I took my 2023 SE to my first ever autocross a few weeks back.
Owing absolutely entirely to the stock Hankooks not sticking, my timed runs were dreadful. Nothing whatsoever to do with the fact that it was my first time autocrossing and my aggression level was a touch higher than my experience...
It felt surprisingly neutral for an FWD. At the end of my faster slaloms, I may have been opposite lock. The 180s, I mostly ploughed. That was probably a little too much entry speed. I'm really not sure that I want to stick a 25mm RARB on this thing, it's my daily... A bit more maybe, but not a lot more.
Seriously, the tyres did seem rather slick to start with, but I also sucked. After the timed runs, we had some time left so we did funruns. -5s on my first of those, after the car had cooled for over an hour...
2nd funrun was done by an R53 competitor. In her first time in an EV, she ran 0.6s faster than her best recorded R53 time of the day...
Hmmm. I thought it would be quicker than an R53, which is my other car.
My last funrun sounded dirty, but it was also only 2s off the GS class winner. I was very pleased with that.
Methinks that some sticky tyres and a non-showroom alignment, it should easily hold its own in GS.
Brakes are heavily front biased. 280/54mm JustaF56on the front, 280/34mm F54 on the back. I now have some EBC red front, yellow rear to help there. Sadly, the F54 rear calipers make it unlikely that any non-custom 15" wheels can be used.
Suspension is a mongrel. Ride height is a tad higher than F56. Shocks are unique to the SE. I don't have spring part numbers, but the rear springs measure up like an F54 AWD. Fronts may be F55. I strongly suspect the shocks are slightly longer than F56, but shorter than F54. Front spring seat to knuckle distance is the same as F56, so longer spring there. Others have bolted F56 shocks on... My rear camber adjustment is almost maxed out from the factory.
10 runs used 28% of the battery.
Now, you just need someone who knows how to drive autocross to review one.
