I'm a stg2 w/trans cooler for the past year. I live and commute in the city(hence the auto choice over a rowing machine) so I'd say 90% of my driving is stop sign to stop sign in no slow fashion- I would imagine that's the quickest driving receipt for a 5eat to take a hike.
So far so good...still waiting on an '08 hex hehe....but BMX 20g? Nice to hear. When I started down the mod path I was warned about the 'glass' tendencies of our transmissions but common sense-lack of launch-stuff has kept the trans wrench away...
