Just want to see what others think of this. I brought my car in to have my sway bars installed about 4 months ago and when they put my wheels back on they torqued them to 60 lb aftermarket wheels. When I got home I just double checked the mauals torque specs and it says 80lb. So I called my guy who works on my car he also installed my suspension. Totally proffessional shop very reputable and use good equipement. Well I asked him why he torqued my wheels to 60lb and told him my manual says 80lb. His answer was that 60lb is fine and if I was worried for piece of mind to come back in and he would check them for me and that he guaranteed if I took it too another shop and they set there torque wrench to 80 they would not be able to torque it any further meaning the lugs would not turn more than when original set at 60lb. I do trust this guy and I know he does not have shitty torque wrenches and he knows what hes doing but still was curious So I called a few other places and got various answers. Some said it was probably ok but to double check others said sometimes the manufacture over estimates those torque number fro safety reasons. Another said since its been 4 months with no problems it should be fine.......etc etc. Any one with knowledge on this ???

 

I dunno, I have been working on cars for a very long time and usually we always torque lug nuts to 80lbs. Even most tire shops do this also, and they tell me to come back after a week for them to retighten them.

- Don't argue with idiots. They will bring you down to their level and beat you with experience.=P-

 

I'm with RaySur350GT on this one--- 60 lbs isn't gonna cut it. Factory spec is about 72 - 85 lbs. You should stay with that.

60 is pretty low. I usually torque around 90 for all other cars, and when I found out the G was 80 I was surprised.

Vince w/iForged told me 80 ft-lbs was their recommendation for the Evolutions as well. What concerns me is your mechanics' statement about taking to another shop. Does he have some magic torque wrench that, when used, "locks" the lugs into his setting alone? The last time I studied engineering mechanics ( granted that was quite awhile ago! )
& basic math, 80# was greater than 60# so why wouldn't another shop be able to exceed his 60# setting?? Just curious.

 

I'm with the others on this also. If specs say 80 ft-lbs that's what you should use. Usually wheel manufacturers will also put specs on their rims. In the past mine have said 80-90 ft-lbs and re-torque after 25 miles of driving. I didn't do this once and after about a week I heard this sound when I would slow. I pulled off my center cap to find a lug nut free and banging around with another less than finger tight, not good.

Russ - If U ever make some high ( 100+ mph ) speed runs be sure & check them again, also. I had a similar situation happen to me in my 'Vette. I raced a friend up to 150 mph
( BTW - I won!! ) & when I got home the car didn't feel quite right. I found TWO lugs loose on one of the rear wheels!! These were Centerlines which I checked every 2-3 months but I speculate that the aluminium wheels may have distorted & caused the loosening ( I know it's unlikely that a quality whell like Centerline would distort since they're on dragsters but it's my best guess ).

 

I had centerlines on my Chevelle and never could get them to hold a torque. They are light BUT, I am not putting my safety on the line.

Anybody know what Volk's recommended torque is? All of the paperwork that came with them is in Japanese.

it's not so much the individual manufacturers torque. if you don't torque yourl ugs down enough, they could actually loosen at high speeds or over an extended period of time. also, pretty much all wheels made nowadays are hubcentric, which means it places the wheel at the center of the hub, making the lug nuts merely holding it into place. if the lugs aren't torqued to the proper value, it would put added stress onto the lug nuts/bolts, and may cause catastrophic failure.
