I did my first ever trackday yesterday with my 16VT. All went fine, no smoke/leak or something like that (well, not more than usual :D), it was pretty fun, but the performance wasn't that great.
Brakes were poor (I bled them the day before, but in a rush so maybe not correctly), and they lost in performance during and after the trackday, I couldn't be consistent with them.
Tyres were squealing in every corners, probably understeering a lot as turning was not smooth and precise ; I did reduce the pressure to 2.7/2.6 bar on the front and 2.4/2.3 bar on the rear after the first few laps but that didn't seem to help. Road tyres (Hankook Ventus Prime 2) in good condition but 4 years old, is it normal ? I probably didn't help by engine braking to compensate poor brake efficiency, but even with low throttle it was squealing.
On the long straight I was sadly overtaken by everyone, but they were probably more powerful than me and arriving quicker from the previous corner
and the laps I recorded were around 2 min while I think the car would probably be able to do between 1min40 or 1min50.
Car is stock (may not have its full power as it still seems to misfire here and then at idle despite some repairs but I don't think it's the main problem), I use standard parts (not performance) for replacements.
On the front, struts were completely changed recently (except the springs as they look intact) + the wishbones + ARB droplinks. On the rear I only replaced the shock absorbers.
Brakes were renewed 3 years ago but have less than 10.000 kms
Any thought on the behaviour of the car ?
And I would like to improve the car behaviour but stay as stock as possible and keep it road friendly as I use it daily, so probably upgraded brake pads, new performance brake fluid (+ new brakes lines, I bought them) and I suppose tyres ?
