Pre it seems like you're big bugaboo is getting a solid launch. From what I'm gathering based on times posted and feed back from other members that is what's holding you back from ultimate bad a$$.
Standing on the side lines it would appear that playing around with launch techniques should be your next focus.
I genuinely believe that you've yet to find the best launch method for YOU. Every person has a slightly different methodology when it comes to performing a task, even when the core fundamentals are identical.
Use others launch methods as a starting point and play around with throttle and clutch release, once you find something that is a new best 60ft time play around and try to maximize it....... Then try another method and if It's close fine tune it. Maybe 2 to 4 tries each and then work on the better performers.
And don't forget setup (I'm almost positive you dont) but screwing around with suspension clickers or tire psi can be worth a lot.
It's obvious this is bothering you, you're taking it very professionally. Focus on the fine tuning and trade secrets, they're worth as much as the bolt ons (i'm betting this is where Stratton is knocking off several tenths).
More practice and you got it........ Or you could do autocrossing
