Good morning all,
Busy getting the E12 ready for the weekend - something "small" Ive lacked to do on this car - but done it on the E90, is the front suspension bushes.
They are NOT designed for track use and give a huge amount of flex under braking and cornering - changing the wheel alignment toe.
Which is obviously not ideal, making the car unsettling and unpredictable under mostly braking but also in high speed corners,
See the attached pictures of the std bush - just cleaned it up to be casted solid.
Even when pressed with my thumb, is scary the amount om movement these bushes give way, cant imagine how much they are flexing under hard braking.

Not everything in a build is wow or glamorous,

However adding all the small stuff - it does make a difference
Added 2 bonnet air vents, to assist with under bonnet pressure and heat
Might add a third vent in the center

Looks good! Did you make these yourself or did you buy them somewhere?

Have you done any empirical analyses of the vents? Sometimes that rearwards area of the bonnet can have quite a high pressure, meaning the vents can do the exact opposite as intended
