It’s not bad. Went to Oulton Park a few years ago and remember overtaking everything that wasn’t a proper track car and overtake them again if they stayed out for more then 10 laps. Brakes were very good, standard road pads, could have kept going until the fuel ran out. However they did start juddering at the end of the day.
Think I did more than double the laps than anyone else as I quickly got bored having a rest and cooling down and couldn't resist having another go. I was doing 30 minutes track time followed by 15 minutes rest, then back on track for another 30 minutes.
Had no mechanical problems all day, just had to keep putting fuel in. Think I filled it up twice. Can’t remember the MPG.
Had Bilstein B14 coilover kit fitted at the time and the rear was a little to stiff so had to counter steer for the back stepping out a few times.
Couple of vid’s on Vimeo, it’s a lot quicker than it looks.
