Suggestions to cure poor turn-in
I've owned the MC for a little over a month now but I find the turn-in response a little slow. The car rows quite a fair bit before settling down for the corner, adequate for sweeping corners in a road course but rather lacking for autocross or tight twisty canyon sprints. I find it particularly difficult when negotiating quick S-bends as there is too much weight transfer from the excessive body roll.
Anyone here autocross with their MC? Anyone here with KW V3s that can share their experience? Thks!

Auto-X with the M. Slalom kills my time, among other things.

lol... that about says it.
For a quick one, you can also run higher tire pressure up front.

In my experiment with turn-in response (finish braking to turning in) and steady state balance (from apex to track out), I found that lowering the front ride height by 0.5" (from stock) improves the turn-in response without altering the steady state balance significantly.
I used 245/35/18 in the front and set the coilover to 0.5" lower last weekend and was happy with the result. Here is a short clip |

Think the post title is wrong and misleading. Initial turn-in is fine but rather its the time it takes the car to settle that bothers me. I find that the body rolls and pitches a little too much for my liking, particularly in quick S-bends where the body weight takes a long time to roll from one side to the other, resulting in some instability and easy loss of rear traction? i apologise if I made this even more confusing... newbie.
I was thinking a thicker anti-roll bar may help but there doesnt seem to be any options out there. I'm also considering coilovers but would like to be sure that it would help cure thie 'issue' before investing big $$$ into a coilover system.

Nice video. I've only been to TWS once so far in the coupe, and I have a ways to go before I reach 140. I do enjoy that track, and the Coupe is much better there than my E39 M5 Talk about waiting for the weight to settle. Did it once, will not do it again.

Stiffer springs and matched dampers [typically lowered but not always] will reduce body roll at the cost of some ride comfort. Most of the quality coil-over setups will reduce sway and provide significantly better handling. Several vendors offer bigger anti-roll bars for reducing side-to-side sway.
Alignment and especially corner balancing will help reduce any pendular front-to-rear sway. This car is not lotus-light but it it stiff and can be made to corner flat and fast. |

One thing this will NOT do, though, is reduce weight transfer. It just makes it transfer faster. |
