hmm, thats a pretty vague def wrt to speedo. Stock is only accurate to ~5% of true
any way I have 2 sets of wheels and tires, same sizes. The Speedlines are fine but heavy, on my 993 I use Speedlines for street and BBS for track, the BBS w/ MPSC are 42# lighter and this is much appreciated on track
If you track the car a lot, a separate set of light track wheels makes sense, if you only do an occasional track day it doesn't
just as a side note on my C3 I have 8 & 9.5 x17 Kinesis w/ Dunlop Star specs 225/45 & 255/40, total wt 180# compared to BBS/MPSC 225/40 and 265/35 on 8 &10 x18 with a total wt of 162#
