I ran a 3.45:1 in my MOD Stag for about 40,000 miles and was happy with it.
Fitted one to my current Stag when it had the BW35, which helped reduce the ridiculously high rpm at motorway speeds. It is still in the car which has had the ZF box in it for the past 9 years, 30,000 miles. The only problem is maintaining speed when faced with a steepish hill 4-up as we were today. I find pulling the stick back to 3 sorts that problem.

Hi, I have a 3.45 in my MOD, happy with it, just got to get out of OD sooner. I kept the 3.7 complete in case I wasn't happy with the change. Speedo is spot on using a speedo drive pinion out of a 2.5S OD.
