Spohn Performance 987 Features:

Don't use your old rusty mounting bolts when installing front lower control a-arms on your 1993-2002 GM F-Body Camaro and Firebird (if you managed to get the nuts off without breaking the bolts!).The external star locking washer is placed underneath the bolt head to lock in the front end alignment settings at the k-member a-arm mounting slots. These make a big difference on powder coated tubular k-members compared to re-using the factory hardware.Our front lower control a-arm mounting hardware kit includes:(4) 14 mm Grade 10.9 bolts(4) 14 mm flanged head steel lock nuts(4) 14 mm external star locking washers
