Though they do not affect speed or acceleration, a few of the engine modifications do affect performance in so far as they increase traction. There is a conflicting statement in this regard, which would need to be corrected. iamxaml (talk) 15:54, August 20, 2017 (UTC)
- Engine modifications increase acceleration and overall power
- Engine cover modifications are purely cosmetic and do not change performance in any way.
- Traction is affected by tyres
- Handling is affected by suspension (barely)
- Braking is affected by brake modifications
