my front lip spoiler on my P1 with standard wheels and suspension is 125mm from the tarmac.
when parked next to an identical P1 on saturday there was a noticable difference in the two cars with the other being a good 20mm higher all round.
a couple of posts on P1OWC has revieled a difference on a few other cars.
what should the height be?(mike)
why the difference?
