The Leon Cupra r has a quick rack and the TT225 does too BUT I would suggest that when you go to see/buy a quick rack you bring a vice-grips or similar and check that it is 2.7 turns lock to lock. Any more and it's not the quick rack.
I got caught out on buying one and then went to see about four or five so called quick racks before getting an actual quick rack.

Also, on the net some people make it sound like the quick rack is amazing compared to the standard rack. It's great for the first two days and then you get used to it!
Good idea if your standard rack needs replacing though.

 

Cheers, it's actually to replace a leaking rack in a cupra r, so need the quick one.

I read that's it's all the Quattro TT's that have the quick rack, as opposed to just the 225, do you know if this is the case?
Great idea on checking, thanks for that. I assume it's 2.7 turns from lock to lock. I know the standard one is 3.5 or something so should be easy enough to tell if it's still in the car.
