im looking into replacing my stock steel lug nuts with aluminum ones. is there a decent amount of weight to drop? are there any issues with them? i dont want to spend very much, so im looking at these- http://cgi.ebay.com/ebaymotors/16PC-...#ht_7471wt_939
anybody know the size of the nuts on a 92 accord? im assuming m12x 1.5

 

So .08x16= 1.28oz... and using their spec, we'll average stock lugs to 2.5oz.. 16x2.5=40oz. Which is a weight savings of 38.72oz or 2.42lbs or a little more than a kilogram. Considering its unsprung, that can be a gain, however...
Due to aluminum having a different thermal expansion than steel, you may not be able to sustain a torque setting on the wheel lugs. I know there are a few dedicated drag racers who are down to getting the last ounce of weight out of their cars, but even then they have to retorque the wheels before every 1320' blast.

On such a mission critical part, I would not chance trying to save a couple of lbs via the lug nuts. Get lighter wheels or tires if you are trying to save on some unsprung weight. Albeit you can only work on the wheels/brakes when cool as you will get incorrect torque specs or worse stripping/galling when trying to remove/install the AL lugs on a warm/hot car.

IIRC 80's 911 Porsches did use AL lugs, but keep in mind a few things
80s Porsche 911
1. Car weight was ~2500lbs if that
2. Wheels/Lugs were factory engineered/built
3. 911 is a RWD car.

90's Accord.
1. Car weight is ~3500lbs
2. Factory lugs are steel.
3. Accord is a FWD car.
All the power/steering and most of the braking is on the front two wheels of an already nose heavy pig of a car.

Personally, I do not see an advantage of using these lugs on a street car, they would be too much of a safety concern and PITA for any weight savings.

 

alright, i guess i had better just save my money for something else
