Currently have the vk 70 installed full wrap no problem with signal. Though vk70 pinakamanipis sa mga vk series when i was checking it out

But honestly guys kahit full vk series umiinit parin kotse if nabilad sa araw

Plus points lang talaga uv protection and mabilis lumamig

Kahit vk40 i dont think the extra 3% heat rejection will stop the car from heating up
