In-car 914 on track Options

[Dave_Darling]

Some footage of a four-cylinder 914 out on track. The first corner is a bit ... scruffy, but he gathers it back up and gets going reasonably well.

Actually i shouldn’t have been that specific

It would depend what the current spring rates, and both anti sways are currently. Plus a trip to the scales and potentially adjusting ride height or the rake

I do mean grip

Agreed he may be on the limits but still see a little push starting the corrections

I agree with softening the front

Yeah - it’s an interesting video. Wish I had data acquisition to go with it to understand the car more.

It oversteers, it understeers, and is neutral at other times. Driving behavior has huge influence in how it shifts between these behaviors. Sometimes I see him go to the throttle and then the understeer starts as the front end unweights. Can get the opposite (oversteer) effect by abrupt lift throttle and braking while turning in.

Then there also appears to me to be some aerodynamic changes where it oversteers more at low speed but less at high speed. Likely front end lift at higher speed providing some front end lift and increased understeer behavior that prevents the oversteer at higher speed.

Again, all reasons that simply copying what works on the track may not be the best thing for the average guy driving on the street.

Thanks for understanding the intent of the previous post. (IMG:style_emoticons/default/beerchug.gif)
