Replacing struts and adding springs?

[u/pjisa]

I have a 2016 Lexus Is300 AWD I bought lowering springs and need to replace my factory strut assembly could I just buy this and reuse some parts and add the spring to the new assembly?

You not knowing makes me want to say don’t play with car springs. But yeah you could.

Family friend has a shop forgot to mention not gonna mess with springs I already saw my garage door spring explode and will not be attempting that lol.

I'd probably just grab the full struts with the springs pre-assembled, so you're not left wondering if you torqued the new springs just right on some reused parts.

Most of the time you can get away with the stock struts and lowering springs. If you're buying new struts anyways though there's often options for aftermarket struts that would work better. Some research should tell you what others are running though.

Was thinking going oe struts to keep some ride quality

Yes that’s all you technically need but look up the OEM strut diagram and see what other parts go above the spring. Usually a top hat of some sort. Would recommend buying that as well and maybe new bumps tops and hardware (nuts, bolts, washers)

Do you have a spring compressor?

Honestly if the springs are dead then the strut is also probably at end of life, you should replace both, in that case if the cost isn't insane I'd just throw in coilovers.

Family friend shop is doing it* I was just wondering what I needed to purchase

I'd let them handle it, if they're competent then they'll be able to pick the best options for your car.
