ive had a quote from marco on here but was just wondering if its worth the extra few quid for either a quaife or a gripper.. im sure i could get away with another std one as i dont really use the car hard but dont really want to chance it... im going to have the car mapped in the new year and cant leave it with someone with the welded diff in as its a total pig.... so going to need to sort one before then.. cheers
