+1 to pretty much all of this. I wouldn't be using rake to increase downforce with the cup car due to next to no diffuser, if it helps you point the nose in the right direction in slow corners then go for it, but there could be negatives through faster corners as the minimal downforce gains will be outweighed but high COG at the rear where the weight is. Perhaps rear brake bias and a bit of trail braking can achieve the desired result here.
Regarding how suspension is effected by rake - it directly affects your caster setting so be mindful of that.
I also found no benefit to running the car super low. It just affected stability over curbs and bumbs. Did some testing with the car prerace, dropping it on it's backside was one of hte things I tried and i went back to ~98mm rear ride height. Got my hands on Rolz' and Marty's setups and they were also running in this area. Low isn't always the best option.
