Selling away my two sets of Gorilla (http://www.gorilla-auto.com/) wheel locking nuts. Selling them because I changed the wheels/rims of my car and the new wheels use tapered lug nuts, not these mag seat lug nuts that is commonplace for newer Toyota, Mazda models' OEM wheels/rims. They are about 2 years old, a bit grimy (can be washed). One set has a nut with superficial scratches due to my own experiment of trying to remove it using pliers (wasn't possible). Wheel locking nuts deter thieves (esp across the border, when parked overnight) from stealing your nice looking rims for quick money. I know my OEM Toyota rims will cost me S$300++ each if I had to buy them through the authorised distributor as replacement for any severe damage or loss.. One set is S$50 (originally about S$70), and comes with a key, 4 locking nuts, and 1 sticker with serial number (to order spares if you lose the key). Buy both at S$90 and as a bonus, by some stroke of luck the keys to these two sets are identical despite different serial numbers! So you need not worry too much about losing just one key.
On work days, we can meet at around Commonwealth/Clementi/Dover area instead.
