Until November I had a 172, I now have a 182 with cup packs.
Daily Road use.
Acceleration wise they both seem pretty much the same, the 182 seems to pull a bit harder for a bit longer to me, I was running a Ron98 RSTuner map on both.
Handling wise, the cup pack is spot on. It seems squirmier under hard braking, but nothing that you can't handle. With it being lower, the ride is a littler harsher, but I've done runs from kent to newcastle in in with no problems at all. Just stick the cruise control on and , well, cruise
, come out the other end still being able to walk.
182 gets slightly better MPG, I average between 2 and 4 mpg better on the same work run. Though some of that might be down to cruise control, so less of the accelerating slowly overtime
