My diff ratio is either 2.18 or 2.35 which are the ratios used in the e39 530d. Couple this with 225/50/16 tyres and this gives the ability to reach 80 in third without hitting the limiter.
Are you planning to swap to higher ratio diff? - you'll never get out of Third gear!
You are currently geared to a theoretical maximum of 235mph - in a Sportster!!!!!!?????
