Thanks for the replay.
I have tried different lengths of spring and might now have the one I want to run with. There is not much clearance
I researched the front tyre width as I had a set of Alpina 17" x 8.5" These were slightly too large and the offset was wrong. I had to run with 8" which sit well and provide the proper clearance but only just.
8.5J ET13 have about 2 mm of space on original strut between wheel and strut so tire must be stretched. Will see what fits once I install coilovers I think 8J will be max with same ET + than set some camber so that tire wont rub. Will post it here once I set it up.
