Smoke them tyres Member 557 Member For: 16y 11m 1d Gender: Male Location: Brisbane Posted 15/09/11 04:13 AM Share Posted 15/09/11 04:13 AM (edited) Hi XR,The vid and the photo are very helpful.Looks like the Z only had the benefit of initial turn in.Looking at them, it confirms to me it needs some more front to rear transfer. The understeer after a few laps is also a good pointer of the front still carrying too much load.......it starts somewhere in the window, and then it gradually goes out of "balance"....ie the grip does not sustain itself equally at both ends of the car. It should maintain balance pretty well over a run if all tyres are seeing similar loads.Through the driver's seat when correctly set up, you should feel it squat somewhat in the rear when cornering load is applied.I say that because rear wheel drive passenger based cars basically corner on the outside rear with the front end left to induce cornering yaw.The rear pad situation....hmmm....not good at all. Those belong in the nearest lake. Edited 15/09/11 04:15 AM by Smoke them tyres Link to comment Share on other sites More sharing options...

Guest XR09 Guests Posted 15/09/11 06:40 AM Share Posted 15/09/11 06:40 AM The fastest way around a track is not necessarily being the fastest in every corner. Sometimes you have to give a bit in a section to come out on top over the whole lap.And you have to remember these things are bloody taxi's. Quite flexible taxi's. Not sports cars not matter what the stupid badge on the side or boot says.And XR listen to Rosie. A bar is an aid. The springs really do the work. But to get a car up to spring weight for the track will make it an absolute pig on the road. An unbearable pig.Stiffer springs and a whole roll cage to stiffen or keep the chassis together would be good. Link to comment Share on other sites More sharing options...
