...and this is why this idea is all well and good, but it's pie in the sky. Nothing definitive will come from any of this as all the cars are in different trim levels, different drivers (sorry, but I'm not letting someone thrash my car around a track, I'd rather do that myself to justify the costs involved - being useless on track however would just prove what I already know: which is I'm a useless driver) so it will prove nothing and wont just be "harmless fun" as it will all just kick off again.
As mentioned above, dyno day is the best option, but again, count me out unless my expenses are covered. I already know it's quick, I'm not paying to prove it as I really could not care less.
