Problem solved.
The guy who runs the car tells me that the problem was in the banjo bolt asembly. I cant seem to understand what it is over the phone, but he`ll show me when I get to the car again. I guess I dont understand as I cannot see why the banjo bolt could cause something like this.
If I get any further info ill post it.
Thanks for all the replies!
p.s. yes it manifested in the cars handling and braking performace...caused wild entry oversteer!
