My front left and right fender start to develop notches / ripples at where it closest to the front struct tower bar.

No only mine but also to of my friends... I have a Spoon front STB

Is it because of my stiffer suspension or adding an aftermarket front struct tower bar causing the fender to bend at hard cornering?

 

Pictures?

 

what other mods do you have? have your fenders been rolled?

 

I will try to get pictures later but its hard to show on the camera with white color, I will try to snap some pics of my friends silverstone.


No fender work, just Spoon STB and CR suspension package. And a lot of mountain passes...

 

front tire sizes?

 

215 Dunlop z1

 

Well out goes that theory. I'm a tad confused considering it's the general impression that the strut tower bar's do absolutely nothing other then look pretty. Anyway, I'm out of ideas.
