I'm about to order a set and have been working out the numbers. (I just posted on the email list where I normally hang out asking about offsets which so far has been pretty much ignored). javascript:emoticon(':?')
Confused
From a tech article on gglotus about the design of the pansport wheels, he states that the offset should be 29mm,
I got one reply off line from a guy fitting pansports to an S2 which required grinding things and such to make them clear. He said his offset was 34mm.

My plan currently is to demount an old tire off of a stock S4 steel KO, measure it as accurately as possible for stock offset and backset, then determine maximum track I can have for SCCA rules (vintage racing) and spec the wheels to that offset. I'm not concerned about fenders; as mine are trashed (cracked and worn through in a couple spots, and rules allow me to 'slightly' flare the fenders for clearance, maintaining stock opening shape. So I plan on doing so.
I assume the offset is going to end up more than the 34mm above, my guess without measuring anything and assuming that 29mm is stock would be about 40mm (1/2" wider track each side). I don't think (hope) 1/2" increase in track will adversely effect steering that much. I'm expecing some increase in steering effort (that's ok) and hoping that it won't impact centering (return to center).
I'm going to be using TTR rear springs (which off hand I don't know the diameter of as I haven't measured them but smaller than stock, and I think are 2.5" but would have to verify).
So given all of this, once I do some calculations and get them which is probably 2+ months away with current restraints I would be happy to measure stock fender clearances and let you know the results of how far off they are from fitting on an S4 if that will help you.javascript:emoticon(':roll:')
