That won't be the case. We never make a camber plate that will raise the car, or have a higher stack-up height than the stock top mount. If we cannot match or minimize stack-up height we have failed. We go to great lengths to minimize stack-up height in our designs.
On a Vorshlag camber plate + perch combination made to work with the OEM diameter springs (stock or lowering springs) we make a point to try to MATCH the stock stack-up height of the top mount, as closely as possible. This is so we neither raise nor lower a car with the spherical camber plate replacement (see above left). For one of our camber plates made for a coilover spring perch set-up, which goes on a coilover spring/height adjustable strut, we DO minimize stack-up height, to add suspension travel.
For coilover set-ups where maintaining maximum suspension travel for a given ride height is crucial, we offer a 5mm shorter spring perch/radial bearing combination. This is what we normally put on race cars, but all of my street cars use these. They work great. The double row sealed radial bearing is over-engineered and normally outlasts the car. The single row is might last 3-5 years of hard street/track use, so we normally just go with the double row.
While our camber plates are unusual in that they are always sold with new upper spring perches, that have an integral radial bearing to maximize spherical bearing life, we still make them so they do not raise your car. They might look thicker but in practice they won't raise the ride height. Just wanted to clear that up.
