A friend moved to Columbus from the East Coast and is interested in finding a good shop in central Ohio to do some modding of his 2011 135i. He's interested in stiffening the suspension a bit, probably new sway bars, camber plates, installing a LSD, oil cooler, bigger intercooler (probably Evolution Racewerks), improving the intake, perhaps some Dinan tuning. No autocross or drag racing planned, he just wants more spirited performance on the street.
He's the sort of guy who really wants it done right, the first time, so I don't want to send him to a place doing this for the first time on this model.
Rich, Andy, Anson, Kale, Sean, other BMW illuminati ..... can you weigh-in on this with some advice?
Many thanks.
