anyone would get a cheaper genuine part, some "performance stores" will charge more for a same part that you can get from traders here and will try to sell it to you more than rrp and i have seen it happen so many times.
like we all seen greedy prices from some autobahn stores , im not saying they are bad but the prices are ridiculous when you can get same part for much much cheaper form traders here on sau.
if you know what you are doing and know the prices they will want you out of their shop quick smart because they cant rip you off
