Do you track the car, any racing or is this more of a daily? I just put in a
Torque Solutions RMM and honestly I'm switching back to stock, I felt like it helped putting power to the ground and shifting but I'm not currently tracking it. I do some autox but my car is stock with some 200tw tires. I couldn't imagine having the race spec on the street without putting out serious power. IDK if that helps, good luck.
