The race items added to your car might hold down values a bit, or will limit the market for buyers. Cams and valve springs at 41k and new chain tensioners at 51k may raise a few eyebrows to people. These repairs/mods may scare away people who feel 3.2 liter motors don't need those items at such low mileage and may question how the car was used.
I love Casis Red cars. Probably one of Porsche's best all time colors on a 911. However, they are a bit harder to sell. AIC Auto has had two of these cars in the recent past (one is still for sale on their site) and they tend to sit longer than the typical black, red, silver & white cars.
I agree with others on the price range depending on the ultimate condition of your car.
Again, no offense is intended. Just offering an opinion.
