Different tune, different driver, maybe started at different times? Stock G6ET's are getting well into the 12's as are F6's, so I'd say they're fairly even.
New turbo's with the new version (ported) exhaust housing can be had brand new from MTQ for them sort of dollars, meaning you would still have your stock turbo intact for when trade-in time rolls around. Surely will
Fitting tyres in reverse? Are you serious? Think about what you just said for a minute. If the tyres were to be put on backwards you'd have to face the front of the rim (with uber super cool painted lip) downwards & it would get scratched up to no end. How would it get damaged if they went on front ways? Also, if a tyre shop can't pop off a set of tyres from some china 20's there is something wrong. Just go to your local tyre factory or similar.
Bonnie's is private property & I can guarantee you wont be welcome unless someone has a boat hooked up to the back of their car, and they also have a lease on one of the lakes.
