mysharona Posted March 11, 2015 Share Posted March 11, 2015 Is changing the final drive ratio a 0 points change? and Can the LSD preload be altered from factory spec without out incurring a point for changing the LSD? Thanks Quote Link to comment Share on other sites More sharing options...
ILIKETODRIVE Posted March 12, 2015 Share Posted March 12, 2015 Correct. and I believe so. If it was equipped with a helical LSD and you upgraded to a clutch-type, that would be +1. However, if it was equipped with a clutch-type and you simply adjust the arrangement of the clutches, that shouldn't incur a points hit.

AZELISE Posted March 12, 2015 Share Posted March 12, 2015 If the BTM had the diff you are adjusting and you adjust it outside of factory spec, it seems like +1 to me. Quote Link to comment Share on other sites More sharing options...
ILIKETODRIVE Posted March 12, 2015 Share Posted March 12, 2015 Yup, they're right. I forgot about the modified wording part! Quote Link to comment Share on other sites More sharing options...

TurboShortBus Posted March 16, 2015 Share Posted March 16, 2015 Can the LSD preload be altered from factory spec without out incurring a point for changing the LSD? Hmmmmm, let's check the rules... D6) Changed or modified limited slip differential (or welded/locked BTM LSD) +1 You would be modifying the LSD if you do what you are proposing. Therefore...
