I ran 4.5 with the Duo and TC, I have not run my SPX in my sedan yet as it's currently in my WGT. But most have gone up to 5.1-5.2 when running the higher profiles on the SPX.

I use the 18t pulleys on my car. But you can still run the 16t pulleys and be fine, you will just have to run smaller spurs to get the same overall ratio's. I was running a 102/47 last time I think. With the 16t pulleys to get down to a 4.5 you would have to run a 88t or 90t spur. Ya a 5.8 ratio should be fine.
