I used a mobile alloy wheel refurbisher who charged me £50 per wheel to refurbish mine - not cheap for a full set of wheels but the results are worth it and in my opinion, these cars are so much better when they are kept as original as possible. If it was me, I'd pay the money and get them refurbished. Just my opinion though. I've seen a lot of LS cars over the years with alternative wheels and I don't think they look good because of the change.
