Looking nice! Having a 1303 certainly makes the radiator install easier. I agree on the stock 3.88 R&P gearing being too low for the WBX especially with smaller rolling radius tyres - my rears are 215/40r17 and while it is certainly rapid on back roads and I frequently hit 100mph
in it on the way to work, it's not ideal for long distance cruising. I have a 915 box waiting to go in and when I rebuilt it I realised that was 3.88 R&P and 0.82 5th, so effectively a freeway flyer in top - should be nice
What spec is your engine?
