For some time I debated Guards Red Instruments and Seat Belts before placing my order. In fact it plagued me for some time after the order went in.
Anyway, after taking delivery of my car I subsequently changed my mind about the Red Instruments, although they look mint I have come to terms with it fairly easily, however, Black is what I should have gone for but was persuaded to stick with the standard by friends. As the Seat belts can be retro-fitted this remains an option albeit more expensive.
If you do go for both, now this is my opinion, the red stitching doesn't really look right, perhaps too much red. I'm not sure if this red stitching is standard if you order red clocks, if it is I'm so glad I never went for it.
The seatbelts matching the brake callipers looks just right.
