I tried to clean this up, updating it with all the comments made later. Please note any errors
Cobalt SS
• 171 HP Normally aspirated 2.4 Liter (model years 2005-2007),
* 205 HP 2.0 Liter Supercharged (model years to 2007)
* 260 HP 2.0 Liter Turbocharged (model years 2008,9,10)
• Larger wheels 205/50R17 to 225/40R18
* Different axles, hubs
• 5X110 Wheel bolt pattern
• Larger front disc brakes 11.6” to 12.4” rotor – Goblin rear brakes
• Some with leather seats
• Manual 5 Speed transmission with equal length rear axles
• Some with LSD (G85 code in build label in trunk under carpet)
• Brembo brakes (option?)
* 2.4 L SS has 5X110 wheel bolt pattern
* There are 2 different manual transmissions, a "M86" and "MU3/MC2", Only MU3/MC2s have stock LSD (G85), M86 cannot be refitted with MU3 LSD
* There seem to be more M86 Getrags than MU3 out there.
* M86 transmission is a Getrag F23 - made in Italy 3.84 final drive (Coblat), 4.17 or 3.95 for HHR, ProParts USA carries an aftermarket Quaife LSD QDF17B for the F23. I checked on 5/23/2016 and they had 2 in stock. There also seems to be an OBX aftermarket LSD. Not currently listed on OBX Racing Sports Website
* MU3/MC2 transmission F35 is a Saab designed and built.. 3.82/4.05 final drive, The LSD version is Quaife's technology. A LSD is identified by the build tag under the left side trunk liner - a bunch of codes - look for G85
* The transmission is NOT part of the VIN
Cobalt, Cobalt LS, LT, 2LT – Various trim levels
• 145 to 155HP
• 195/60R15, 205/55R16 to 205/50R17 wheels
• 4X100 Wheel bolt pattern
• Smaller brakes 10.7” to 11” rotor– plenty for an under 1500 pound car
• Manual 5 Speed Getrag F23 transmission with UN-EQUAL length rear axles
• Automatic 4 speed transmission/OD with EQUAL length rear axles
• Automatic transmission models engine sits about 15mm further forward than manual
* 2LT and 3LT model has 5X110 wheel bolt pattern
