What do you guys think of a bolt like this for the towing straps? M16 x 2.0 by 40mm grade 8.8. No idea what any of that means besides that I measured the standard tow hook as as 30mm of thread plus the tow strap is about 5mm thick.

The valleys in between the ribs are very thin metal so very easy to chip or put a hole through. It also goes on a decline from the front of the car to the middle.

180 grit sandpaper doesn't do much. 60 grit is a bit better. Was going to go down to to bare metal but don't have the equipment to go in the valleys.

Hind sight is 20/20 so get a thinner chisel for the valleys.

Aesthetically it looks better and there is a lot of sound deadening in the driver and passenger footwells. This just one coat.

Wonder if a Power Chisel would be a better option, or perhaps an Air Hammer

They have various attachments that can be fitted.

Just a thought.

Some may say an excellent thought as I didn't know such a thing exists :o. However wouldn't surprise me if I ended up with more downforce/ground effect holes that need to be welded up. But I would highly recommend a power tool over doing this with a 5000 year old method like an ancient Egyptian.

It's an Air Hammer/Power Chisel . . . . one uses it with a subtle touch . . . . not like a Jack Hammer.  ;)

Mate the metal is pretty thin in some areas. Such as the rear little lip that joins onto the rear of the car.

Race lights/yellow wrap with with halogen style effect. Looks good from a distance but crinkled pretty hard on application. Turns out another heat gun related issue as you need a heat gun to take out the crinkles.

Tried a yellow wrap but this from a mate and its some professional one that now I found out needs a heat gun and multiple people to apply. One mistake and the whole piece needs to go in the bin. Very unforgiving.

Thought I would try on a simpler surface but still the same as one crease turns into a lot of creases and it stays in the structure. Turns out a Heat gun is an absolute must for it reset to its normal structure.

Here is what the towing strap will screw into. This requires the foam bit behind the bumper to come off or be cut up to fit. This will need a much bigger hole in the bumper as the D Bracket is lower as well.

Pretty proud of this idea as I will use the screw for the metal bracket. It's a D Bracket as well. Probably over kill as it says it's a door strap but almost looks like a towing strap. But it's $15 delivered so probably cheaper than trying to figure out a solution at my Race Supplier - Bunnings Racing Division.

I donít like the angle of force that will be applied to the plate. With its thickness it can just crack and snap. Unless itís some expensive brand name strap. Hence why I stick to standard eye bolts. Yes, they bend, but so what? They are also free.
