Bill,

Thanks for your factual, data based opinions. It would be so easy for these threads to go way off track into fantasy land without them!

Just with the steering ratios, Tobias Aichele in his book "Porsche 911 - Forever Young" tables the following ratios:
1964 to end of the G Model - all 17.87
964's - 18.48
993's 16.48 (The book's data ends at the first year of the 993)

Regards
Peter
