Get a Leon Cupra R if you can 
Map to 250/260bhp, Brembo Brakes, better suspension bushes ARB and wishbones.
Also alot nicer inside I think.
Agreed, other than the interior. I think the LCR dash & switchgear feels cheap compared to the golf.
I'm not sure what power I'm running, it was mapped at 205bhp & 245lb/ft. Since then I've added silicone boost pipes, silicone TIP and 3" turbo back exhaust with decat. I'm guessing around 215bhp?
Anyway, I gave a Focus ST an extremely hard time the other week. Completely glued to his rear bumper until the traffic got busier & I backed off.
