i'm installing a southsidr machine kit on my car it contains
subframe connecters, crossmember,liftbars and a driveshaft loop
will i see any 1/4 mile time gains?

 

Hey Mean5.7-

I have that kit on my Firebird, but I can't give you an accurate before-and-after, as I converted the car from 2.8 V6 to a 383 at the same time (I think that may have more to do with why the car is faster).

I can give you a warning though. The cross-bar that runs across the bottom of the car between the subframe connectors (and has the drop in it to clear the driveshaft) will be very low in the center. I'm actually thinking about cutting mine back out and flipping it over so the notch goes over the driveshaft instead of under (I'll probably have to modify the floorpan). I was forever dragging that bar when taking dips in the road at anything over 25mph.

Let me know how yours works out.
