Referring to the Transmission diagram in the Owner's Manual, in 5th gear you should do 100 mph at 3800 rpm and 170 mph at 6500 rpm. Don't think the stock 951 has enough horsepower to pull redline in 5th gear.

Gear diagram
Here you can see what speed you can reach on stock tire sizes at different rpm. Since many run with 50-100% more power than stock I would believe that reaching 7000rpm in topg gear is feasible with those cars.

I have not had the chance to read this whole thread, but I just wanted to say that Promotion Racing claims that his cars will all do a top speed of 172 mph exactly. He has definitely driven them this fast before. Sounds about right to me.

If it was a 245/50 then it would be a lot different.
