The MK3 Focus RS for example had a really pronounced rake for exactly this reason. I recently fit coilovers and ever so slightly increased the rake (rear is approx 5 mm higher than the front, over the delta from the stock values), hard to say if it made much difference as the car handles different to the previous setup, but that might be due to the new shocks and springs. ie I have no way to isolate the effect of the rake. Personally I would let a race shop near you take care of the setup. Just tell them if you want an understeer/neutral/oversteering car. It may take several sessions to dial in what you want handling wise.

The thing is, with the MPS all the way down in the rear it's 600, so that's why you don't see more guys running 590/595; they need a different suspension. Lastly, always remember that the passenger side rear of the body itself sits several mm higher. It's different for every car apparently, but it's absolutely higher. You can go measure it now and see. And even when you bottom out the MPS it's there, so it's in the body. I know, weird. |

I lowered 10mm front and rear from Stock height with Ohlins. Works well for me for Street and many Track days.

I prefer a little bit of rake on the F87 both aesthetically & for track performance. The car is on point with this setup. Very manageable exit oversteer (which I prefer) and sharp on entry. Entry push didn't appear until the fronts were done (corded). I like this setup - but front lips might not agree

On hard braking the car is still a little nervous and I would like to try and minimize that. Also how low did you go and did you do any roll center correction? I got some used Bilstein Clubsports and they are great, appart from the spring groan when low speed steering.

Have not done any roll center correction to this point. So far all we are working on is the nitron setup - I want to get this kit as dialed in as possible before making any other changes.

I guess I brake hard but not into ABS so its a bit lame that the car get a bit twitchy on threshold braking. Maybe thats the downside of the fun short wheelbase.

Mulling over whether the daily bike + a ride share subscription will do for errands etc meaning the M2 can become more of a track car.

I’m considering the Turner monoball for the front thrust arms to help with this as well. Can anyone speak to any meaningful benefit from those specific to this issue? |

I will have our half cage and Cobra Nogaros installed before my next big track outing in the M2C. Trying to find that sweet spot between daily driver and track car. I think it can be done with the proper seat but not sold on the Nogaros being it for me. If not happy with them then going to try the Recaro Sportster CS. Not full on race seat level for the track but I think will still perform well for the intended use.

I'm struggling with the same goals on this one. I'm curious as to why the Recaro Sportster CS are a consideration. IIRC they don't have slots for sub-straps. |

I have an ulterior motive with the CS - looking for seats for my 69 camaro and those are high on the list - so really would like to try one anyways. Can adapt them for a 6pt if need be if happy with them in the M2C. The GT would likely be a better starting point for that though if going with the sportster line.

I wasn't aware that the GT has sub-strap as an option. I really love those seats! |

The only thing about the Sportster line is the harness holes are a bit low. Furthermore, if anybody is thinking of getting a Sportster CS/GT to use with a quickfit, don't bother, the harness holes are WAY too low to be safe (unless you're like 5'4").

At the end of the day the SWB is the enemy at high speed. I rly want to try my mates M4 to see the difference (we have similar mods) that the LWB makes. Quote:
I had the sportster CS seats in my FoRS, they were very comfy but not for bigger people. The hold was better than the M seats on the thighs but about the same on the shoulders/ribcage. Bare in mind im a smaller guy. Also 4 point only and I wouldn't even do that since they are not 1 piece buckets. The Nogaros can pull a neat trick im just too short for... You can ask for a 2nd custom seat base that is much thinner than the "stock" one. With this you can sink about an 1 -1 1/2 inch into the seat for trackdays giving you more lateral leg support. In my case doing this drops my shoulders below the harness holes which is a no go.
