I own a '96 Cobra with 110K miles. The engine is stock (and N/A). I've completed moderate suspension upgrades, MGW shifter...I'm considering swapping out the 3.27 gear with a 4.10 or 4.30. Any recommendations as to which ratio and why? Also, my stock clutch is going. I'm looking at the Exedy Mach 400 Stage 2 ($245 @ AM). It's a random consideration based on reviews I've read. Any suggestions regarding clutches, brands etc? Should I replace the clutch cable, and is a speedo gear a good choice for re-calibrating the speedometer? Lastly, if anyone happens to know, approximately where would the rpm be hovering at 65/70 mph if I installed a 4.30? Thank you for your time.
