   Few regulars may know i run time attack. One area where my car differs from all other competetors is in tyre width.
   
   i have found some 15x8.25 rims et0...
   
   never seen these in the flesh.
   
   will 8" rims ruin my handling? I would use 225/45/15 tyre r888.
   
   Most time attack cars just fit the biggest rims they can.
   
   stew

   yes -- unless all the extra width is inboard-all FWD cars must have all rim inboard of hub -nut
   
   eg draw a linw down through the strut and extand onto road --ideally that line should be at outside of rim --or close
   thats why you go wide track and move strut outwards to give more space for rim to come inwards--well one of the reasons
   If i was continuing my development of my rcar ihad planned on 9 " rims to get power onto ground .

   surely to get 9" wheels with that you would need completely custom hubs or you would foul the strut? You could then get a greater angle on the strut with a new hub mounting point and ball joint position so you dont dial in silly camber?

   you just need a satchell front end setup, colin uses 9"s at about et0, dean uses 8.25" iirc.

   these struts have been lengthened to accomodate larger rims +camber angle with suitable new bottom arms also to keep geometery correct
   uses std top strut pick up point
