Your apparel is Level 1 so it isn't going to do too much but the clubs are 4-5 Meter speeds so they should slow it down a bit. It does also help to play with a ball that slows it down too.
I sent you some WGT balls that have the same meter speed (2.5) as the popular L33+ Triple Tracks which have the same meter speed to try out.
Also try closing the app and reopening it if you just rented and equipped those clubs as they sometimes do not load properly when first rented.
It's also a free rental weekend so you could try renting some of the brand name clubs that are L27 or under for free for a couple days. They might be better than the WGT set.
