1st gear is more of a bitch to get into than any other gear- but as long as you rev match it should be fine. I had a friend on an autox course drive my car and he was on the top of first and second- shifted 9 times around the 30 second course! So- if he can do it, I can learn to do it. I've been practicing for a while because i know its been tough to get into- just not autox course ready to be shiftin like that.
Cliff Notes: It can be done with rev matching with enough practice.
