Hello from Htown! I've had my 2015 FiST since April of '18. I LOVE IT! I don't know a whole lot about cars (and this is the first stick I've driven), but I've been making efforts to learn more. Right now I'm seeking some advice on maintenance (and hot tips) that perhaps the owner's manual doesn't cover. For oil changes a friend advised me that I should go with Amsoil at 5k mile intervals. I trust his advice bc he works on cars as his dayjob, but what do you think? * What tools should I get ASAP to start fiddling and tweaking? What can I tweak as a newbie? * Should I get a COBB stage 1 power pack? First mods? * I have trouble shifting smoothly from 1st to 2nd for some reason, as it jerks a bit. And shifting in general feels a bit too mechanical; should I lube the gearbox? * Even on the highway the ride is a bit bumpy, should I get fatter wheels? Will fatter wheels improve performance? * What should I inspect ASAP to make sure everything is ok? Thanks.
