92-tbird lug nut torque ft lbs

I heard that the torque for the lug nut was 85 ftlbs. Reason it was set at the low end on torque was that going any higher would end up warping the rotor during heat build-up when applying the brakes. Is that correct torque?

85 ft-lbs is the Minimum you should set them at. Most of us set them at 100 ft-lbs.

this warped rotor issue seemed to happen when I set them at 100 ft lb. I've replaced two rotors on this car over the years. My understanding was the stock rotors were undersized for this car. This is why I'm trying to remember if it was at 85 ftlb.This is a 92 3.8 base bird not an lx. Anyways,does anyone see any issue at setting them at the low end? Thanks

Not that I can see, as long as all are torqued evenly and you re-torque them after a hundred miles or so.

As for your warped rotors, make sure you aren't getting the cheap "lightweight" rotors most parts places sell:

97 Laser Red Thunderbird LX 162k, Stage 2 4.6L 2v N/A | 300 BHP (255 RWHP, 290 RWTQ) | 13.95 @ 97.58 | Build details | Pics at the Lorain Assembly plant
98 Black Mark VIII 160k, stock daily driver
07 Redfire Fusion V6 SEL 178k, for the wife
Gone but not forgotten: 96 Mark VIII, 94 Cougar XR7, 93 Mark VIII

Service manual says, 85-105 ft-lbs
85 shouldn't be an issue as it's still within spec.

Nice comparison picture!!! I've always heard to buy the better rotors but have never really understood what the differance in quality was.

Minimum or in the middle is a good place to be. I go 85lbs myself. Overtorque will stretch the studs, which is bad...Very Bad.
