Hi, I'm currently using MT4 at the moment and want to upgrade to 4PKS. Is it a good upgrade choice in term of performance? I'm gonna get it used from local racer. I'm appreciated any feedback, thank you.

In terms of performance (latency times) you are not getting a faster radio in the 4PKS.

Yea go for it is just money!

Thank you, I'll keep the MT4 then.

Mt4= Toyota Corolla
4pks=Lexus
I've had both and ditched the mt4. Navigating the 4pks is soooo much easier, and my fingers kept hitting the trim on the mt4.

What are you hoping to gain from the switch?
