How well does your spouse (or gf/bf) know your car?

Z1NONLY

I race my car and my wife is sort of like a "Team Owner". She expects it to cost money, but she expects me to get something for the money I spend. It's not uncommon for her to ask me how much time I expect to shave off of an average run for a given expenditure.

When I first started autocrossing my Base model 350, I had about $1k burning a hole in my pocket and decided I wanted to order an exhaust. She asked how much time the exhaust would shave off of my runs. I was only expecting 5-10hp max so I guessed the difference would be a tenth of a second...maybe two tenths. We were only dating at the time but she stopped me in my tracks when she asked how much time a LSD would shave...Well, THAT would probably knock a whole second off an average run compared to the open diff my Base came with. The Quaife LSD was my first mod.

Now, almost a decade later, she is my wife and I still have not bought an exhaust. Lol.
