I bought the sportspack fender flares to replace the ones I had that were falling apart. 

I'll be installing them in the near future.  I'm wondering if there is any advice to be had form those who have installed them before. 

I've only test fitted the right front flare and I'm wondering how you secure it to the car at the bottom?  

at the back/bottom of the fender flare there is a hole that doesn't go through.  Am I supposed to drill that through?  

Is anything done at the front to secure the bottom?  the stud location there is at least a bit closer to the bottom corner.  

My other question relates to the seal that goes between the flare and the body.  

The seals I got from minimania are super thin.  They have a bit of double sided tape on the edge that I presume is supposed to stick to the edge of the flare that touches the body of the car (as I'm holding it in my next picture).  I feel that it's optimistic to think this will stay in place and not just push out.  The adhesive strip is super thin and the edge of the fender flare isn't a perfectly smooth flat edge.  

Does the seal just get cut around the a pillar seam cutout (for the a pillar fender seam) or do you wrap it around that somehow?  

How do you get the seal to conform to the indentation for the side marker light?   I though of cutting notches in the seal but don't want it to rip.  

Has anyone tried using this stuff instead?

It looks like it would be more likely to stay in place, as it would wrap around both sides of the edge of the flare.  I would have to cut notches in one side for each mounting stud.  But my main concern is that the fender might be too tick to fit into that seal.  My caliper says the edge of the flare is just under 4mm thick.
