I tried that stiffer center shock spring and found it really changed my ride quality. I went back the original one.
I think the spring difference (heavier) works better for heavy riders. (guys over 250lbs)

The SRX (21/41) is about 6-7 MPH faster than the T-Cat (24/50) on paper which is likely the real world as all other factors are equal.

Taking gears only into account.

In 1000ft or so (with equal traction) the 24/50 is a good choice for my bone stock 2022 Tcat. I like 21/38 on my 2014 ZR9 with a 300hp tune. Not sure what I will run when I boost the Tcat.

X2.. I’m 210 without gear and original spring is way more plush over the bumps.

Yup! I'm 275lbs and I tried the heavier spring and found it made the ride worse. I Actually valved the front shock softer on the hi-speed side and the ride became less choppy !

2017 stock Winder,185lb rider, cat center spring, no transfer blocks/rod. Couldn't possibly be any happier. Lol.
Odd man out.
I'm considered a "fair weather" rider. I don't go anywhere until I see picks.

Maybe it's because the front track shock is absolutely abysmal without a clicker.

I run the cat 160/260 center spring with just a couple turns of preload and like it a lot.
One turn on that spring can find the sweet spot for a persons weight and riding style.
