As Silverstone Synergy M5 user, I would strongly suggest to avoid it. Been using it and should have paid extra rm20 each tyre for Bridgestone/Goodyear.

Im getting good fuel consumption, average 16km/l on Honda City idsi, but the wet performance is really bad. Feels kinda slippery during rainy day, constant hydroplaning, and had wheelspin a few times especially after stopping at hill during rainy day/wet road.

Should had done research before getting it, as many user on the internet complaining about the same bad wet performance.

Works fine on dry road, but seriously bad on wet road.

Yeah it is, and I'm seeing improvement from 13-14km/l to around 15-16km/l after using synergy M5, not an accurate measurement, but thats what the car km/l trip meter is showing.

But for the fuel saving vs wet performance, I really dont think its worth it. Blasting through LDP/NKVE around 90-110kmh on dry, and had to slow down to 50-60kmh when its raining since the car felt slippery.

It was Goodyear Eagle, not sure the specific model as before I had the car, my dad did all the servicing.
