done at this shop, tell him Allen says what's up
