1170 kilograms is far too heavy for a 2014 Le Mans Prototype; the regulations stipulate a minimum of 870 kilograms for LMP1-H cars, not including the driver. So you could extract a lot more speed by making it weight 950 or 960 kilos instead.
After a long hiatus, I've picked up where I left off of the Gurney Eagle Weslake. I'm having trouble getting the latest version of SD working (on a piece of crap laptop I've got.) I've got a working version of SD 2.1 on an old Windows desktop, I may just have to use that for testing and setup.
