God damn. Someone must have used a screw driver to take the old weights off. I would not like that either. Go back and talk to the manager of the shop.
I assume you have a GT? If so all brakes are Brembos. But the upgraded Brembo's have 6 piston vs 4 piston fronts. The rears are 2 piston vs 1.
The issue with doing the upgrade aftermarket is the rears. The upgraded brembo package has a drift brake AND rear caliper. This means different hardware...
We don't need a separate forum for GT owners. If you look at the 6G forum they just have subforms for all the speciality models (Mach 1, GT350, GT500). The 7G forum just needs to add GTD, and DHSC subforums.
I find track mode holds the RPMs where it should and shifts when it should. I was primarily only using 3 gears on the twisties. They did a really good job on the programming IMO.
Just so you understand, im strictly speaking of the Mach 1 front end. Which the S650s lower valance is clearly styled after. I HATE the regular 2018-23 mustang front end.
Not a DH owner. But I did own a Mach 1 that I traded for a new GT. Obviously its not an apples to apples comparison (I bought my GT as a DD not track car), but I will say it rides much better and feels much more refined than the Mach 1. The infotainment system and technology are a huge leap...
