Only downside is the labor associated with installation of the 10% OD lower. Which isn't terrible but the offset and the first "HOLY CRAP" after you drive the car and that first tip into the throttle you'll forget how much you spent!! I've got a couple of locations that might be able to accommodate your lower balancer installation that I've supplied parts to in the Long Island area. Please feel free to give me a call and discuss 561-445-7702
The 10% lower is considered a 3-4 LB lower as in 3-4 PSI of boost. You'll likely see about 16-17 PSI on your boost gauge with this set up and a significant increase in power with excellent drivability.

Fantastic, that's exactly what I'm looking for. It looks like I already spent my tax return check ;-) I'll give you a call when we get closer to spring.
