Section GH Type - Std. - Elise Rimstock, cast alloy, 8 spoke, Hi-power Silver - Exige Rimstock, cast alloy, 8 Y-spoke, Black - Option Rimstock, lightweight forged alloy, 7 split-spoke, Silver painted or natural anodised finish. Front wheel max. load rating 255 kg Size - front - Elise std 5.5J x 16 (cast) - Elise option 6.0J x 16 (forged + AD07 or A048) - Elise option 6.5J x 16 (forged + A048) - Exige 6.5J x 16 - rear 7.5J x 17 Inset - front - 5.5J & 6.5J + 31.3 mm - front - 6.0J + 25.0 mm - rear + 38.0 mm PCD 100 mm Wheel bolt torque 105 Nm (77.5 lbf.ft) Centre spigot hole diameter 56.5 mm Radial run-out at bead seat 0.3 mm max. Lateral run-out at bead seat 0.3 mm max. Note that the inset figure is the displace- ment of the wheelrim centreline relative to the wheel/hub mounting face. A positive inset indicates that the wheelrim centreline lies in- board of the wheel mounting face, whereas a negative inset means the wheelrim centreline is outboard of the mounting face. Wheel Bolts The wheel bolts used are of a special design to suit the small diameter fixing tun- nels in the wheel centres. The bolts have an M12x1.75 thread, 60° conical seat, and a 10 spline socket head for which a special exten- sion tool is supplied with the car. A 17 mm a/f deep socket and 1/2 inch square drive wrench should be applied to the extension tool, with a tightening torque of 105 Nm required. Note that on models specified with up- graded, 4-piston, front brake callipers, the disc mounting bells are increased in thickness to provide the necessary wheel clearance to the callipers. This also demands longer wheel bolts which use the standard spline head, with no coded security bolts fitted:
Standard bolt; B117G6000F 26mm thread length Head outside diameter: 22mm Long bolt; C117G6000F 28mm thread length Head outside diameter: 19mm To protect against wheel theft, one of the four bolts securing each wheel is key coded, and requires a corresponding coded extension tool. Rotate the tool until full engagement into the bolt head is ensured before applying release torque. Note that an alignment mark is provided on the coded bolt head and tool to aid refit- ting. Both the standard and coded spline drive extension tools are stowed in the vehicle tool kit, and should remain with the car at all times to allow servicing to be performed.
