There are some misunderstandings here. The idea that the new springs make us worse off for bump travel is just wrong.
I just pulled apart one of my front corners to take some pics. The bottom line is that the bump travel of the struts is slightly better, ride height being equal, and due to the new springs being so much stiffer, we are in a far better situation than we were for keeping off the bumpstops. I understand that there are some folks that disagree. I would encourage them to pull apart their stuff and take measurements.
The first pic below shows the misalignment spacer shipped to GC camber plate owners. It is the piece that sets bump travel because it’s the piece that the strut shaft’s shoulders push up. All measurements of bumptravel and camber plates have to orient on the location in the camber plate that the strut shaft’s “shoulders” push on. That misalignment spacer sets the strut shaft “shoulders” 8mm below the lower surface of the camber plate.
The second pic is the cylindrical piece that used to be in the GC camber plate. It shoved down the old OEM spring hat, and also shoved down the shoulders of the strut shaft. Just like the misalighnment spacer, it’s 8mm. So the old GC solution shoved down our strut shaft 8mm + an additional 2mm thickness (yes, I measured it) of the OEM spring hat… Therefore the new location of the strut shaft gives us 2mm more bump travel then the old springs. Not less bump travel, more bump travel.
But here’s the big enchilada. The new front springs are 40-47% stiffer than the old springs, depending on who’s #'s for H&R Race you believe. Lets assume 40%. So 30mm of old bump travel would be the same as 42mm of bump travel now. So if your car is the same height as it used to be, due solely to the stouter springs, you are in a 40% better situation with the new springs.
The bottom line is that we are much better off than we were. This bump travel concern is simply new recognition of a 15yr old problem. Now we know that one of the reasons that our car was such a handful at 'the limit". We are now in a better situation because a) 40-47% stiffer front springs so the new springs require far less bump travel. b) The new springs bring adjustibility so we can lift the front a bit higher if we want, like the Aussies do, and c) our top hats are now compatible with conventional camber plates which will give us, I dunno, 15-20mm more bump travel if someone decides that “better” is not good enough.
