Daily Driver & some trackday assistance

Hi,

Firstly I would like to thank wmandra and other contributors.

However my requirements is not to have such an badass Z4

I only do 2 -4 track days an year - and the issues en-counted have been:-
feeling unsettled at 90 Mph - bit like wobbly sensation sweeping through corners.
Overs steer mid corner

My z4 is my daily driver, so don't want to aggressive drive. But improve the handling, reading several forums I dont see great value in having coilovers as the car only done 15k miles - so I am planning in retaining my stock Msport struts.

My thoughts are to complete the following work:-
1) Replace Run Flats with Michelin-pilot-super-sport

What to do next
2) H&R Springs or H&R Anti-role bar (upgrading to M3 running gear probably to much for me at this time)
3) Change front and rear camber

Adding the below items - would an novice track drive notice the difference?

My issue is there are so many different components in the suspension - changing one item - will be affected by an weaker element else-ware.

So for my requirements - after replacing to normal tires - what should i change next?


Here are some videos of my exploits

From 19 Secs to 45 Secs - were the car did not feel settled -and i was loosing an lot of time





I did find this track a lot easier to drive
