GR Yaris Clutch life with mods and flexfuel?

[LOFTY]

Clutch worries, My GR Yaris has a few mods - intake, sports exhaust inc downpipe with cat, Kelford A cams and springs, intercooler, ecutek tune.
Know to the point if I fitted a flex fuel kit, has anyone done these mods if so did the clutch survive (no drag starts!) or does anyone have any thoughts
I should mention I do track days!. I really don't want to go to the expense of a clutch at the moment. would E85 push it into the burning smell area.

I have similar mods to you (no cams and valve springs yet), and my standard clutch started to slip on the track.

I'm quite gentle on the clutch (no launches from standstill etc), but sticky semi slicks put a lot of force through the driveline. Since changed to a uniclutch sport and working well.

The standard clutch will wear out more quickly with increased power, just change it when it starts slipping. The good news is that there are many aftermarket options that will last longer than OEM.

I think that the oe clutch will go whenever it decides to, massive range from mine at 13k miles to others with less and others with more, as Alto says there's good options for better ones at least

If you took care to preserve the clutch I'm sure you could keep it functioning for a few more years. That would mean no launches, no use of NLS, OEM size street tyres only. One might ask however, why add any more torque if you can't deploy it effectively?
