Low on oil should not stop the car from starting.
How much oil did you put in ?
What brand and grade of oil did you add ?
What is the oil position showing on the dip stick now ?
This is weird as you say the oil light did not come on
As above, the only time this happens with me is if I have entered the email addy incorrectly.
However some of the IT gurus on here may have a more technical fix.
You will be fine with the Carbotech XP8.
I would run them with the OEM rotors and see how you go.
Your XP8s with oem rotors will solve your current issue.
However braided lines and proper fluid will help with other potential issues.
Perhaps upgrade your rotors at a later date if you become a track day warrior.
No special tools required and ok for daily use,
Read the compound chart on the previous link that I put up.
Alex.
Carbotech is the way to go.
However, select your compound with care and marry up to a non to aggressive rotor and you will be fine.
I run Carbotech on my track R35, 10 on rear and 12 on front.
An 8 would be my starting point with a stock 370.
