Definitely no change to the rear multilink system, pretty sure it's just the shocks that are different between SR5/Sport/regular OR. Bigger rear brakes and larger rear axle comes in the hybrids only.Can anyone actually tell me the mechanical difference between the regular SR5 and sport model? Differences in suspension besides the different wheels and tire combinations? Does the rear multi-link have extra links? Are the stabilizer bars different sizes, or bushing material different? Are the shocks different part numbers?
