After my car was lowered, and especially after the installation of the Do-Luck roll center adjusters, I had noticed more rubbing by the front tires on the plastic inner fenders than usual.
This usually happens in tight quarters, making turns below speeds of 20kph. In other words, each time I leave my house in my neighborhood, I hear the awful sound of rubber against plastic (the fenders).
Anyway, last time I took the car out, I was surprised to see, that the front left wheel had worn though the "highest" point of the fender - revealing a 12mm bolt! This bolt holds the OEM blow off valve, or some part of it, in its position under the fuse box.
Obviously, not good. Rubbing up against plastic I could deal with, because the rubber tire isn't going to be damaged. But now with a bolt sticking through, could this lead to damage to the tire?
In any case, I wasn't going to take any chances, so asked my Club R33 Facebook friends for some advice. The ideas (all from first hand experience it seemed) ranged from taking off the fender liner and either removing the OEM blow off valve, or moving the BOV forward a few millimeters, to removing the bolt entirely, to replacing the bolt with a flat type bolt.
So last Sunday, as the weather was finally warm and it wasn't raining, I jacked up the car and removed both front wheels.
|It had been such a long time since the last time I worked on the car, I had forgotten why the ramps were necessary....
|Since "OCD" is my middle name...
|On the left, clean wheel. On the right, a layer of brake dust. Yuck!
Feeling lazy, I decided instead that I would cut the plastic around the protruding bolt to see if I could see anything, maybe access the BOV that way. At the same time, I started looking around the entire wheel well, and then discovered to my surprise that, not only had the tire worn out the plastic in front, but it had also rubbed through in 3 places BEHIND the tire as well.
|The middle shows where the undercoating had worn through, showing the primer!
As for the bolt that started it all, I used my Dremel and cut a small square of plastic away, to reveal this:
|Yes, not the smoothest of cuts but check out how much plastic underneath that
had already been worn down!
It appears that whatever it is bolted to, wasn't about to be easily manipulated through this square. So, recalling what Bobby Proctor of Zealou5 advised, I went out and got a flat headed bolt:
|FYI, it's an "M8" size bolt
|which then sits nice and flush, at least 5mm difference (no washers)!
Anyway, until then, it was duct tape time. So I first cleaned the plastic, then judiciously tapped up the torn plastic (both sides, outside and inside, and both front and back, left and right) using industrial strength duct tape, like this:
Of course, just leaving the tape as is after the repair is not aesthetically attractive, AND, we had the problem of where the undercoating had also been rubbed almost to the bare metal. So, I sprayed these areas with some undercoat, in the hope and that it's better to lose undercoat first, then duct tape, THEN plastic. (so I forgot to take photos of how it looked AFTER I sprayed it.... sorry! Have to look closely to see the repair though!)
In any case, while the car looks great with the lowered profile, I will have to figure out which permanent option is the better one, long term. I haven't bothered taking the car for a drive yet as I'm sure the rubbing will continue so long as I don't do one of those two options. Stay tuned!
