Has anyone moded mkIV Jetta
 

I'm new to the forum and have been looking through and haven't found if anyone has areomoded a mkIV jetta. All I have done so far is grill covers and that's it and I was wondering what if anything else can be done.

Welcome!

I believe there are several on this forum that have modified their mkiv's, both Jetta and Golf. In my case, I've done the grill block and some under-body coverings:

Front under-body (this is the bottom of the front bumper, which I removed to put the coroplast on):

This combines with an engine skid-plate (mine is an OEM steel version, but there are also aluminum ones as well as the OEM plastic under-engine cover)

Rear under-body coverings (closes up the rear bumper "parachute"):

Helga is also lowered by about 1" so that the tires are less exposed.

Would be interesting to see your grill covers.
