The ///M Car Thread

To be fair, if I had access to 6 working vehicles I would buy an M3 yesterday. Maybe.

Oh my god, let it go man.

I went to one of our track days at the F1 track yesterday. It had been a while, more than nine months since I'd been to one (because kids, living in Leon, etc). Of note:

A friend bought and brought two, yes two new GT3 RS Porsches. This one is the Weissach Edition, even more limited:







There were lots of cool cars but it's always like that and I've become used to it (I know how that sounds, w/e) but this mint Countach caught my eye:

I got to drive the GT4 back to back with a friend's M3 CS (identical to mine but blue). Mine stayed in Leon and hasn´t been tracked yet.

Long story short, The M3 CS is quite a bit faster than the GT4 on this track. About 1-2 sec/lap faster. I also liked the dynamics of the M3 better. The GT4 understeers a lot at the limit (I need to get around to adjusting the sway bars) in stock form. The M3 CS has much more neutral dynamics and is actually more fun to drive on track for me.

What was the elevation? Porsches also have crazy long gearing

Mexico City is at 7,300ft ASL. It's a huge handicap on N/A cars. And yes, the GT4's gearing is stupid long. But that's how it comes from the factory just as the M3 so the comparison is valid.

What most surprised me was that I really couldn't catch the M3 in the corners. There the cars were about even with the GT4 understeering beyond the limit and the M3 more neutral/oversteery. On the straights the M3 walks the GT4. Remember that the M3 CS comes on Cup 2 semislick tires identical to those on the GT4.

Might be worth looking into the GT4's alignment. Does the GT4 have adjustable dampers or is that RS territory? I'd def be curious to see them go at it at sea level.

The GT4 has adjustable sway bars front and rear. I think it comes from the factory with both bars at medium. I have to soften the front or harden the rear (or both) that should help as a first step. The GT4 does have adjustable dampers with PASM and on track I run it on the sport (harder) setting.
