Hi guys, Seeing as I've been asked and also seen a few questions thrown up about the two 911 GT3 Cup Porsches we now have in game, I thought I'd fill in some details here. Both about these two cars and also some general development stuff they've received. Porsche GT3 Cup Deutchland This is the new one. Porsche Carrera Cup Deutchland (referred to as PCCD from here on) uses the same specification car as The Porsche Supercup and Porsche Carrera Cup UK to name a few. Based heavily on the GT3 road/track car but with a more substantial FIA-spec rollcage as well as being put on a diet. All the cars are the same, with any adjustments highly restricted. You've only got rear wing, tyre pressures and camber to fiddle with and there's no ABS or traction control. I know personally a few guys who have raced these and they're notoriously tricky to get your head around. The weight split of around 40/60 with a full tank of fuel is quite rearward compared to anything else racing, and that distribution moves further rearward as fuel burns off during races. Being road-car based means the suspension isn't fully optimised to make the most of the tyres at all times. For that reason they run a lot of static camber and are VERY stiffly sprung to keep the variance in camber, toe, as well as squat/dive in check. When I say very stiff, let's compare it to the 2019 GT3-R. When comparing suspension stiffness we can use a calculated value called ride frequency which is a function of sprung weight and spring stiffness. In that respect, the GT3 Cup is 25% stiffer than the full-blown GT3 car at the front end, while fairly similar a the rear. It's also very close in terms of roll stiffness, or how much the chassis rolls while cornering. All these despite it making around 25% of the downforce of the GT3-class car. Porsche GT3 Cup (Endurance) This is what's already been in game for a while, although it has had some revisions of late thanks to the input of Lorient Racing who run their car in endurance races. I'll begin by laying out what makes it different to the Cup spec car. There's a different philosophy in setup, with the front ride frequency dropping by 10%, as well as a 2.5% softer rear. The front/rear balance is re-aligned by a heavier front anti-roll bar in conjunction with a softer rear bar. That gives it a higher roll rate (the amount the body rolls during cornering) which brings a more traditional and predictable feel. We have ABS and traction control systems onboard, which take away a lot of the issues a driver has to learn to drive around, especially the ABS system. With a switch to different tyres (closer to GT3 spec) we no longer have to run quite to much camber, so there are changes there, as well as tyre warmers so the car is more forgiving straight out the box. Beware of that when switching between the cars, and don't expect the same changes to camber will work on both cars, because they won't.
