torque spec for 5 lug bolts still 118 ft lbs? recommended tire pressures?
Hello everyone,
Just checking since I don't have my car yet so I am unable to check the manual. Is the torque spec for the 5 lug wheel bolts still 118 ft lbs? Also, what's the recommended tire pressures? Would it be different for aftermarket wheels/tires?
HRE R101:
245/35/20 MPSS on 9x20 wheels
335/30/20 MPSS on 13x20 wheels
Stock turbo wheels:
245/35/20 MPA4
295/30/20 MPA4
Thank you,
John

Yes: 160 n-m (118 ft-lbs)
The 'list recommended' pressure is Part Load Comfort Pressure" which is 31f/36r. This is only suitable for speeds up to 165 mph. If you're going Open Road Racing you'll need to up the pressures...
Pressure recommendations / specifications will be the same for aftermarket tires assuming they are the same sizes in terms of width.
On a 335 rear you can drop the pressure by a pound or two, but the TPMS will complain so keep it at 36 (IMO).
