Hi Paul, I have put MG TF 16 inch Hairpin alloys, to get the off set and clear the princess four pot calipers I have put 10 mm spacers on the front with longer studs, I have not put the spacers on the rear wheels as I think I would need to flare out the wheel arch.
I have a pair of 5mm spacers if you want to try them with the wolfies you are welcome to borrow them.
Not sure if I will be going to Gaydon, I would like to, as have had some serious health problems and finding difficulties driving the beast
Let me know if you want to try the spacers, I can always send them to you.
Cheers
Moe
