I went RCE SS-2 coilovers on my '23 with standard 7k front springs with 9k rears (in place of the 7k rear springs that came with them). This based on my old '17 suffering mid-corner understeer with 4.4kg front and 5.3 kg rear springs. I did *not* want to go with a "square" spring setup, which of course greatly biases stiffness to the front.
I have a few events with this setup, really like it as far as handling balance! Kind of a non-standard car tho, I added tons of ballast to remain in my time-trialling class. Competition weight 3107 lb.
, with spare tire from my '17 in the trunk along with 120 lb. (!) of ballast, distribution is 51.5 front 48.5 rear. So I'm relatively a lot less front-biased than most...
