Help with spacers

#1
anyone running spacers on your cars? I’ve never had them on any of my vehicles so I’m not overly familiar with them. Just wondering if it will effect the way the car rides or if there’s a potential of it being unsafe? I would like to go with a reputable brand, but just seeing if anyone can give me some advice and point me in the right direction. I hate how much the rear wheels go into the fender.

I’m not wanting to do anything crazy and I do plan on keeping the oem wheels and tires. I’m on trd springs and would like to avoid any rubbing issues. I was thinking of doing 20mm in the rear and 5mm in the front.

Thanks for the video, that answered a lot of questions! Can anyone recommend a good brand or website to find ones that work for our cars?

Would like to hear from anyone that’s installed them, thanks
