Hey Scotty - yes IG has proven to be the easiest channel to push my passion! To answer your question the cars are in and out of Porsche/Ferrari the whole time.
Speciale has gone through 2 geos, 5 Sets of tyres, a wheel hub and a set of pads this year. Ceramic disks were 20% worn all round a trackday or two ago. That's something over 6k miles since end October last year when I collected the car. Had the oil changed 3 times in that time.
918 has just munched its first set of tyres after 2 trackdays and 5.7k miles, two were down to the canvas (since end June). Had the oil changed 3 times in that time. It's been back to Reading (PSO, the only guys allowed to touch the car in UK) 4 times, every time it gets checked over to make sure it's ok. Because us 918 owners to some extent are all g pigs there are a fair amount of updates that need to be doing regularly to the car. They are always tweaking this that or the other. So they send a truck to pick the car up do the update and send it back. I tend to tie in anything not urgent with those so 'my precious' isn't gone too long.
The turbo s I have used on track a couple of times but only on wet days so that car has wanted nothing, not even a drop of oil, 8k miles and tyres got loads of life in them.
GTO has had a set of tyres and pads this year but I've only done about 2k miles in it so that was really an inherited position over the last owner. The car has actually been with Ferrari for the last 4 months because the front air bags keep turning themselves off. There is a gremlin in there somewhere and they have been slow to fix. I haven't been rushing as its been free storage while the car has been luckily appreciating in value.
Will be very interesting how much the RS costs to track compared to the Speciale. I'm guessing a lot less. Pads and consumables are eye watering in the specialie. I want this to be my fave track car because it has the roll cage and harnesses. As it stands the 918 is my fave car road and track. It's an unbelievable machine but it really has taken a trip to France and a couple of trackdays to really fully understand what it's all about. For Xmas I'm treating it to a new suede steering wheel, the valves unplugged in the exhaust (first in the world to try this mod!) and of course it's new tyres and a check up. Looking forward to hearing how she sounds when I get back!
