i have a set of steelies as well, i painted mine gloss black though and decided to do a 2 inch wide arctic blue stripe from centre to the edge and few coats laquer.
4 x 2005 steelies with tyres were £5.50 binned the tyres and fitted some yoko parada spec 2's used them at silverstone and will be back on for angelsey and oulton park. wish my budget could stretch to some alloy 15 for track but they will do for now. not had any issues with brake heat yet the 182 alloy isnt very good for cooling anyway, i have uprated brakes though.
do em gloss and laquer them mate will look a little less neglected, may see you at oulton park sometime we can park our steelie packing clios together lol
