I "love" my vehicles as well however my GT86 mainly runs on RON95

Whole car runs in Motul products and 300v.
Only recently changing engine oil to Penrite racing 0, but may go back Motul 300v or maybe downgrade to Penrite Enviro + because they discontinued 0w20 racing 0.

Engine Oil change interval at 8k km, will have UOA samples soon as well XD

FC wise, 6 to 8 km/l lol
Same with any RON fuel from 95 to 100 to VPR Red.

8 injectors bro what to do.
Once I even driven it dry and ended up towing to the closest petrol station
50 liters as per spec with absolutely NO reserve capacity.

It is as the reviews and videos and What not says.
And to an extent, even the exaggeration from MF Ghost (spiritual continuation of Initial D) also holds true.

It's a bit "wasted" on newbie drivers like myself, as it can perform incredibly well in the hands of capable drivers.
But numbers aside, it is simply an absolute bliss to drive a well balanced RWD car that can rival cars with far higher horsepower output especially in b roads/Touge.

Sepang track is a bit difficult with the long back and front straight, but that haven't stop very capable drivers from hitting Sub 2:30 or around that timing which is well within cars that easily have 2 to 3 times or even more horsepower than it's measly 150 to 180 whp 2 Liter NA.

Any decent/worthy modifications for these level of cars are that level of pricing.

Anything less, you're probably better off with stock original.

Despite contrary believe, driving faster would actually stabilize the suspension.

This is because the FD2R and even GT86 tend to run on soft compression (and especially GT86, soft spring rates) with very high rebound.

So if you're going slow and the car constantly compressing and rebounding fighting for grip, it will be a very horrible ride quality/experience.

Once you actually load the suspension by going fast/applying throttle, then the suspension is only on its rebound phase as the compression is stopped via car load.

There are many reasons why people emphasized that these cars are many to drive fast, and this is pretty much one of those reasons.
