It's very fun to keep it bone stock and just slide around corners, I agree. Just don't max it out and try to run it at Sarthe... It's got the pace to be a contender, but has the dreaded pendulum swing at high speed braking that all older cars with no rear downforce have. So it'll randomly decide it wants to de-stabilize and slam you into the side wall. Sadly, the Honda RA suffers the same fate, and I'm not in the mood to spend hours tuning it to get it out.
Really hoping they update it to give us another wing option (even an identical duck tail with a max of 100 would do it). This would probably make it my favorite Porsche in the game.
Kudos to the modeling crew. It looks great, especially with that old iconic livery
