I got the gears put in on Monday and wow, what a difference it makes. I was apprehensive about it being too much and it affecting drivability - not at all. I read someone say it's like the car is on steroids now and thats the best way I can think to describe it. Pulls much harder - best mod I've done so far.
Just some info for those that were wondering - in my 6mt, 3000 rpm puts me at 73 mph. About 300 rpm higher than before, but not an issue at all. Doesn't have that "need to shift" feel at all.
Only downside is I do have some "gear whine" at about 40 mph when applying drive input to maintain that speed. If I let off the whine goes away during deceleration and coasting, the shop is going to adjust the pinion pre load and should take care of it.
Will update with the adjustment. Best $1100 I've spent on the car by far!
