aluminum drive shaft for better dyno results?
Ive been researching Al. drvieshafts and am thinking about doing one before I go off to the dyno (to get more RWHP) and am just wondering which would NOT vibrate under my car. Any suggestions? Been told that Al driveshafts come factory on 2004 gt's, is this true? I dont know. Thanks.
Oh, by the way, thanks for suggesting Speedys in Owensboro to all that did, Ill be going there next month for a dyno run, tune, then another run. Ill let ya'll know the results.
