I've quite a few parts from him. The panhard rod adjuster on mine was made from mild steel and rusted within 8 months, but he explained that was because I had bought one of the first batch he had ever made when he was using that style adjuster. He was very helpful with that and sent me out a free zinc coated adjuster that he uses in his current panhards and other adjustable suspension parts for free.
The devil wing spoilers he makes aren't great if I'm honest, they always bend as they are very thin fibreglass and should come with a reinforcement bar moulder into the edge imo. They are also only gel coated on the outer surface, which I think is honestly quite poor as when you lift up the bootlid you can see the bare fibreglass underneath.
As for some of his braces I have, they are fine but they are a little expensive for what they are. They obviously fit fine and all the welds are good but at the end of the day there's very little man hours to go into making or designing them.
Overall he's good, a little pricy, but that's what we get for choosing to modify these cars and not something like a civic
