It was an official practiceday for the upcoming nordic championship today and I spotted a trick drivetrain mod to increase efficency on Steen Graversens car (one of the topdrivers in europe). He had fitted 20T schumacher pulleys on a custommade layshaft coupled with 32T diffpulleys from the 414. To get the required larger spurgear to fit the bulkheads were raised 2 mm. This is similar to what Xray has done to their cars. I will try to get pics of it next weekend at the nordics.
