From memory it's 1mm, the Athena is more reliable imo though and personally I'd pay the extra for one of them especially if you are keeping the car for a while.
The Livesports aren't flared like the Cruise ones, they are probably just as wide but the whole wing curves out whereas on the Cruise wings the lip around the arch is properly flared. They both give awesome stance, it just depends what you prefer.
Yes mate, it was decked and was super clean when I brought it back from the engineers. It was sitting around for several months though and unfortunately it wasn't as silver when I started assembling it. Everything else was spot on though (bores etc). Engine build is in slow progress now (I do a bit on the weekends) so I'm hoping to have it out in August.
WEPR are very highly rated, we are a UK distributor for them too and have several happy customers who have bought WEPR products from us. Zisco and Race-Tech are also worth considering too.
