My front wheels have a 5% / \ camber on them. I guess that might be to help handling. But is this too much and a bad thing. The handling is very good (lowered with 245 tyres all round) but it feels unsettled. I can live with the unsettled feeling but so long as this camber is a positive more than a negative.

if the car has been lowered then it will have a negative camber on th front as the stock upper arms are not adjustable, your tyres will wear out on the insides very fast!

5 deg is very bad!!

245 tyres on the front will fook up the handling as you'll get tramlining, camber steer and slight to major (depending on quality of tyres) aquaplaning in the wet. Even the widest front tyre used on Porsche's is 225 factory fitment and 235 is max size recomendation, but that has more to do with looks than function.

 

5 degree negative camber will help to make it feel more planted on fast sweepers, but lead to oversteer the tighter the bend becomes + your tyres are going to ware unevenly and very quickly.
