[Fot] Road America - Best gear ratio?

[rocky spitfire4.com]

Oh, hell yes!

I did the Runoffs there in 2011. Had a 4.55 in the Spitfire. My friend brought me a 3.89, but my first session was first group out Monday, no time to change it.
With the 4.55 in the car my 3-4 upshift was halfway up the hill after Turn 14.
With the 3.89 in the car my 3-4 upshift was under the starter stand.

Amici, For the kastner cup Race at Road America what would be the ideal rear end ratio for a TR4?  Last time (2013) it seemed I could have used a lower ratio?
Would a 3.50 be the better choice over the 4.10 I have in the car now?
I Redline at 6000 RPM.
