I've heard of them - they seem to stock a lot of US kits.
If you are thinking of going for something, check who the supplier is and then check reviews on mr2oc.com.
I got my kit from Gtech on IMOC.co.uk and also on forums.twobrutal.com - he has excellent quality and basically supplies from RMG deveopments who do the Rogue Motorsport bodykits. But Gtech does it much cheaper !
Rogue
Other place I would go to is
Replikit
Most places say "We have great quality but recommend a bodyshop..." but Replikit has introduced a fitment guarantee !!!
