Calling all STS Fbody owners
For all of the STS fbody owners that are out there I have a question for you: What rear gear ratio are you running?
I tried 4.10's whe I first installed the kit but noticed that I was in full boost for a very short time before I had to shift but I loved the hard acceleration.
I then tried out my OEM 3.42's and lost that initial hard acceleration but gained a much longer full boost period.
Comparing to some of the vehicles that I raced before with the 4.10's w/boost i walked away from them like it was nothing.
With the 3.42's and boost it was a much closer race at the start but once I reached full boost I pulled from them like the 4.10's
I tried 3.73's in my previous 3.8L Fbody n/a and was not too impressed with the acceleration gain.
I'm just curious to see what setups others are running with the STS. Thanks for your input!

I have 3.55's......it's a Moser 9".......you hit the nail right on the head when you said the 3.42's gave you a longer boost period......with the 4.10's you just have too much load on the motor in such a short amount of time.......really depends on what you want to do with the car though......street car, track car, a little of both......if you're going to stick with the 10-bolt then I'd go with the 3.42's or 3.73's....just my 2 cents....

3.42 was perfect with my custom rear mount.

You can spool faster with the taller gear. Stay with the 3:42's and get a 2step.

I haven't actually been able to get my kit put on. And also got a harlan 2 step, moser 9" with 373 gears. But, If you think about it your rpm run up faster with a 411 vs 373 or 342 and a turbo usually don't spool till about 2500 at the least. So pretty much if you go with a 411 your killing the turbo spooling range. You will run out of rpm range before you can get the full potential of the turbo. I don't know if this makes sence to you but it does to me in my head. Hopes this helps you.
P.S. Also the guy that i bought the sts kit from had 411's and he hated em so he went back to a 342 and he said he loved it. Made more boost range.
