Both front Kosei K1s cracked

mid-corner fun · 02-05-2012, 03:31 PM

While prepping for the new season I found cracks on both front K1s (2 on left one, 1 on right, all on inside lip). ~40 track days on these, about half with current tires. Rears are both fine.

I check wheels before every event, this is definitely a new development. The only scenario I can think off for the cracks was a very rough transition between infield and banked straights on my last event. There was an actual gap of a few inches upsetting balance on every transition.

Check your wheels, better safe than sorry!

man that sucks. sorry to see that.

Sorry Pete. That does suck. I will say, 40 track days is decent. I would guess that the average person does 5-6 a year. You must've been out there A LOT!

lol, I didn't say that was in one season. I think this is over 2 and a half seasons, I shoot for ~15 track days per year.

Unless I quit my job, I don't see me squeezing in more track days per year

Fine. 15 a year is still a lot. Lol.

For as much as you track your car, I say you pick up a BRZ and beat the snot out of that. That's what I'm planning. Retire the 335i from the track.

40 track day is beast...

so what are you getting next? same Kosei's?

I have seen the front wheels on a set of Kosei K1's during a race have the center of the wheel separator from the barrel while in the carousal at Road America.

I've heard great things about Enkei Wheels

mid-corner fun · 02-14-2012, 08:14 PM

No choice, I ordered 2 K1s for now. If the stars align I'll be running 18" arc8s next year with much wider tires on a different car

Wheels are a wear item. They will all break in time with track use. Good looking out.
