Lift 45mm in front yes, Down travel stayed the same as the bottom bump stop is still in the same position (as you correctly said the lift used up 45mm of the already down travel.The wheel has to travel less, but the total travel is still down to the bump stop. Upwards I lost a bit in theory. I quickly went down to my car and climbed a low brick wall, I actually didn't loos upwards travel, as the coil spring is compressed fully at about the same time as when the upper control arm reaches the bump stop. But the front wheel has to travel up longer to get to the bump stop (probably the 29mm) you referred to. The rear was lifted 10mm to get the car level again. The diffidence will come in here depending on the size of the spacers one chooses. to much spacing will result in the coil compressing totally befor hitting the bump stop.pierreandre wrote:With bump travel, I meant upwards travel to the top bump stop.Bostokkelos wrote:"because you may never reach the bump stop as the coil may be fully compressed before then. Since its a progressive coil, you don't even have to compress it fully before this happens."
Pierre, I am not sure of the Gen models but on the Sport I have a bump stop on top ans well as on the bottom. As it was a concern, i tested it. Down travel is not a problem, the car still have all the down travel to the bump stop, in fact its happens easier due to the fact that the spacer (when there are no weight on the wheel) compresses the spring down forcing the wheel down. But when the cars weight is on the wheel it forces the car up(thus the "lift) as the wheel is on the ground and cant be pushed down. its the "up" travel that is actually a bit less on my car ( because of the reasons you mentioned) Due to the fact that the spring is under more tension, and lost 16mm of upwards movement.
What I meant with less down travel was that raising the suspension uses up some down travel. You still get the full articulcation, but it now consists of more upwards travel and less downwards.
It looks like you got the following results:
Lift: 45mm? (If I remember correctly)
Upwards travel: +45mm - 16mm = 29mm
Downwards travel: -45mm
Does that sound right?
Conclusion....If you want to do a lift...DO IT it works well.

Thanks for the input Pierre!
